Batted Ball Location Leaderboards
My first post on this site in February borrowed the main idea of Dave Studeman's batted ball reports, except instead of looking at the trajectory of batted balls, I grouped them by vector. A full season has passed, so who were the best pull hitters in baseball this year?
Value of Pulled Batted Balls
I think part of the reason that Youk and Jason Bay are listed is that they play get to take advantage of the Green Monster. I'm not trying to discredit them, since they're both excellent right-handed hitters, but I am trying to discredit Dustin Pedroia and Mike Lowell. Here is the average run value of pulled fly balls and line drives for Boston's four main RHBs since 2008.
Lowell pulls half his balls in play, too, so I doubt there's any park that he'd rather play in than Fenway. As for Pedroia, he has a career .332/.391/.505 line at home. On the road, he hits .283/.350/.406. He has never hit a 400-foot home run in his career according to Hit Tracker. I doubt anybody is more suited for his home park than Pedroia is for Fenway.
At the bottom of the list is Casey Kotchman, who I believe is the only first baseman to have totaled a negative value on pulled balls. Over a quarter of Kotchman’s balls in play were pulled groundballs, and he hit .073 on those. In 2008, a whopping third of his balls in play were pulled grounders, though he managed to hit .154 on them, so it's possible defenses have figured him out.
Value of Center Field Batted Balls
Ryan Howard focused his prodigious power to center this year. Previously, Howard hit the plurality of his home runs the opposite way three times in his career, and in 2007, he had pulled the highest share of his homers, but this year, he hit a remarkable 21 of his 45 homers to center. Mark Reynolds came closest to matching Howard with 17 home runs to center.
Value of Opposite Field Batted Balls
Only Adrian Gonzalez hit more opposite-field homers than Joe Mauer this year. Adrian Gonzalez in Fenway Park would be scary. Derek Jeter, who’s always had opposite field power, hit the most home runs to right field batting right handed this year, possibly rejuvenated by the even shorter short porch at the New Yankee Stadium. In 2008, Jeter had better luck going the other way with his fly balls when he was on the road than he did when he was at home. That split did not continue in 2009. Jeter produced slightly better results on flies to right in the New Yankee Stadium than he did while playing on the road.
Jimmy Rollins' batted ball profile continues to perplex. He hit an anemic .200 on grounders this year, below his already mediocre .231 career average. Though speed is important for batters to reach base safely on grounders, spraying the ball to all fields might be even more weighty. Rollins hit only 7% of his groundballs the other way, which allows defenses to shift their fielders to one side of the field, and signifies that he's rolling over on the ball when he hits grounders. Placido Polanco, Jermaine Dye, and Joe Crede all hit over a third of their flies to the opposite field, but under 5% of those balls fall for hits.
A spreadsheet containing the full results can be found here. Batted ball location data via MLBAM. The field was partitioned equally into thirds to classify right/center/left.
