Cardinals ace Adam Wainwright is likely out for the rest of the season after injuring his Achilles Friday. He will receive confirmation tomorrow, when he visits a doctor. This will be the second time in the last five years that Wainwright has had a serious injury. He missed the 2011 season due to Tommy John surgery.
This is, of course, unfortunate for Wainwright and the Cardinals, and I hate to see anyone's season derailed by a serious injury. I want the Pirates to beat the Cardinals at full strength, and not as the result of an injury to one of their best players.
For the rest of the season, though, this is a significant problem for the Cardinals, and it should provide a boost to the Pirates. Projection systems suggested Wainwright would be worth about three to four wins the rest of the season. The Cardinals have enough depth that they'll likely have little trouble finding an adequate replacement for Wainwright, but they'll still be short about two to three wins, and that doesn't take into account the fact that some of Wainwright's remaining starts likely would have been against the Pirates themselves. The Cardinals suddenly look like a lesser team than they were last week.
