Liriano's rubber shifting

In the bottom of the third inning of Sunday's game against the Indians, Fox Sports North commentator and former All Star pitcher Bert Blyleven appeared mystified by what he thought was a new finding: Francisco Liriano was switching his location on the rubber contingent on whether the hitter was left- or right-handed.

During Shin Soo Choo’s at-bat, Blyleven released this nugget: “To be honest with you,” Blyleven confided with the viewers in the third, “I’ve never seen Liriano going to that first base side of the pitching rubber. He’s usually on the third base side…maybe he’s shifting with left-handers and right-handers…we’ll keep an eye on that.”

Following Choo was the right-handed hitting Austin Kearns. Blyleven then noted that “now Liriano, with a right-hander up, you see he’s moving on the pitching rubber…”

“How about that?” Interjected Dick Bremer.

“…over to the third base side.” Blyleven allowed a pitch to pass then added, “You don’t see that too often where a pitcher will move one side [of the rubber] to the other.”

In the ensuing bottom half of the fourth the broadcast threw up a split-screen graphic depicting Liriano’s approach to the left and right-side of the lineup. This was followed by Blyleven’s admission “I didn’t notice that in the other starts for Liriano…maybe it’s something he and Rick Anderson, the pitching coach, have been working on.”

Congratulations. Blyleven may have stumbled upon a discovery that has been an occurrence for the southpaw since '08. According to pitch F/X charts, Liriano has used this approach dating back to his return from Tommy John surgery:

In ’08, Liriano’s release points varied from slight over a half-foot to two-and-a-half feet to lefties but ranged from dead-center to slightly under two-feet to righties. Meanwhile, in this past season, there was stronger visual evidence of this shift:

Last year, Liriano worked the lefties from well-over the half-foot mark to almost three feet away from the middle of the plate. This shows more of a movement down the rubber towards the first base side in the event of left-handed foes. Likewise, his approach to righties were the same as his '08 year -- in spite of some very unfavorable results. Essentially, he kept his positioning static on the third base side and had a release point between dead-center and two-feet to the left of the plate. Here is video evidence of Liriano working to lefties on the first base side then to righties on the third base side in ’09.
As pitch F/X shows in 2010, all of his release points to lefties have been at a foot-and-a-half to two-and-a-half feet to lefties. Instead of working from the middle of the rubber like he had in the past to some lefties, he is consistently staying at the first base side. This has worked extremely well for Liriano as lefties were hitting 2-for-23 (.087) against him in his four starts heading into Sunday’s game. 
 

So for the past two seasons (possibly longer if we could find reliable '06 data or video), Liriano has transitioned up and down the rubber. This is hardly a new development and definitely not something Anderson and him have concocted this season. Still, in Blyleven's defense, while Liriano at times worked lefties from the middle of the rubber in the previous two seasons, this year he has remained consistently on the far left-hand side of the rubber. 

This emphasis may have made him that much more unhittable to same-sided batters as Liriano's ground ball rate has skyrocketed in this young season comparative the the past two:

Liriano vs LHB:GB%OPS
200856.6.637
200953.3.637
201070.0.233


Despite what Blyleven would levy on air, Liriano has been moving up and down the rubber regularly since ’08. What is different in 2010 is that he appears to be moving to the first base side against ALL lefties and has avoided pitching from the middle as he did in the previous two seasons, which is working extremely well for him so far.

Denard Span has been grounded

Minnesotans have quickly grown fond of Target Field. You can include Florida-transplant Denard Span in that category as well.
 
While at the new stadium, the Twins center fielder has amassed a .367/.537/.467 batting line in just 41 plate appearances while hitting a home-sickly .154/.237/.212 in 61 plate appearances away from Target Field. After Span opened the year with a 4-for-28 (.142) start in Anaheim and Chicago, his road split was even further exacerbated on the most recent tour of the country as the leadoff man has once again gone 4-for-28 (.142) since the Cleveland series at home concluded.
 
Without question, Span’s absence from the offense is detrimental and has been a reason why the Twins have split the six games between the Royals and Tigers. In the nine games at Target Field, Span averaged a run per game but due to his truancy from the base paths, he has scored just one run in the past six. Not surprising, the Twins gone from scoring 5.4 runs per game in the homestand to scoring 4.6 runs in Kansas City and Detroit (still above average but a drop-off nonetheless).
 
Even though the home/away splits might suggest Span isn’t happy with spending his nights at the Holiday Inn Express in Overland Park, his lowly road numbers appear to be the consequence of a suppressed BABIP in general. After putting together consecutive seasons of producing significantly higher BABIPs than the average, he is experiencing the inverse this year – his .264 BABIP is far below the .287 league norm. This digression from his career norm is a product of an increase in ground balls and their subsequent conversion into outs:

*Data from Fangraphs.com and Baseball-Reference.com
In his first two seasons at the major league level, he had hit around 53% of the total balls in play on the ground. And up until this year, it has work for the speedy Span. In addition to finding more seams in the defense, he also legged out 23 infield hits (10th most in baseball) to supplement his numbers. This year, his ground ball rate is the third-highest in baseball (behind only Derek Jeter and Michael Bourn). At the same time, the inflation in his ground ball output has come at the expense of his line drive rate, which has plummeted to a career-low 13%. So not only has Span experienced the bitter pains of batted ball hard luck, he’s also not producing the trajectory type that typically winds up as hits 70% of the time. It is quite the double-whammy.
To be sure, there has been nothing wrong with his fundamental approach in 2010. Span has added great value through his patience at the plate, as his keen zone acumen has resulted in a copious amount of walks (16). This has led to a .360 on-base percentage heading into Thursday’s game. In all, his 2010 plate discipline numbers are on par with the rest of his career meaning he isn’t suddenly chasing after bad pitches or missing more than usual. Likewise, his well-hit average of .207 is in line with the league average (.208) so he is putting the ball in play solidly.
With a very good comprehension of the strike zone, quick wrists and strong ability to make contact, Span’s overall numbers are tied to the current fortunes of the bouncing ball.  As the batted ball numbers begin to correct themselves over the course of a larger sample, he should regain his status as one of the lineup’s main run contributors.

How ridiculous is Liriano's slider?

Last night, Fransico Liriano worked through the Tigers lineup like a buzzsaw, using his slider to retire 10 of the 28 opponents he faced - six of which were on strikeouts. There were buckling knees and stupidly silly swings as the slider appeared to race up to the edge of the plate and diving off the table. The only mistake was a slider left up that Johnny Damon laced for a double but aside from that one transgression, Liriano was nearly flawless in Motown - as he has been for the past 23 innings. 
 
Through four starts, Liriano possesses perhaps the game's best slider. Judging from the weighted run value at Fangraphs.com, his 6.55 wSL/C is the tops among starters. Likewise for his Opponent OPS on the pitch found at MyInsideEdge.com:

In general, his results on the slider have been much better than that of the previous season:

While there are several reasons for his overall turnabout, including an improved command of his fastball and working ahead of hitters, his rekindled slider has been his strongest offering thus far. Opponents are offering at more pitches out-of-zone and missing at a higher rate which has led to more strikeouts. His chase rate on the pitch is the highest in baseball (minimum of 100 pitches thrown) as is his miss percentage. To summarize, this is a bar whore of a slider: just all kinds of dirty.

What makes this version so much different than a year ago? In 2009 Liriano was throwing his slider at a higher velocity. This translated to just a 5.5-mph difference with his fastball. With his increased fastball velocity in 2010, he's also toned down the MPH on his slider, decreasing the velocity on that pitch by 2-mph. This has led to a near 10-mph (9.1) separation in his fastball and slider.
 
What's more, Liriano has added more drop to his slider. As you can see in the column above (Vert.) and visually in the graphs below, the Twins lefty is getting more decline out of his breaking pitch:
 
*Data from TexasLeaguers.com - 2009
 
*Data from TexasLeaguers.com - 2010

With everything clicking on all cylinders, it is likely that Liriano and his dirty slider will increase his scoreless inning streak in Cleveland against one of the most offensively-challenged lineups in baseball (scoring just 3.55 runs per game).

OtB's Around the Central (04.27.10)

Chicago White Sox | 8-11 T-3rd | 5 games back
  • First baseman Paul Konerko hit his league-leading 8th home run of the season on Monday and his third in as many games as the Sox won their third straight against Seattle. 
    • ANALYSIS: No matter how hard they try to build a team to reflect "Ozzie Ball", they still seem to gravitate towards the long ball. As it stands, their 26 team home runs is currently second behind the Blue Jays (28) but the majority of bombs have been of the solo variety. Still, while Twins fans worry over clutch and timely hitting, the White Sox are mired with a .143 average with runners in scoring position in the past 10 games to go along with their baseball worst .222 overall batting average. 
  • Ozzie Guillen believes that Sergio Santos, former Twins farmhand turned reliever in the White Sox organization, has the chance of being the team's closer someday
    • ANALYSIS: The "salvage" project has yet to allow a run in 8 innings of work. Thus far, he's been one of the dirtiest relievers in the game - his 57.5% contact rate is the fourth-lowest among relievers in all of baseball. Santos is hitting 95.5-mph on average and supplements that with a slider/changeup combination that has worked very well for the 26-year-old. Armed with those three plus pitches, Santos could easily usurp the incumbent closer Bobby Jenks who is eligible for his final year of arbitration in 2011. Although there are discussions regarding Santos transitioning to a starter's role, the righty has little designs on moving from the back-end of the bullpen where he prefers to remain
  • With a .355 OPS, catcher AJ Pierzynski remains one of baseball's least productive players in the early going of the 2010 season. In his past 25 at-bats, Pierzynski has coax just a solitary hit off of Tampa's David Price a week ago Tuesday. 
    • ANALYSIS: The 33-year-old catcher seems to be the recipiant of some horrendous luck. While putting the ball into play regularly on line drives similar to his career rate (21.2% LD%), Pierzynski hasn't had many fall in for hits as his .154 BABIP is the fourth-lowest in baseball. These two numbers would be indicative of a impending turnaround. Never one to walk or strikeout much, Pierzynski has been seeing an extremely high percentage of fastballs (71% FB) but has failed to hit them solidly (.140 well-hit average versus a .204 league-average).  

Cleveland Indians | 8-11 T-3rd | 5 games back
  • On Monday night, the Indians were 1-for-11 with runners in scoring position and left 14 men on base in the 5-2 loss to Anaheim. 
    • ANALYSIS: While no one really anticipated much from this lineup, with Grady Sizemore returning after an injury-riddled 2009 season, there was optimism that the young team would be able to improve. Currently, the Indians exercise baseball's worst average in baseball (.223), the worst RISP average (.205) and, unlike the White Sox who have compensated with the long ball, Cleveland's 14 home runs is tied for third fewest in baseball. All of this has led to just 62 runs scored - tied with Baltimore for the fewest in the American League. 
  • After throwing in a simulated game in Oakland, injured closer Kerry Wood is gearing up for his rehab assignment"I don't know how long it will take," said Wood. "At this point I'm not putting any number of days on it. I'm just going to go and come back when it feels ready to go."
    • ANALYSIS: Wood's simulated game didn't go so well. The Cleveland Plain Dealer reports that he was unhappy with his performance and that it may signal a significant step back in his return to the majors. Interim closer Chris Perez has been 4-for-5 in his save opportunities in Wood's absence but is fairly raw in his abilities. Though he might be the closer of the future, his nasty 3/6 K/BB ratio is far from the closer echelon and he has fallen behind hitters far too frequently (40.6% first-pitch strike). The Indians need to get Wood back on the field in order for him to make a few appearances to inflate his trade value enough to unload his massive contractual obligations on some other unsuspecting team. 

Detroit Tigers | 11-9 2nd | 2.5 games back
  • After his first four starts, Justin Verlander is 1-1 with a 6.95 ERA and 19 strike outs in 22 innings pitched. 
    • ANALYSIS: Starting out slow is nothing new for Verlander. Last year through his first four starts the hard-throwing righty was 0-2 with a 9.00 ERA. The year before that? In '08 he started 0-3 with a 7.03 ERA. In general, Bill James found that power pitchers struggle a bit more at the beginning month of the season so Verlander should turn it around quickly. At the same time, Verlander did log 240 innings (most in MLB) and threw over 120 pitch in 11 of his outings while averaging 112 pitches per game. It is quite possible that there will be signs of toll on his arm in '10. Verlander's fifth start doesn't get any easieras he faced the Twins: Thome, Morneau and Mauer are a combined 33-for-108 (.305) with 12 HRs.  
  • Like Verlander, sophomore starter Rick Porcello is also in the midst of a rough patch in the season's opening month. Through four starts, Porcello is 1-2 with a 7.91 ERA and 13 strikeouts in 19.1 innings of work.
    • ANALYSIS: Porcello's actually thrown very well. He's getting ahead of hitters (58.7% first-pitch strike) and getting more groundballs (56.3% GB) while avoiding solid contact (12.7% LD rate down from 17.1% in '09). So what's the youngster's problem? His .449 BABIP is weighing him down (the highest in the AL). Behind him, the defense is failing to convert balls in play into outs -- especially his grounders. Opponents have a .415 BABIP on earth-scorchers when the league average has been at a .207 BABIP. With his strong batted ball numbers, his BABIP should begin to equalize over the next four starts. 

Kansas City Royals | 8-11 T-3rd | 5 games back
  • Following Sunday's 4-3 win over the Twins, manager Trey Hillman was asked if the combination of Dusty Hughes, Josh Rupe and Joakim Soria was the right combination to ensure protect leads. Hillman replied no and said that lefty John Parrish, who allowed a game-tying home run to Justin Morneau on Saturday night, has one of the best lefty-on-lefty breaking balls among his internal options
    • ANALYSIS: The bullpen has been atrocious, that's for sure. Their 6.38 ERA is the worst in the American League by almost a run. While the personnel hasn't been elite for Hillman, part of the blame rests squarely on his shoulders. A quick check of the numbers reveals that Hillman's statement isn't quite true. Left-handed opponents are hitting just .125/.333/.125 with a .250 well-hit average off of his breaking stuff while Parrish's breaking stuff has been thwacked to the tune of .375/.500/.750 with a .375 well-hit average. 
  • The Royals claimed Jai Miller who was released from the Oakland Athletics organization.
    • ANALYSIS: The right-handed hitting Miller is an extremely strikeout-prone hitter (237 in 884 plate appearances since '08) that has some pop (35 HR the past two seasons). While he is a .236/.320/.386 career minor league hitter, he has hit .270/.347/.473 in AAA. He's an insurance policy in the event that Rick Ankiel is unable to recover quickly and will likely fill out Omaha's roster.

Time to shave the beard?

As the rest of the Twins lineup is busy producing runs like a taco stand serving tainted meat, Jason Kubel has been inauspiciously quiet. Since the home opener the left-handed slugger has had fewer hits than Chumbawamba, going just 3-for-29 (.103) with nine strikeouts.

On Wednesday, I showed that part of the reason for his slump is because pitchers have noted his insatiable appetite for meaty fastballs and have switched his diet to low-fat and tasteless sliders and curves. The results are fewer pitches in the strike zone and ultimately fewer pitches he can feast upon. Kubel has displayed restraint in most cases – drawing more walks and chases after out-of-zone pitches less – by largely ignoring the servings of non-fastballs and off-the-plate appetizers. 

Yet in order to stop his batting average from slinking towards a number typically reserved for describing a Brewers fan’s blood alcohol content, Kubel also needs to stop hitting them directly at people. There are signs that the defense's good fortunes might not last much longer. For one thing, is batting average on balls in play (or BABIP for shorthand) is absurdly low. As a rule of thumb, if this number is well-below or towers above the league average, there is a strong indication that a player is primed for improvement or regression. In Kubel’s case, the lefty is sporting a BABIP (.226) as ugly as his beard – and far below the league average (.291) in addition to his own career mark (.303). 

Meanwhile, considering the method in which he is putting the balls into play, we can easily deduce that he is hitting the ball square. In Kubel’s 56 plate appearances before Thursday’s game, he has hit 27% of his balls in play as line drives. This is an extremely positive total. In general, line drives fall in for hits far more often than grounders or fly balls. Last season, liners became hits 72% of the time while grounders did so 24% of the time and fly balls just 13.4% (with the exception of home runs which are not considered “in play”). The natural conclusion is that if his line drive totals are up, the batting average will eventually correct itself as line drives find vacant real estate. 

But not only is he hitting line drives regularly, he’s hitting everything solid. Behind Inside Edge’s pay wall is a fairly underutilized statistic that may assist in bridging the gap from the “assumed” (i.e. high line drive rate coupled with low BABIP equals bad luck) to the “actual” (i.e. genuinely screaming balls around the field off his bat). Like Baseball Info Solutions, who gathers all of the batted ball data that we find at Fangraphs.com, Inside Edge has added a little extra flavor by denoting if the ball – be it grounder, liner or fly ball - was well-hit. The Well-Hit Average (well-hit balls/at bats) provides us with another metric to gauge the type of contact, regardless if it was hit land, air or sea. While the rest of the league holds a .208 well-hit average, Kubel has exercised a very good .239 well-hit average. 

If he continues to spray shots around the ballyard at the same rate, there is no reason not to expect a full turnaround long before summer begins. 

However, if this decline continues on the road trip, the next step is to shave the beard.
