Felipe Paulino has been diagnosed with a torn ulnar collateral ligament in his right elbow and will likely need Tommy John surgery. Well, that came out of nowhere. Paulino made a rehab start with Double-A Northwest Arkansas Wednesday and had been slated to rejoin the Royals rotation next week, but evidently he hurt himself during the outing. It's a big blow to a Royals rotation that's already lost Danny Duffy to Tommy John surgery.
