The Arizona Diamondbacks have added pitcher Anthony DeSclafani to their major-league roster after he opted out of his minor-league contract with the New York Yankees. At 35, DeSclafani will provide veteran experience primarily from the bullpen, having previously posted a 4.50 ERA in Triple-A. His arrival coincides with Bryce Jarvis being sent down, and the team has placed Justin Martínez on the 60-day injured list due to elbow surgery. The Diamondbacks are also missing key arms, including Corbin Burnes, who is recovering from Tommy John surgery, and A.J. Puk, who has been sidelined since mid-April with elbow issues. DeSclafani holds a career record of 54-56 and a 4.20 ERA, with his last major league outing in July 2023.
