They're making decisions on who to re-sign for next year. We all know what Clippard can do for us, but I guess they wanted another look at Slaten. Certainly it made sense to use a lefty in that situation.
The decision not to sign Slaten should have already been made. What about Burnett, Mattheus, etc? They are on the true hot seat for next year. Slaten has been the worst pitcher in baseball this year.
Davey blew it. He obviously didn't care about winning these last two games.
