Kansas City Royals All-Star catcher Salvador Perez damaged the ulnar collateral ligament in his right elbow, raising the possibility the 2015 World Series MVP may need Tommy John surgery and miss the season. Perez was hurt during a workout Wednesday, and the team said a MRI on Thursday revealed the damage. Perez will travel next week to California for a second opinion from Los Angeles Dodgers head team physician Dr. Neal ElAttrache.
