A popular stat for fantasy baseball owners over the last decade is BABIP (Batting Average Balls in Play). I can't stand this stat as I believe it has no value. Each player in baseball has their own skill-set and baseline for BABIP. Just like batting average, this stat is going to have a wide range from season to season for each player. What looks suitable for one player in one season may be bad for another player in the same year.
The bottom line for me is that if a player hits the ball hard, he will get more hits.
