Regardless, it's always interesting to see how players do in and out of their home park. Conventional wisdom relates that players hit better at home than they do on the road and the MLB splits verify this: in 2007, major league batters put up a .772 OPS at home and a .745 OPS on the road. That's a pretty decent separation.
Let's look at the individual hitters who hit better at home and who hit better on the road. We'll use OPS as the statistic of comparison because it's easy to calculate and pretty useful. The minimum number of total plate appearances might be kind of contentious, but I'm going to pick 300 both because it's a fairly high round number and it breaks up our list into two convenient chunks (what luck!). Twenty-five batters had an OPS at least .200 higher at home than on the road and fifteen had an OPS at least .200 higher on the road than at home.
Largest Difference In Home/Road OPS for 2007
Batters With a .200+ Higher OPS at Home
|Tony Pena Jr.||KCR||268||.335||.442||.777||268||.234||.271||.505||536||.101||.171||.272|
Batting Average on Balls In Play (BABIP) is a statistic that measures the amount of hits that fall in. It's formula is (H-HR)/(AB-K-HR+SF); as I'm sure you can tell, by taking out home runs and strikeouts you are left with the at bats where the ball was put in play for the defense to field. Originally applied to pitchers wherein a pitcher with a really high or really low BABIP likely is due for a regression, it can also kind of be used to see if a batter is lucky or not.
Oddly, Juan Uribe's BABIP actually went up when away from US Cellular Field. Since that means more hits were falling in on the road, you'd think his stats would have gone up when on the road. He was the only player to see his BABIP increase; Scott Hatteberg had the largest drop with his BABIP going from .393 at home to .244 on the road.
As I mentioned before, fifteen players had the opposite change in their OPS.
Batters With a .200+ Higher OPS on the Road
|Wily Mo Pena||BOS/WSH||159||.296||.293||.588||158||.342||.577||.919||317||.046||.284||.330|
|Paul Lo Duca||NYM||243||.263||.310||.573||244||.361||.450||.811||487||.098||.140||.237|
There aren't really any fluky BABIP stories here. The smallest change was an .019 increase from home to away for Brian Giles and the largest was Luke Scott's .128 jump.
For the curious, the most "even" player in the league in terms of a home/road split in terms of OPS was Greg Dobbs of the Philadelphia Phillies. He hit .275/.324/.456 at home and .268/.335/.444 on the road for a slim .00076 difference in his home (the better one) OPS and road OPS. If, however, you envision a plot of OBP and SLG with OBP on the x-axis and SLG on the y-axis and take the magnitude of the vector that goes to each player's point, you find that Jarrod Saltalamacchia was the closest to having no change. His OBP on the road was .00142 higher than at home and his SLG was .00324 higher at home than on the road.
