I'm looking at the Cubs box score, and have noticed that Troy O'Leary is batting third, taking the spot of the injured Sammy Sosa. Troy doesn't really strike me as a #3 hitter. Yet managers seem to do this all the time. Someone's out of the lineup, so instead of rearranging the order to optimize the offense, they just stick the substitute in the vacated spot. O'Leary does have 2 HR and 7 RBI since Sosa's toe surgery, but he's only batting .267 with 0 BB and a .258 OBA!
