Every successful team needs a steady hand in the bullpen, and for the Cincinnati Reds this season, that hand belongs to Tony Santillan. While the spotlight naturally shines on young stars like shortstop Elly De La Cruz, first baseman Sal Stewart, and ace pitcher Chase Burns, Santillan has quietly become an indispensable piece of the Reds' pitching puzzle.

The 29-year-old reliever has been a model of consistency, delivering 13 scoreless appearances in his first 16 outings. After a rocky start to the week—blowing his second save of the season in Tuesday's 3-2 loss to the Chicago Cubs—it's worth noting that 13 of his first 14 games were spotless. That streak only ended in Sunday's 1-0 loss to the Pittsburgh Pirates, followed by Tuesday's hiccup. For context, that's the kind of reliability every manager dreams of from their bullpen.

Santillan's production is no flash in the pan. Last season, he posted a stellar 2.44 ERA over 80 games, and his career numbers—a 3.01 ERA across 175 games (five starts)—speak to his enduring value. This year, his role has become even more critical with closer Emilio Pagán struggling mightily. Pagán has six saves in nine opportunities but carries a bloated 6.43 ERA over 15 appearances. Worse still, he landed on the 15-day IL with a hamstring strain suffered in Tuesday's ninth inning, and MLB.com reports he's not expected back until June or July.

Stepping into that void, Santillan has been a rock. He leads the Reds with nine holds, while right-hander Graham Ashcraft (1.93 ERA) is second with seven. Ashcraft's own recent stumble—giving up a two-run homer to Cubs star Pete Crow-Armstrong in the ninth inning on Wednesday—only underscores how vital Santillan's steadiness has been. That blown save tied the game 6-6, and reliever Brock Burke eventually walked in the winning run in the 10th.

For Santillan, this season is proving that last year's breakout was no fluke. Drafted in the second round by the Reds in 2015, the 6-foot-3, 285-pound right-hander made his MLB debut in 2021, posting a 2.91 ERA over 26 outings (four starts). A 5.49 ERA in 2022 and a injury-plagued 2023 (just three games due to back and knee issues) might have raised doubts, but he's silenced them with authority. Now, with 16 outings already under his belt—more than he had in any full season before last—Santillan is proving he's a long-term piece the Reds can count on.
