Bronson Arroyo went on the Disabled List on June 16th after a start against the Dodgers where his velocity was down and he was pulled after five innings. It was his first disabled list in a long and durable career. It turns out he will be there for awhile, as it was reported today that he will require Tommy John surgery and will miss the rest of this season and most likely a decent chunk of next.
Before then, Arroyo had mentioned elbow soreness, but kept pitching. According to reports, Arroyo made his last few starts with a fully torn UCL. Ironically, those were some of his best starts of the season so far with the Diamondbacks. An MRI showed that the UCL had come completely off the bone.
The 37 year old Arroyo had been signed in the offseason on a 2 year/23.5MM deal with a team option for 2016 for 11MM with a 4.5MM buyout. He joins Patrick Corbin, David Hernandez, Daniel Hudson, and Matt Reynolds as current Diamondbacks that have undergone TJ surgery in the past two seasons.
