Daniel Hudson will likely need Tommy John surgery, Joe Saunders remains on the disabled list with a shoulder injury, and Trevor Bauer has completed all of four innings at the MLB level, but the Diamondbacks say they aren’t currently looking for pitching reinforcements.
"I think we feel like we've got enough depth," general manager Kevin Towers told Nick Piecoro of the Arizona Republic. "We actually considered even moving some of our depth. It's probably a good thing we didn't, for this very reason."
The Diamondbacks expect Saunders to return from the disabled list around the All-Star break and Towers noted that the left-hander is “feeling great.” Saunders drew trade interest from the Orioles and other clubs earlier in the season.
Bauer, Ian Kennedy, Trevor Cahill, Wade Miley and Josh Collmenter currently round out Arizona’s rotation. The group ranks fourth in MLB in walk rate (2.5 BB/9), ninth in FanGraphs’ wins above replacement (7.5), 16th in strikeout rate (6.9 K/9), and 19th in ERA (4.21). Pitching prospects Tyler Skaggs and Patrick Corbin provide the Diamondbacks with some minor league alternatives.
