Rule Clarification:
I hadn't considered this possibility, but if the player's all-star season that you want to use occured during a year where he played for 2 or more teams (i.e., Esteban Loaiza, 2004 White Sox & Yankees), you must select the team that he made the all-star team for (in this case the White Sox). So you would have to select either the 141-IP partial White Sox season or the 183-IP combined White Sox season. You cannot select the 43-IP partial Yankees season, since that goes against the spirit of the All-Star rule.
