Diamondbacks trade rumors: Bronson Arroyo needs Tommy John surgery

Cross Bronson Arroyo's name off the Diamondbacks' for-sale list. The veteran right-hander told reporters today that he will have season-ending Tommy John surgery to repair a torn ulnar collateral ligament in his right elbow, meaning that he won't be traded in advance of the trade deadline.

Arroyo, who signed a two-year, $23.5M deal with Arizona in February, finished his season with a 7-4 record and 4.08 ERA in 14 starts. This will be the first time since 2004 that he won't reach the 175-inning mark for a season.

The Diamondbacks, who are being viewed as one of the most aggressive sellers in baseball after moving Joe Thatcher, Tony Campana and Brandon McCarthy over the weekend, were reportedly exploring the idea of moving Arroyo for younger pieces this summer. Obviously, that won't be the case now, and Arroyo will return next season and reclaim his place in the D-Backs rotation.

Before the season, Arizona's rotation was expected to be Patrick Corbin, Wade Miley, Arroyo, McCarthy and Trevor Cahill. Corbin and Arroyo went down with Tommy John surgery, McCarthy struggled and was eventually traded, and Cahill is currently in the minors as he works his way back after struggling this season. With so many question marks in the rotation at the moment, the team is turning to Miley, Josh Collmenter, Chase Anderson, Vidal Nuno and Mike Bolsinger to eat innings as they try to escape the NL West cellar.
