Viera was cut loose earlier this month after undergoing Tommy John surgery during spring training. The hard-throwing 32-year-old righty will likely be sidelined until the midway point of the 2026 season given the timing of the procedure. He’s made 53 relief relief appearances in the big leagues dating back to 2017.

The operation will cost Vieira all of 2025, and potentially a portion of 2026 as well. The hard-throwing right-hander is just organizational depth at this stage of his career.

The 31-year-old hurler had been designated for assignment last weekend as the Diamondbacks needed to free up a spot on their 40-man roster. He passed through waivers unclaimed though and it sounds like he’ll accept the assignment at report to Triple-A Reno where he’ll continue to serve as auxiliary bullpen depth.

Viera has been removed from Arizona’s 40-man roster to make room for newly-acquired left-hander A.J. Puk on the Diamondbacks’ active roster. The hard-throwing 31-year-old righty recorded a solid 2.87 ERA, 1.28 WHIP and 14/9 K/BB ratio across 15 2/3 innings (11 appearances) for Arizona after being claimed off waivers back in early June from the Orioles.
