Its possible that his presence caused us to lose games would would have won had a better hitter been in the lineup-because the factors such as the quality of the opposing pitcher or team may have been less competitive when he was in the lineup than when he wasn't. Many other factors could also play a role. Who on the Sox was resting when he played, for example. Unless you correct for the variables its impossible to know the impact of playing him. I do know this: he is a disaster with a bat in his hands and its likely his presence has cost us runs, if not games.
