This probably also means Wainwright will return to the rotation instead of his rumored move to the pen. This may drive the Cards to ease back on the season throttle to make sure they have a healthy rotation in the future. This may be the straw that breaks the Cardinals back, but I would love to see them hang tough and battle Milwaukee down the stretch. I also hope that Carpenter really only has a minor thing here, I think he has worked very hard to get back and respect everything he does as a competitor.
