I’ve had a couple of people ask me to explain this in the past few days, so I figure there must be interest in the question: Robinson Cano of the Yankees is presently batting .327 with a .320 on base percentage. For those of you wondering how that can happen, OBP counts Sacrifice Flies as outs, while they don’t count in batting average. So a player with no walks and who hasn’t been hit by any pitches can have a lower OBP than his batting average if he’s hit a Sac Fly.
