Yeah, that's what I'm wondering. The only thing at stake is a very slim chance of getting HFA in the AL playoffs, and HFA isn't as big of a deal as it is in the NFL.
I'm sure that Cal will at least get his at bats, both for his personal quest as well as generating fan interest. But beyond there's two schools of thought. One is that you want to keep the pedal to the metal so as not to lose that momentum of having won 17 out of their last 18. After all, they're going to have a week of idleness courtesy of the first round bye. The other side of the coin is that you don't want to burn out your players, risk an injury, etc., in a completely meaningless game.
My guess is that Wilson will play it halfway. He'll let Munoz get some work, but not in all 3 games. Everyone but Woo pitches as scheduled, but all will be on a pitch count and a short rope.
