The Diamondbacks announced Wednesday that they’ve placed righty Jon Duplantier on the 10-day injured list due to shoulder inflammation. Manager Torey Lovullo told reporters prior to tonight’s game that Duplantier will undergo an MRI tomorrow to determine the severity of the injury (Twitter link via Zach Buchanan of The Athletic).
Duplantier, 24, entered the season considered by many to be among the game’s top 100 prospects. He’s given the D-backs 25 respectable innings thus far, pitching to a 4.32 ERA with a 24-to-9 K/BB ratio. It’s an ill-timed trip to the IL for both Duplantier and the organization. He’d been in line for what looked to be an extended audition in the bullpen with both Taijuan Walker and Luke Weaver on the injured list with significant injuries.
Those injuries to Walker and Weaver, plus the struggles of Zack Godley, had prompted the Diamondbacks to turn to Duplantier and fellow rookie Taylor Clarke to help round out the starting five behind Zack Greinke, Robbie Ray and Merrill Kelly. With Duplantier sidelined, the Diamondbacks could again turn to Godley, as there’s not much help looming in Triple-A. Both Taylor Widener and Braden Shipley have ERAs north of 9.00, while other starters such as Anthony Vasquez and Matt Koch have had struggles of their own.
D-backs general manager Mike Hazen chatted with Buchanan for a Q&A (subscription required) that was published earlier today, wherein he stated for the second time in as may weeks that he’s been exploring the market for rotation depth. “Ever since we lost Taijuan Walker and Luke Weaver, we’ve been canvassing, at least watching the market,” said Hazen. One can presume that any type of notable absence for Duplantier will only create more urgency on that front.
