How about that Jim Thome fella?

Now that the season’s almost done, I can finally bring myself to admit it.

I was wrong about Jim Thome.

Back in January, I took a cautionary stance on the signing of the designated hitter. While he still had the same eagle-eyed approach at the plate, the biggest reason I urged people to exercise caution on the Thome acquisition was that his ability to pull the ball last year had completely evaporated. To me, this suggested age and injuries had taken a toll on the big slugger’s body and that it was just a matter of time before he would become just bench-filler.

In 2009, just a handful of Thome home runs left the yard on the right side of the field, his lowest mark of his career. At 38 years old and a track record of back injuries piling up, it was easy to associate this with an overall decline. Needless to say, Thome’s symbolic shot off the flag pole deep in right field on Monday afternoon sent a clear message: Jimmer’s is just fine.

This season, the now 40 year old Thome has been able to generate power once again to the right field portion of the ballpark, launching seven home runs in that direction as well as producing a .769 slugging percentage:

Jim Thome’s Pull Power
Season	Pulled HR%	Pulled SLG%
2008	41%	.685
2009	17%	.520
2010	33%	.769

Not long ago, in a recent Sunday Night Baseball broadcast, commentator Joe Morgan also echoed this sentiment about Thome’s inability to pull the ball. Morgan said that he noted last season that Thome’s bat speed was slowed and thus was unable to turn on an inside pitch. In Morgan’s view, Thome was in the twilight of his career when playing with the Dodgers.

In a rare occurrence of a blind squirrel finding a nut, it appears that Morgan was right. According to Inside Edge’s database, Thome had not handled anything thrown inside particularly well the previous two seasons, posting well-hit averages below the league’s average.

Of course, like almost everything else Morgan usually says, it was proven to be false. Thome is absolutely destroying anything that flies within that inner-half of the plate:

Jim Thome and the Inside Pitch
Season	Well-Hit Average (Inside)
2008	.056
2009	.052
2010	.133
MLB Average	.078

Overall, Thome’s power has had a remarkable rebound. Research showed that his power was slowly decreasing as his isolated power (slugging minus batting average) numbers had fallen from .287 in ’07 to .258 in ’08 to .232 in ’09. This was yet another indication that Thome was potentially slowing down. Clearly, Thome has proven the critics (and, without a doubt, me) wrong there. In just a shade under 300 plate appearances, Thome has produced a .346 isolated power – his highest since 2002 when he was still in a Cleveland Indians uniform.

Whatever the reason might be behind this resurgence – health, exercise regiment, coaching – Thome’s been able to rediscover the approach that has made him feared by opposing pitchers. He's been a blessing to this lineup and the Twins should consider themselves fortunate he fell to them this past offseason. 

Blackburn changes things up

In the middle of July, mired in a five-game stint in which he had allowed 28 earned runs in 22.2 innings pitched, Nick Blackburn was desperately in need of some re-tooling. The problem was fairly evident: he simply was not changing speeds enough. 

This was something that pitching coach Rick Anderson encouraged as far back into the season as June. At that time, opponents were slaughtering his fastball. Even with the mounting evidence and direction from his coaching staff, Blackburn stuck to his two-seam fastball that continued to be belted across the universe.

Now, after Saturday’s 1-0 victory over Seattle, Blackburn has made two consecutive quality starts. In those outings, the righty has worked 15.2 innings, allowing 10 hits while striking out 11 and walking two. This resurgence, notes La Velle E Neal, stems from Blackburn rekindling his relationship with the changeup, “tinkering” with the pitch in his starts in Rochester.

Looking back at his pitch usage, the data confirms that he has used the changeup more frequently since his recall:

Blackburn’s Assortment:	Fastball	Changeup	Curve
8/28 @SEA	58	28	11
8/23 @TEX	61	20	9
7/28 @BAL	20	6	7
7/18 vs CWS	50	11	10
7/10 @ DET	53	4	5

Said Blackburn after this past weekend’s near complete-game, shutout against Seattle: 

"Joe [Mauer] and I had these guys off balance, and they just weren't putting good swings on the ball. I was throwing pitches down the middle and they were looking for something else, and it was good. It was fun.''

Essentially, this was the byproduct of changing speeds better. As I stated back in July: 

“If you miss your spots, as Blackburn has done so routinely recently, the damage may be minimized by messing with the hitters’ timing. If you are missing spots and throwing at the same speed constantly, professional hitters will hammer those pitches. While location remains supremely important, if there is a deviation in velocity or break, this may incite hitters to commit too early to a pitch they would otherwise drive, turning it over on the ground. When Blackburn was tearing through opponents in May, he rarely showed the same reliance on his fastball in succession.”

In order to continue this success into the fall, Blackburn needs to commit to varying his speeds consistently. Good start so far.

Tonight: Span or Repko in center?

Today, I assisted Fangraph.com's Carson Cistulli in answering the question: Who should start in center, Denard Span or Jason Repko? 


For this particular instance, I favored Repko over Denard. Certainly with the Rangers starting the left-handed killing machine in CJ Wilson combined with Span's need to readjust his approach, today merits the opportunity to give the starting center fielder a night off.


However, there is a contingent of voices in Twins Territory that are crying for a more permanent switch. Because of Repko's defensive prowess and sudden offensive surge in his limited capacity, there has been rumblings to bench Span in favor of Repko altogether. This, of course, is absurd.


Admittedly, Span is in need of some respite, as he has been flummoxed by opponents who have altered their approach by firing strikes early in the count when data/scouting showed Span didn't swing. Repko, while playing effectively in small doses, does not have nearly the same skill set that an effective Denard Span has when it comes to leading off. The right-hander manages to strike out in over 25% of his big league plate appearances leading to a .300 OBP in his career. That just won't cut it in the lead off spot. The Twins need Span's presence at the top of the order and they need him to make adjustments quickly.

OtB Twins Notes

With Kevin Slowey hitting the disabled list, Nick Blackburn will make a start tonight for the Twins. There are some indications that Blackburn has rediscovered his scorched earth policy in Rochester that made him so effective in ’08 and ’09. In 23 innings at AAA, Blackburn has amassed a healthy 65.3% ground ball rate according to minorleaguesplits.com. Unfortunately, in his most recent start, Blackburn allowed five run (four earned) in 5.1 innings of work.

With Ron Mahay now sidelined with a shoulder injury suffered on his non-throwing arm, the Twins are now down to one left-handed option in the bullpen: Glen Perkins. As Nick Nelson commented last week, Perkins is far from an ideal candidate to assume this role as his career numbers do not necessarily reflect a pitcher that is dominate against same-sided opponents. While I agree with the stance, there are some signs that Perkins might be able to navigate some of the situational appearances adequately. Yes, his peripherals are not strong – a weak 4.7 K/9 versus LHB in AAA this year combined with inept career numbers isn’t reassuring – yet this season Perkins has been able to keep left-handers on the ground more often than not (he’s got a 51% ground ball rate). His hefty .327 batting average against the southports may have some to do with a suspect infield defense and his results may be better with the Twins’ high-quality middle infield. If the Twins do decided to push forward without any additional help as Phil Mackey alludes to, things may get dicey against upper echelon left-handed hitters.

Upgrades are certainly available in this area.  La Velle E Neal noted that the Dodgers’ George Sherrill and the Blue Jays’ Brian Tallet have both cleared waivers and can be traded to anyone before the August 30th waiver deadline. Of the pair, Sherrill is by far the more attractive option when it comes to facing left-handed opponents. Although his control has been extremely unreliable this season (as evidence by a 5.52 BB/9 this season), the Dodgers lefty is very tough on same-sided opponents. According to MyInsideEdge.com’s figures, Sherrill has the second-lowest well-hit average (.093) as a left against his compatriots this year. So, while his numbers against righties is grotesque (.418 batting average, 10/5 BB/K), he has fared much better against lefties (.191 batting average, 8/11 BB/K). Given the current ownership situation and 11-game deficit in the standings, the Dodgers may be interested in unloading Sherrill. However, Sherrill could also be an expensive proposition considering his contract of $4.5 million even prorated would be a high expense for someone who would be used in limited capacity for the remainder of the season.

Speaking of late season maneuvers, Sid Hartman implores GM Bill Smith to work his stuff in evaluating talent similar to what he did last year. Unfortunately, he does so beneath a very suggestive and borderline inappropriate headline: “GM’s magic wand is needed again”.

During Saturday’s broadcast, Jose Mota and Dick Bremer were discussing Jason Kubel’s towering blast on a hanging breaking ball thrown by Danny Haren from the previous game. Mota, a Fox broadcaster who had worked with the Angels broadcast team for year, noted that the Angels game plan when facing Jason Kubel was to avoid throwing him breaking balls. This, of course, seemed odd to me. For anyone who follows the Twins on a regular basis knows, breaking balls have long been Kubel’s kryptonite in the past. However, research shows that in the past 30 days, Kubel’s been lighting up the soft stuff, slugging .765 on curves and sliders. This sort of production against the slide pieces and benders should lead to an increased amount of fastballs to hit, something that opponents had tried to restrict at the beginning of the season.

Denard Span made an appearance on Thursday’s broadcast of the Reusse and Mackey Show on 1500ESPN. Span, whose walk struggles I documented on the previous Friday at TwinsCentric, was asked by Phil Mackey why the walks have vaporized. Span’s conclusion essentially mirrored what I laid out on Friday: Pitchers were starting him off with more strikes and setting him behind in the count. On Saturday, Span echoed the same to La Velle E Neal, telling reporters that "The way they are pitching me, the word is out that I usually take the first pitch and I've been watching strike one right down the middle. After that, then I'm getting the whole kitchen sink thrown at me.” With this in mind, be ready to see Span swinging more frequently early in the count.

One of the biggest assets that the Twins acquired this offseason at a minimal price was outfielder Jason Repko. Not only has Repko provided the Twins with superb defense in a pinch, he’s also generated some pop, slugging .508 in 69 plate appearances, hitting six doubles and three home runs. From the Great Falls Tribune, the city in which Repko’s professional career begin, is a good piece on the role player.   

Remember 2006’s spot starter Mike Smith and his glorious mane of hair that flowed out the back of his cap about two decades too late? You know, the guy that looked like he came rocking up to the stadium in a TransAm blasting Sister Christian? No, well, he only made a brief three inning appearance in Kansas City finishing the afternoon with three walks, a hit batter, a home run allowed and a 12.00 ERA in a Twins uniform. Sure, he’s a minor footnote in the Twins lore, but apparently, he’s a legend in the Can-Am League (the place where Eric Gagne went to die), currently tied for lead-league in wins (11). 

Behind Mauer's second-half surge

In the first-half of the season, Joe Mauer turned in numbers that were unbecoming of a reigning MVP. He still maintained an above average walk rate and continued to spit out line drives out like sunflower seed shells however, the numbers just wouldn’t cooperate.

He checked into the All Star Break hitting  .293/.368/.434 (792 OPS) – slashes that were significantly below his career norms coming into the season. Since his low point (one which would be the majority of player’s career years), Mauer’s been wildly successful in the season’s second act. From July 15th on, he is hitting .442/.504/.681 (1.185 OPS) and has been a main catalyst in the team’s resurgence.

What has been the driving force behind this incredible hot streak?

When the going was tough, various analysts and speculators alike threw out plenty of explanations ranging from lingering injuries to pitchers changing their approach to positioning of the defense that had adverse effects on Mauer’s overall totals. It appears that all three played a partial role in his downsized totals, but it is most likely that the last factor has been the most influential.

Some observers suggested that Mauer was no longer driving the ball as well as he had in previous seasons, which was attributed to his various physical ailments. Nevertheless, using the Inside Edge-collected Well-Hit Average, we find that not only was he still hitting the ball with authority, he has been leading the league in this scouted statistic this season. In fact, he has shown more plate coverage than an episode of Man v. Food:

Zone	Mauer’s Well-Hit Average	MLB Rank	League Average
Inside	.189	1st	.080
Middle (Vert)	.246	9th	.159
Outside	.251	1st	.095
Up	.243	1st	.103
Middle (Hor)	.269	2nd	.136
Down	.174	1st	.087
Overall	.395	1st	.214

With his long arms and sugar-sweet swing, Mauer has given pitchers little areas of the strike zone to aim at without experiencing repercussions. Regardless of what the pitcher decided to throw (fastball, changeup, slider, kitchen sink, et al) and where, he was pasting pitches all around the field and yet, for a substantial portion of the year, he did not reap the dividends of doing so.

This is where the defensive alignment comes in.

As a hitter with a high percentage of ground balls, Mauer padded his batting average by sneaking numerous bouncers through the infield in 2009. Last year, he hit .288 on ground balls (65-for-226) while the rest of the league floundered around the .230 mark. Mauer particularly thrived at muscling grounders up the middle, hitting .632 on worm-burners in that direction (that’s over 60% of total balls in play becoming hits). Visually, we find that his spray charts reflect that the middle of the diamond was left unguarded last season:

Opponents had figured out his tendency when it came to these batted balls. Like most everything else, astute teams paid attention to this detail and fortified the midsection of the infield a bit more thoroughly in 2010. Suddenly, that escape route for grounders was no longer a viable option:

As you can obtain from the spray chart above, numerous would-be hits were thwarted near the keystone as teams shifted their shortstops and second basemen to squeeze the middle. While still scorching ground balls, Mauer did not get the same type of results he had the prior year. With this option removed Mauer’s average on ground balls took a decisively raunchy turn as the Twins catcher went 26-for-114 (.228 BABIP) on all grounders in the season’s first-half.

Perhaps partly due to the laws of regression and partly due to his own adjustments to the defensive shading, Mauer’s ability to record hits on grounders greatly improved. Assisting in raising that batting average back above .330 is the fact that he is able to achieve hits by way of land once again: Post-All Star Break, he is 19-for-48 (.395 BABIP) on ground balls.

To some extent, the same can be said about his line drive figures as well. While he was buzzing liners around the field at a .781 BABIP last year, a substantial number of those found their way to the awaiting defense this season as teams positioned themselves to expect drives to left field. Although opponents may shift the outfield around to accommodate for his opposite-field line drive tendencies, his ability to hit the ball solidly to all fields eventually resulted in clean hits which we have seen the past two months.

While battling injuries and still hitting the cover off the ball, Mauer had to solve the defense that continued to beat him in the first-half of the season. His second-half has certainly been remarkable thus far, but the Twins would benefit from an equally strong finish from their franchise player to keep their stranglehold atop the AL Central.
