Overbay is definitely not a 'black hole' type of player because he is selective on pitches and seems to be determined not to spoil runners on base situation. Especially, when the elite type of pitcher is on the mound, he usually hit the ball to the center field(usually singles), or take pitchers carefully, or move the runners because he knows Carlos Lee is behind him. But overall, he simply has not hit the ball hard to make easy double, HR this season.
