Preparing to return to the major leagues after a one-season absence, Salvador Perez caught a bullpen session from prospect Brady Singer in the Kansas City Royals' first spring training workout on Wednesday. Perez hurt his a ligament in his right elbow during drills in spring training last year, and Los Angeles Dodgers team physician Dr. Neal ElAttrache performed Tommy John surgery on the six-time All-Star on March 6. Perez is hitting and throwing to bases.
