The Diamondbacks signed reliever Matt Foster to a minor league contract. The move was announced by their Triple-A club in Reno.
Foster, 30, had been pitching for the Algodoneros del Unión Laguna in Mexico for the past month and a half. He thrived in that extremely hitter-friendly setting, allowing only two runs (one earned) through 13 2/3 innings. The righty punched out 13 and didn’t walk any of the 51 batters he faced. It didn’t take long with that kind of production for the Alabama product to find his way back to affiliated ball.
The D-Backs are only the second MLB organization of Foster’s career. He was drafted by the White Sox in 2016 and pitched parts of four seasons for Chicago. Foster’s best season came in 2020, when he turned in a 2.20 ERA while striking out 28% of opponents across 28 2/3 innings. His production tailed off between 2021-22 and he underwent Tommy John surgery early in 2023. Foster missed the entire season and only managed 6 2/3 big league frames late last year. Those came with a 91.9 MPH average fastball velocity that was down two ticks from where he’d been sitting before the surgery.
Arizona’s bullpen has been decimated by injury. Justin Martinez, Cristian Mena, A.J. Puk, Kendall Graveman and Christian Montes De Oca are all on the shelf. Martinez and Montes De Oca have undergone surgeries, and Mena is out for multiple months. Puk was recently shut back down from throwing and is headed for further evaluation due to lingering soreness as he rehabs a flexor strain.
