For another point in favor of hitting fly balls, I refer back to Tango and Lichtman?s analysis in The Book of groundball pitcher vs. flyball hitter matchups. Flyball hitters have a distinct advantage over groundball hitters against groundball pitchers. As more teams focus on stacking staffs with groundball pitchers, the importance of hitting the ball in the air becomes more important.

Oakland is already doing the above (Acquiring fly ball prone hitters).

Lots of info in this article.
