Santana struck out one over two-thirds of a scoreless inning to earn the save in Monday's 5-4 extra-inning win over the Royals.
Santana inherited a precarious situation, entering after the Royals had already scored four runs in the bottom of the 10th inning to whittle Arizona's five-run lead to one. However, the right-hander retired Michael Massey on a flyout before striking out Nick Loftin to end the game. It was Santana's first appearance in eight days, and it extended his streak of scoreless outings to four. Since being called up to the Diamondbacks' big-league roster Aug. 16, Santana owns a 1.50 ERA and a 6:1 K:BB across six innings in seven relief outings.

Arizona selected Santana's contract from Triple-A Reno on Sunday.
Just 10 days after signing a minor-league deal with Arizona, Santana will be moved up to the 40-man roster and 26-man active roster. Before joining the Diamondbacks, Santana had spent the season in Pittsburgh's big-league bullpen, posting a 6.05 ERA, 1.51 WHIP and 37:21 K:BB over 41.2 innings. Arizona designated Philip Abner for assignment in order to clear room on the roster for Santana.

The Diamondbacks signed Santana to a minor-league contract Wednesday.
Santana was cut loose by the Pirates last week after collecting a 6.05 ERA and 37:21 K:BB over 41.2 innings. Whether the right-hander is able to rediscover his form from 2025 -- when he posted a 2.18 ERA and 0.87 WHIP with 16 saves -- is very much in question, but bringing him aboard on a minor-league pact is a no-risk move for Arizona that might have moderate upside.

The Pirates released Santana on Wednesday, Mark Feinsand of MLB.com reports.
Santana passed through waivers unclaimed after being scrubbed from the Pirates' 40-man roster. The Pirates are responsible for what remains of Santana's $3.5 million salary, and the reliever should latch on with a new organization quickly now that he can be signed to a prorated veteran minimum contract. Santana holds a 6.05 ERA and 37:21 K:BB over 41.2 innings in the majors this season.

The Pirates designated Santana for assignment Thursday, Colin Beazley of the Pittsburgh Post-Gazette reports.
The move frees a spot on the 26-man and 40-man rosters for the addition of Ron Marinaccio. Santana began 2026 high in the Pirates' bullpen hierarchy and was in the closer mix, but he has struggled with consistency all season and had allowed 10 runs in 7.1 innings this month. It's possible he'll draw interest via waivers, though his $3.5 million salary could be a deterrent for some clubs.

Santana (2-3) allowed three runs (two earned) on four hits without recording an out to take the loss Friday against the Phillies.
Santana worked the 10th inning, following Gregory Soto, who blew a three-run lead one frame prior. Santana allowed a leadoff double and three consecutive singles before being pulled, and he's now allowed multiple earned runs in three of his last seven appearances. He also hasn't logged a save since April 15 and isn't likely to see many chances in the near future given his current form.
