The Diamondbacks announced today that left-hander has been placed on the 15-day injured list, retroactive to May 15th Joel Kuhnel Jersey , with left shoulder inflammation. Lefty has also been optioned to Triple-A Reno. To take those two spots, the club has recalled right-hander and selected the contract of righty . The 40-man roster had two vacancies due to and being designated for a signment earlier this week. Per John Gambadoro of Arizona Sports 98.7 FM Phoenix, righty will take E-Rods rotation spot, taking the ball on Tuesday. There havent been a lot of publicly reported details about Rodrguez or his injury, but its po sible he was feeling it last time out. He started on Wednesday against the Giants but wasnt very effective. He allowed four earned runs in four innings and was pulled after throwing just 76 pitches. The velocity on most of his offerings was down about one mile per hour relative to his previous start. Perhaps the club will provide more information but it seems the lefty will need to mi s at least a couple of starts. That will give Nelson a chance to retake a rotation spot, at least for now. He logged 150 2/3 innings for the Snakes last year, mostly as a starter. He had a 4.24 earned run average, 20% strikeout rate and 5.4% walk rate. Despite those strong numbers, he got pushed down the depth chart when the Snakes signed in the offseason. Burnes joined a rotation group next to , , , and Rodrguez. Montgomery required Tommy John surgery in March, but Nelson was still unable to get a rotation job. He opened the year in a long relief role and has thrown 26 1/3 innings with a 5.13 ERA, but better peripherals. He has struck out 25% of batters faced while giving out walks at an 8.9% clip. A low 62.5% strand rate is not doing him favors, perhaps why his FIP is 3.71 and his SIERA at 3.45. Kelly, Gallen and Montgomery are all free agents at the end of this year, while Burnes has an opt-out after 2026. Nelson is under club control through 2028 and could perhaps earn a long-term rotation spot with some strong results this year. Though if Rodrguez returns in relatively short order, its po sible Nelson finds himself back in the bullpen again. Montes De Oca, 25, gets the call to the big leagues for the first time. An international amateur signing out of the Dominican Republic, he has 181 1/3 minor league innings under his belt to this point in his career. In that time, he has a 4.17 ERA, 25.2% strikeout rate and 8.2% walk rate. Hes out to a good start this year, despite pitching in the hitter-friendly Pacific Coast League. In 19 Triple-A innings, he has a 2.37 ERA, 23.3% strikeout rate, 5.5% walk rate and 57.7% ground ball rate. Photo courtesy of D. Ro s Cameron, Imagn Images Dylan Carlson Jersey
