The Arizona Diamondbacks have made a surprise roster move, less than an hour prior to first pitch against the Athletics on Tuesday night. Arizona has placed right-handed flamethrowing reliever Drey Jameson on the 15-day injured list with what is being called right hip inflammation. To take Jameson's place on the major league roster, right-hander Gerardo Carrillo has been recalled from Triple-A Reno. Carrillo had been added to the 40-man roster this weekend as a part of the move that landed outfielder Lourdes Gurriel Jr. on the 10-day IL.

He's missed significant time to injury on several occasions, including Tommy John surgery that claimed all of his 2024 season and battled another elbow issue later in the 2025 season. Finally fully healthy coming into 2026, Jameson looked to have made significant improvements. Despite his 8.44 ERA in spring training and subsequent option, Jameson earned his recall to the major leagues back on June 6. He's performed relatively well in a long relief, low-leverage role with Arizona's big league club. posting a 4.67 ERA in 17.1 innings with a 4.38 ERA and 4.08 FIP. Jameson last pitched in Sunday's wild walk-off comeback win over the St. Louis Cardinals, throwing 42 pitches in 2.0-plus innings of work. Though not exactly a weapon out of Arizona's top-end bullpen group, his services have still been valuable to the Diamondbacks.It is unclear as of this writing exactly what occurred for Jameson to suffer this injury, and there has been no reported timeline for his return. Since the move is retroactive to July 20, the earliest he could return would be August 4.Add us as a preferred source on GoogleFollow
