http://tinyurl.com/5wkqxs When Kosuke Fukudomo came stateside last offseason, expectations were fairly high. After all, the longtime Chunichi Dragons stud compiled a .305/.397/.543 career line in Japan, winning the league's Central League MVP as well as taking home gold in the inaugural World Baseball Classic in 2006. Intrigued by his broad base of skills, the Chicago Cubs inked Fukudome to a four-year, $48 million deal. While Fukudome’s power numbers figured to take a hit upon transitioning to Major League Baseball, his translated numbers still figured to be pretty lofty. Baseball Prospectus 2008 called the 31 year-old “someone who can get on base at a .390 or .400 clip while contributing in all facets of the game.” PECOTA called for a .289/.401/.504 line, and Fukudome’s most comparable players were promising: J.D. Drew, Jim Edmonds and Fred Lynn ranked prominently on the list. Fukudomania swept the Windy City last spring, as the lefty batter got off to a searing start. He batted .327/.436/.480 in March and April, drawing a Bondsian 19 walks in 117 PA. May was also productive, if less powerful, as he hit .293/.388/.404 with 16 free passes in the same number of plate appearances. As the Cubs entered summer, Fukudome continued to contribute by posting a .264/.387/.402 line in June. It was at the point, however, that the wheels fell off. July was a tough month (.236/.306/.382), but we hadn’t seen anything yet: August brought forth a sickly .193/.293/.253 showing that would make Tony Pena Jr. blush, and Fukudome’s descent continued into September and early October (.178/.288/.289). So, what the heck caused Fukudome to transform him from an on-base fiend to an offensive drag who ended up plastered to the Cubs bench down the stretch? To try and answer that question, I examined Fukudome’s pitch data over the course of the season. I figured that as opposing pitchers became more familiar with Fukudome, they might have discovered a weakness in his game that would present itself in an increase (or decrease) in certain pitches thrown. As it turns out, essentially nothing changed in terms of pitch selection as the 6-0, 187 pounder shifted from Fukudomania to Fukufourthoutfielder. And as I dug deeper into his tale of two seasons, it became apparent that lady luck had an effect on the proceedings. Here’s a look at some of Fukudome’s key indicators over his red-hot start and ice-cold finish: March through June 340 PA 15.5 BB%, 19.5 K%, 20.1 LD%, 50.9 GB%, .133 ISO, .349 BABIP July through October 250 PA, 11.8 BB%, 22.5 K%, 17.8 LD%, 50.1 GB%, .105 ISO, .251 BABIP Sure, there are some differences between the two stretches, but nothing that comes close to explaining the gargantuan shift in performance. Rather, it seems that Fukudome had some pretty awful luck on balls in play from July onward. With each passing month, fewer and fewer ducksnorts fell in for hits: Fukudome’s BABIP by month: April/March: .392 May: .325 June: .317 July: .306 August: .217 September/Oct.: .194 While Lou Pinella seemed to lose confidence in his new right fielder as the season progressed, it doesn’t appear as though Fukudome’s true talent level changed all that much. In all probability, Fukudome is neither the star of April nor the scrub of September. On the whole, Fukudome batted .257/.359/.379 with a refined approach at the plate (13.9 BB%, 20 O-Swing%). His strikeout rate was a little high (20.8%) and his .122 ISO was very tame for a corner outfielder. Luckily for Fukudome and the Cubs, his stellar defensive work (13.4 UZR per 150 games in RF) might mean that he could shift to center, putting less of an onus on his modest pop. Of course, that won’t change Fukudome’s value in the vast majority of leagues, but he is still someone to consider taking a flyer on. Most people will focus on his finish, where he endured a see-a-black-cat, walk-under-a-dozen-ladders unlucky BABIP stretch, but Fukudome could be a good source of OBP in the later rounds. --
