Picks up first save
Jameson earned a save in a scoreless inning during Sunday's extra-innings win over the Cubs.
Analysis
Jameson was promoted from Triple-A Reno on Saturday and secured a save in his season debut with the Diamondbacks. It was his first MLB appearance since July 6, 2023 after missing the entire 2024 campaign while recovering from Tommy John surgery. Jameson likely won't see many save opportunities out of Arizona's bullpen.

Up from Triple-A
The Diamondbacks recalled Jameson from Triple-A Reno on Saturday.
Analysis
Jameson will be joined by J.P. Feyereisen and Juan Morillo in moving to Arizona to replace Joe Mantiply, Bryce Jarvis and the injured A.J. Puk (elbow). Jameson has been effective in seven outings with Reno, giving up two runs on 6.2 innings while punching out 10 batters and walking none.
