Jays have a high performance team and the days off are planned to create max performance probability, and presumably durability.
Not PHing Springer for Zimmer in the 6th with 2 on doesn't make sense to me. Springer can get hurt in so many ways, and with a day off tomorrow, was him playing OF 2-3 innings and having 2 PAs that much of a consideration?
These games now matter as much as later in the year, and not much point in a healthy Springer if we don't produce enough W's. A hit from George could have buried the A's at that point, and the probability delta of him doing damage over Zimmer is dramatic.
