However, there are good reasons to think that average is going to be on the way up in the future. Bruce is simply too talented to hit in that range for long, especially in light of the improvements in his approach at the plate. The other reason is purely statistical. Bruce has an extremely unlucky .221 batting average on balls in play (as opposed to a .298 mark his rookie season, which was right around the norm).
How unlucky is that number? It is the third-worst BABIP mark in baseball, behind only Brian Giles and Garrett Atkins, and that's likely to even out over the balance of the season.
