Jason Hammel underwent successful surgery on his right knee on Monday.
Hammel has been pitching through loose cartilage in the knee for most of the season, but he was finally forced to go under the knife. He’ll need 3-4 weeks of recovery time, but it’s possible he could be sidelined until September. Barring a trade, the Orioles are going to have a tough time hanging in the Wild Card race without him.
