Rounding out the rotation


On Wednesday, Ron Gardenhire stated that he fully intends on using Brian Duensing as a starter in 2011, presumably joining Francisco Liriano and Carl Pavano in the rotation. By most accounts, Duensing had given ample reason based on his performance last season to keep him as a headliner rather than hide him away in the bullpen. Now, it is up to Scott Baker, Kevin Slowey and Nick Blackburn to jockey for the final two positions.
While arguably capable of being a solid number two starter, Baker’s recent elbow issue has probably caused the coaches and front office to cringe a bit, hoping that he emerges from this setback without any further damage to his arm. News regarding Slowey has been surprisingly quiet this spring. Considering he has now had two consecutive seasons cut short with injuries, you would expect more updates on his developments. What we do know, however, is that in his one appearance this spring, he’s allowed three runs on a home run and issued two walks in two innings of work. Blackburn, meanwhile, had the same offseason surgery that Baker did but has (so far) appeared to return to the mound without the struggles, even going so far as saying his arm felt like new.
Of the three, I would speculate that Blackburn will to be the next suitor to receive Ron Gardenhire’s rotation rose.
Undeniably, Blackburn’s 2010 season was unpleasant – both for him and for us. After a terrific month of May, he unraveled faster than a Charlie Sheen interview as opponents took aim at what seemed to be his hanging fastballs. From June until mid-July, teams slugged .653 with 11 home runs over the course of 10 games. Nevertheless, after a brief stint in Rochester, he reemerged as a decent option for the playoffs (had they continued past Game 3). In his final nine games, Blackburn held opponents to a .356 slugging against and six home runs. With the exception of his debacle against Kansas City in which he allowed eight runs, he held opposing teams to three runs of fewer in those starts.
Just recently we learned that he went through all that while battling an elbow injury and, because of this, he admitted that he was forced to stop throwing his slider/cutter. Although this may seem minor, it likely played a significant role in Blackburn’s messy season.
Last May, right before his best run of the season, I used pitch f/x to present the case of his missing slider. Turns out, either opposing hitters either read the StarTribune’s TwinCentric content (highly unlikely) or they became well aware of his pitch selection shortly thereafter, decimating his sliderless repertoire post-May. According to Indians/Mariners slugger Russell Branyan, who had happened to run into Blackburn at a Garth Brooks concert (Author’s note: okay, Michael Buble concert), Branyan told Blackburn hitters picked up on that fact pretty quickly.
It’s no small wonder why his swing-and-miss rate plummeted last season upon the abandonment of his pitch that was best qualified to incite an empty swing:
Nick Blackburn’s Missing Bats:

2009
5.4%
88.1%
2010
4.1%
91.0%
                 (via Fangraphs.com)
The difference between his post-May-prior-to-demotion-days and his late-season-recall-days in which he had some success is that he stopped throwing his two-seamer exclusively. He worked in his change-up more, giving the hitters something else to think about while at the plate. For the most part, this seemed to work.
Of course, despite the improvement after his demotion, as Jonathan Scippa pointed out at BaseballAnalytics.org, righties were still crushing all over him. The conclusion is that without his slider/cutter, which he threw predominately to right-handed foes, Blackburn was more susceptible to big hits from same-sided opponents without that secondary option of the slider. Adding the slider back to his repertoire should help keep his same-sided opponents from laying into his offerings as much.
Keep in mind that given his abnormally high contact rate, coupled with his unusually low strikeout rate previous to the 2010 season, do not anticipate a sudden breakout season from the right-hander. It’s not as if adding the slider is going to transform him into Roy Halladay. What can be reasonable to think is that Blackburn can tone down that loud ERA – somewhere closer to the 4.00 number – while chewing threw 200 innings. If he can maintain an above-average ability to induce groundballs, shave a few walks off his totals and maybe even strikeout an extra batter or two per game, Blackburn is plenty capable of having a bounce-back season in 2011 and providing the Twins with a solid back-of-the-rotation starter.

Projecting Brian Duensing


Ron Gardenhire announced after Wednesday’s game that Brian Duensing was guaranteed a spot in the starting rotation. This news was pretty much anticipated given Duensing’s performance as a starter the previous two seasons coupled with the other candidates’ injuries and ineffectiveness.

Without question, Duensing pitched admirably for the Twins last season, acting as a vital cog in assisting the Twins to their second consecutive division title. Still, based on his peripherals and his average-ish stuff overall, there are some who believe that a repeat performance is unlikely. On the other hand, Duensing now has proven in two samplings that he is capable of handling the job, perhaps one of those rare breeds of pitchers who consistently outperform their peripherals.

Since we can’t measure heart or analyze his mentality, let’s take a look at some of the data from last year and see if it can tell us anything about his future performance:

As you can see, Duensing thrived in this department comparative to the rest of the league. These are the qualities that a manager loves – get the first guy out and don’t lull your defense to sleep by throwing a ton of pitches in an at-bat.

According to BaseballProspectus.com’s run expectancy chart for 2010, the difference between letting the first runner of an inning on base versus retiring him was 0.59 runs. By keeping the first hitter from reaching, Duensing undoubtedly shaved plenty of would-be runs off of his ledger.


This is unquestionably good. The problem occurs when you ask yourself if any of these skills are repeatable. Certainly, Duensing’s ability to pepper the strike zone and entice contact quickly in the count is a skill that can carry over, but then you have to wonder if more of those batted balls in play will start to go for hits – particularly doing the first at-bat of an inning thereby increasing an opponent’s ability to score runs.

Likewise, Duensing also exhibited some bulldog-like tenacity when painted into a corner last season:

With runners on base, Duensing was able to keep runners from scoring and when he fell behind hitters, he rarely let them off the hook and retired 79% of them.

Given these marks, mixed in with his traditional results of a low ERA and an enviable win-loss record, you can see why Ron Gardenhire tapped him as his third starter. However, the concern over those categories is that they tend not to be repeatable.  For example, Duensing’s 18% runners who score mark is also analyzed as left-on-base% at Fangraphs - measuring a pitcher’s ability to strand runner. This quirky video outlines the influences of the strand rate and that someone like Duensing, who had a vaunted 82% left-on-base%, will be vulnerable to regression.

Furthermore, while wowing everyone with his efficiency and his battle tendencies, Duensing did not impress so much in regards to opponents’ contact:

In general, Duesning’s offerings, when put into play, were fairly well struck. The well-hit averages were not absurdly high, mind you, but enough to lend credence to the notion that Duensing’s miniscule batting average on balls in play in 2010 is likely to change routes next season. Along those same lines, as I discussed last month, right-handers have slapped him around a bit more and with an increased exposure to opposite-handed hitters, Duensing will likely see some of those numbers inflate to some extent.

Additionally, as impressive as his 7-2 record was as a starter last year, some of that has to be attributed to a substantial amount of offense provided by his lineup. His 5.67 runs per start – the 12th-highest in the AL with a minimum of 70 innings pitched - gave him an ample cushion in which to pitch in, much more so than the league-average of 4.45 runs per game. Given that his runs per start will decrease toward the league average and his penchant for allowing runs will increase some, there will be the likelihood of more marks in the loss column in 2011.

Based on the level Duensing has produced at, it imposes an unreasonable expectations for his future production when considering some factors like his miniscule batting average on balls in play and astronomically high left-on-base rate. Of course, none of this means that he shouldn’t be in the rotation –after all, he has not allowed many home runs and has kept opponents off-balanced enough to get them to drive the ball into the ground - it’s just a friendly reminder for people to keep their vaunted expectations in check. If the defense behind him can convert, he’s likely headed for an ERA closer 4.00 which, all things considered, is not a terrible rate.

Why you should take notice of Kyle Gibson


While Tsuyoshi Nishioka may be the center of attention among the position players in Fort Myers, pitcher Kyle Gibson is certainly gaining notoriety because of his stuff on the mound.
For the past few days, the wires have been abuzz over the hurler. Players have attested to his remarkable repertoirecoaches have fallen in love with his makeup and attitude and the on-looking media members have been wowed by all of the above. Judging from those reports, it is no small wonder why Baseball America selected Gibson as the organization’s top prospect or why they think he’s number 34 on the nation’s Top 100 list.
To me, what is really significant about Gibson’s potential and progress is that not only is he tough on same-sided opponents but he has an ability to neutralize left-handed hitters, often a difficult task for right-handed pitchers.
For example, Jason Kubel, a career .282/.343/.497 left-handed hitter against right-handed pitching, raved about Gibson’s stuff:
"He has a lot of good movement. But what really impressed me when I faced him the other day is that he keeps everything down. It sinks a lot. I don't think I saw one pitch over the knees, and I don't think I saw one over the knees the one time I went down there to face him last year. So he keeps the ball down and makes it all look the same. He makes it really tough on a hitter."
Usually, this isn’t the case. Right-handed pitchers regularly struggle with left-handed opponents as lefties typically see the ball longer and do not have to face the pitcher’s breaking stuff (pitchers are reluctant to throw sliders and curves to opposite-handed hitters). This means with more fastballs in their diets lefties tend to elevate the ball better on right-handers (and vice versa). This is why most pitchers have significant platoon splits. Gibson, however, appears not to follow that trend.
Let’s take a look into why Gibson can keep lefties from hitting him hard.
Without much available in terms of comprehensive minor league split data – at least nothing substantial since MinorLeagueSplits.com closed shop, causing this stat nerd to cry a bit – what we are left with is a sampling of his numbers versus the two groups found at MiLB.com.
Unfortunately, MiLB.com, the official site for Minor League Baseball, provides limited information regarding a pitcher’s splits. What they offer is only the player’s splits at the most recent level of baseball played. So in Gibson’s case, we are relegated to the results based on the 15.2 innings of work while with Rochester at the end of the year. What we do know is that when facing righties in the International League, Gibson carried a 1.25 groundout-to-fly out ratio. On the other hand, when taking on lefties, Gibson had a 1.50 groundout-to-flyout ratio suggesting that he was better at getting the southpaw swingers to beat his pitch into the ground.
Where the data fails us, visually, we can see how Gibson achieved those rates.
1500ESPN’s Phil Mackey, one of the biggest hustlers around the Twins camp and a must follow on Twitter, captured some very impressive footage of the big right-hander working to Joe Mauer and Justin Morneau in live batting. From the angle perched behind the catcher, Mackey gives us a unique glimpse of this spectacular movement.
The first clip is of Gibson facing Mauer. Here we see him deploy his two-seam fastball to the three-time batting champ: 
 
Gibson’s two-seamer, often referred to a sinker because of the movement, displays outstanding action. As LaVelle described on Sunday, Gibson can “throw at a lefthanded hitter's hip and watch it break toward the inside corner.” Without question, the instance above is a prime example of LaVelle’s description: As the ball leaves Gibson’s hand it appears to be heading into to Mauer’s belt but halfway home, it starts pulling back towards the plate and finishes low-and-in.
Needless to say, that is a two-seamer with some vicious movement. If a hitter attempted to put that particular pitch in play, it would likely incite a groundball to the right side or perhaps splinter his bat.
In this second clip against Morneau, Gibson tosses his change-up (his secondary pitch against lefties that Seth Stohs’ Twins Prospect Handbook 2011 notes is “above-average”):
 
Like real estate, pitching is all about location, location, location.
With the same arm action as his fastball, Gibson releases a change-up that falls away from the hitter on the outer-half of the plate, down in the zone. In the 2010 Hardball Times Annual, Dave Allen examined how pitch types and their location factor into the success of a particular pitch. What Allen’s research found was that change-ups “are generally successful on the outside edge of the plate or low in the strike zone.” With that in mind, had Morneau offered at the pitch, the likely result would not inflict any damage.
So what we can see in the two-pitch example is a microcosm of why Gibson is so effective against left-handed hitters. In addition to their outstanding movement, a left-handed hitter has to be cognizant of the inside fastball, they also have to be mindful of the change-up away – both of which Gibson has been spotting down in the zone. Given the fact that he can alternate these two pitches effectively, groundballs are manufactured.
Although the rotation is a little cramped right now however with the Twins still entertaining the notion of trading Francisco Liriano and the health concerns lingering for Scott Baker, it’s not hard to believe Gibson’s arrival to Minnesota is imminent.

Will Cuddyer heed his own advice?


When Michael Cuddyer unveiled the team’s new t-shirts with the slogan “Don’t Be Denied”, even though his intention was to motive his teammates through the first round of the playoffs, it’s hard not to imagine that he might have been directing that message at himself too.
A year ago at spring camp, Harmon Killebrew was calling him one of the most powerful hitters on the roster. Considering Cuddyer had just come off of a campaign of hitting 32 home runs, launching 13 of those as “No Doubters which left little question that they would have been out at every ballpark league-wide, it’s not hard to see why Killebrew liked Cuddyer’s power so much. Despite the Killer’s confidence, Cuddyer’s total dissipated to a mere 14 home runs, touching only four of those for No Doubters.
This raised plenty of questions as to where the power had gone.
David Pinto of BaseballAnalytics.org recently took the opportunity to look at the difference between the two seasons and found little variance in opposing pitchers approach to Cuddyer. What his research revealed was a sizeable decrease in power generated from pitches in the middle of the zone.
Inside Edge’s data confirms this. In 2009, Cuddyer exercised a .218 well-hit average on his swing on pitches in the middle of the zone (vertical), considerably better than the league-average of .179. This wound up being the 16th-highest total in baseball that year. That rating would fall precipitously this past year as he posted a .176 well-hit average on his swings for pitches in the middle of the zone, falling all the way to 91st.
If pitchers were not approaching him differently, why did Cuddyer suddenly become anemic to pitches down the heart of the plate? While it is easy to blame the influences of the new stadium, but as Pinto pointed out Cuddyer’s power vanished on the road as well. More likely, the culprit in the case of the missing power can be traced back to his sore knee.
As I mentioned in October a sore right knee could impact his mechanics - certainly causing one to shift weight off of the back leg much sooner than desired in efforts to protect said knee and resulting a diminished capacity to drive the ball. Analyzing his batted ball numbers for the season, we see that as the year progressed, so too did his groundball tendencies. Without being able to lift the ball off the ground, it’s extremely difficult to hit a home run.   
Along the same lines, the knee also likely impeded his ability to pull the ball with authority. Two years ago, when Cuddyer muscled out 32 home runs, he did so because of his ability to turn on the ball with sheer brute force. That year, he amassed a .816 slugging percentage when pulling the pitch to left while dropping off 24 of those 32 home runs into the left field bleachers. This past season, his slugging percentage when pulling the ball dropped to .564 – his lowest total since his injured season of ’08.
Part of the reason the numbers decreased so much was because Cuddyer did not elevate the ball to left field as well as he did in the past:

2006

Cuddyer’s 68.6% groundball rate rates among the league’s more elite slap-hitting, speed machines. The only power hitter to record a higher groundball rate when pulling the ball was the Yankees’ Alex Rodriguez. What A-Rod lacked in pull power, he made up for fishing in dead center as he tagged 12 of his home runs in that direction.
While it is still early in the spring, there are already signs that Cuddyer’s knee may be healing. According to one report, Cuddyer was putting on a display in batting practice, purportedly launching shots far over the left field fence – not unlike his performance in 2009. However, keep in mind spring training is often like being sent to celebrity rehab, many players make strides only to relapse later on.
In order to be successful, Cuddyer needs to regain that edge for turning on a pitch and putting some air beneath it. Not only because Target Field is unforgiving to hitters heading towards center and right-center, but because he has proven he can make pitchers regret working middle-in.

OtB Twins Notes


LaVelle Neal informs us that Justin Morneau, who reported to spring training on Monday, is ready to participant in the team activities but still is not 100%.
While the majority of us would be satisfied with simply having Morneau back on the field by Opening Day, Fangraphs.com’s Jeff Zimmerman collected some research on the 50 players who have returned from the disabled list after a concussion and reviewed their pre-concussion and post-concussion performance.

Zimmerman’s research revealed a notable drop-off in offensive performance – especially in the on-base percentage and slugging categories.

Because the data pool is extremely small, it’s hard to know whether these findings are really indicative of a post-concussion performance. Furthermore, we don’t know if the drop-off incurred was due to the concussion or the time off. After all, any player who spends 60 days away from baseball-related activity will likely experience the same sort of regression. Given Morneau’s description of his symptoms – including fogginess – you can see how one’s on-base percentage may drop when attempting to judge a strike zone through a haze or trying to get a beat on a mind-bending curveball.

In Morneau’s case, back in 2005 when he took a Ron Villone fastball to the dome, he came back strong, hitting .265/.333/.500 in his first 60 games upon his return but finished what turned out to be his worst season as a major leaguer. After missing 81 games last year - in addition to the time off this winter from baseball-related activities - you have to wonder if Morneau is in going to witness a significant drop-off once he returns to action in 2011.
Neal also notes that Scott Baker spent time throwing in the bullpen with little discomfort – only when tossing his changeup.
To me, I do not think Baker is out of the woods for concern over his arm but this is some good news after the initial reports. Baker doesn’t typically use his changeup that often – throwing it 7.5% of the time, mostly to left-handers. On top of that, it is one of his least successful pitches, amassing a career -1.9 runs above average with it and according to Inside Edge, over the last two years, opponents have hit .320 off of his change.

As I noted in the beginning of February, getting Baker healthy again so he can regain the arm angle he dropped in 2010 will likely led to fewer pitches that run astray on him as they did last year.  
The Pioneer Press’s John Shipley tracked down hitting coach, Joe Vavra, and picked his brain regarding Tsuyoshi Nishioka’s swing mechanics. Vavra’s response? It looks good.
Said Vavra:
“I've seen enough on the highlight films and the YouTube and the various different media outlets to know that he's a pretty good hitter. He gets his hands inside the ball well, is able to spray the ball, and it looks like he's able to rotate the ball and drive it."
I’ve taken a couple opportunities to talk about Nishioka’s mechanics this winter and essentially have concluded the same as Vavra. Another interesting nugget provided in the same article was that the Twins do not have their left-handed batting practice arm in camp yet so Nishioka took all his swings from the left-side of the plate.

1500ESPN.com’s Phil Mackey caught up with reliever Anthony Slama who said that he has added a cutter to his repertoire this off-season in efforts to subdue left-handed opponents.

The 27-year-old Slama is a pitcher that appears to be on the cusp of breaking into a full-time relief role. In his four seasons in the Twins organization since being drafted in ’06, Slama has put up attractive numbers working as a closer. In his 249 innings of work, he’s whiffed 345 while producing a 0.4 HR/9 career average leading to a 1.95 ERA. However, while dominant against his right-handed competition, lefties have has some level of success when facing him. Last year in Rochester, righties were limited to a .130 average against with a 2.94 K/BB ratio while lefties hit .242 with a 1.60 K/BB ratio.
Remarked Slama about the cutter:
"That'll be a good pitch for me. I kind of struggled a little bit against lefties. The changeup is a bit of a take pitch for them because they see it early. And typically it'll kind of dive away from them. That's what I'm trying to get groundballs on, and a changeup isn't really a groundball pitch. So I'm hoping a cutter will kind of offset that and give me something to move in the other direction so that the changeup will be nastier."
In his short exposure last year with the Twins, Slama faced twelve lefties, allowing six of them to put the ball in play. Every one of those had elevation as he induced zero grounders.

Reviewing Slama’s limited pitch f/x data on his 4.2 innings at the major league level last year, we see that Slama used his four-seamer/two-seamer combination along with his changeup on the outer-half of the plate which moves away from lefties. Without much available to keep these opponents from diving out over the plate on those pitches, Slama clearly needed another weapon that he could go inside with to keep them honest. If effective, the cutter should then keep lefties from getting solid wood on the change-up, instead beating those into the turf more regularly.   

Mackey’s cohort down in Fort Myers, Tom Pelissero, uploaded a video of the contrast between Joe Nathan and fireballer Jim Hoey while going through their bullpen sessions.
Yup, the ball explodes out of Hoey’s hand. In 2007, Hoey was averaging 95.7-mph for the Orioles while flirting with triple-digits in the minors. Of course, what the clip didn’t show is where the pitched ended up. He’s got the heat but he’s got the wildness too.

I maintain the prediction I made back in January that Hoey has the potential of being a major contributor out of the bullpen this year – provided he harnesses his command and stays healthy. 

Charley Walters, in his infamous ‘Don’t Print That’ section of his column, hints that the Twins are not interested in keeping Danny Valencia long-term.
Since he’s cheap at least through 2012 when Valencia will likely enter his arbitration years, I’m assuming this issue doesn’t mean the Twins will trade him, just progress year-to-year with him until he becomes expensive.

While Valencia emerged as a strong presence at third base – rocking left-handed pitching and fielding his position far better than what had been anticipated – his 322 plate appearances likely do not reflect what his results would be when given a full season. I anticipate some decline in his numbers in 2011 as opponents start to pick through his soft-spots in his swing but expecting his totals to come close to his minor league career rate isn’t farfetched (.298/.353/.469) as he hits breaking pitches extremely well while hitting the ball to the big part of the field often.
Joe Mauer, cover boy for the second consecutive year of MLB: The Show, told reporters that he and some of his teammates actually use the video game as a method for scouting some of their rivals.
You kind of wonder if that sort of a statement is actually part of his duties as the game’s chief spokesman or if the genuinely flip on the game for on-field insight. At the very least, it is infinitely superior to those of Nintendo’s RBI Baseball. Mauer said that the details within the game – specifically, hand placement – is spot-on.  
With scouting companies like Inside Edge, who contributed their stats package to Major League Baseball 2K10, you can see how there is something to be learned from today’s modern games but while this sort of information could be useful in some capacity, accessing video footage of those players should be the preferred method for accurate information.
