Arizona RHP Arroyo to have Tommy John surgeryPosted: Updated:
Arizona right-hander Bronson Arroyo will undergo Tommy John surgery, becoming the third Diamondbacks pitcher to undergo the ligament-replacement procedure this season.
Arroyo had never been on the disabled list during his 15-year career before going out on June 16 with elbow tendinitis. Arroyo said on Monday that an MRI revealed that the ulnar collateral ligament had torn completely off the bone and he will have surgery in the next week or so.
The 37-year-old said he believes he tore the ligament during a complete game against Washington in May, noticing a steady drop-off in velocity after that game. Arroyo was 7-4 with a 4.08 ERA in 14 starts this season.
He joins Patrick Corbin and reliever David Hernandez on Arizona's list of pitchers to have Tommy John surgery. Left-hander Daniel Hudson has had the surgery twice, in 2012 and 2013.
