Tony Santillan placed on IL with torn hip labrum, surgery likely per Terry Francona

Tony Santillan is on the 15-day injured list with a torn hip labrum, the Cincinnati Reds announced, and manager Terry Francona told the Reds beat there is a "pretty good chance" the right-hander undergoes surgery as soon as the day after the announcement — per Gordon Wittenmyer of the Cincinnati Enquirer. Santillan is visiting a specialist for an additional opinion, and any recovery timetable will hinge on what that consultation produces.

What happened

The Reds placed Santillan on the 15-day IL after he disclosed, per Wittenmyer, that he began experiencing hip pain in early September and attempted to work through the discomfort before the tear was identified. His final appearance of the season offered a window into what pitching through that pain looked like: his four-seamer sat at 92.8 mph, he walked two of five opponents, and the three balls put in play were hit at an average exit velocity of 96.2 mph. He did not allow a run, which is the kind of thing that earns a pitcher credit even when the underlying numbers are quietly alarming.

The surgery question is not yet settled. Santillan is seeking that additional specialist opinion, and Steve Adams of MLB Trade Rumors notes the timetable for recovery from a potential procedure is not clear until that input arrives. Francona's "pretty good chance" framing, relayed by Wittenmyer, is the closest thing to a directional signal the situation currently offers — and it is a report, not a club announcement.

Why it matters

Santillan's arc this season is the kind of story that makes a front office earn its salary in the offseason. He opened 2026 with 10 2/3 consecutive shutout innings of relief — a brilliant stretch that looked like a continuation of his 2025 form. Then came an oblique strain in May that cost him close to two months. He returned in late August, pitched through what he now says was hip pain from early September, and landed on the IL with a structural diagnosis that carries surgical implications.

The timing matters beyond this season. Per Adams, hip surgery could present the Reds with a roster decision on Santillan heading into the winter. If he is expected to be ready for spring training, the calculus looks different than if the recovery extends into 2027. That question does not yet have an answer.

This news arrives days after the Reds placed Chase Burns on the injured list with a groin strain, ending his 2026 season — a separate blow to a pitching staff that has been navigating health attrition deep into September. The bullpen picture Cincinnati carries into the offseason is now meaningfully different from the one the club envisioned when Santillan was throwing scoreless frames in April.

The numbers

The contrast between Santillan's 2025 and 2026 seasons is stark enough that the numbers do most of the talking without any editorial assistance.

In 2025, Santillan pitched a career-high 73 2/3 innings of relief and posted a 2.44 ERA. He struck out a quarter of the batters he faced, issued walks at a 9.6% clip, and allowed home runs at a rate of 0.86 per nine innings. It was the kind of season that earns a reliever a meaningful role the following year.

In 2026, after that 10 2/3-inning scoreless opening, Santillan has thrown 30 innings across his two injury-interrupted stints. In those 30 frames, he has allowed 29 runs on 37 hits — 11 of them home runs — and 22 walks, while striking out only 24 of 152 opponents, a rate of 15.8%. The home run rate alone represents a dramatic departure from his 2025 form.

The velocity data, per Adams, adds further context. Santillan works with a three-pitch mix — four-seamer, curveball, and slider — and all three pitches have lost at least 1.5 mph in average velocity compared to last year. His four-seamer fell from 96.3 mph in 2025 to 94.5 mph across this season as a whole. That seasonal average still includes his healthier early-season stretch; by his final outing, the pitch was sitting at 92.8 mph — a fastball doing considerably less work than the one hitters faced a year ago.

Where the club stands

The Reds are 73-84 (.465), sitting fifth in the NL Central, 25 games back in the division, and have been eliminated from both the division race and the Wild Card race. Their Wild Card ranking sits ninth, 14.0 games relative to the cut line. They are playing out the schedule on a one-game winning streak.

Upcoming games take Cincinnati to Truist Park to face the Atlanta Braves on Wednesday and Thursday — Andrew Abbott is the probable starter Wednesday against Chris Sale, with Brady Singer lined up Thursday against Tyler Mahle — before the club travels to Rogers Centre to face the Toronto Blue Jays on Friday, with Nick Lodolo the probable starter opposite a pitcher to be determined.

With the postseason no longer in the picture, the remaining games function more as auditions and evaluations than as consequential contests. That context makes the Santillan situation primarily an offseason question rather than a September one.

What we don't know yet

The central unknown is the recovery timetable, and that answer is waiting on the specialist consultation Santillan is currently pursuing. Whether surgery happens, when it happens, and how long the rehabilitation requires are all open questions as of the reporting. Francona's "pretty good chance" language, per Wittenmyer, suggests the direction of travel — but the destination and the arrival date remain unresolved.

Adams notes that the Reds face a roster decision on Santillan depending on what the recovery picture looks like. The specifics of that decision are not yet reportable because the medical picture is not yet complete.

What to watch

The specialist opinion is the first domino. Once Santillan and the Reds have that additional input, the surgical decision and any recovery timetable become clearer — and with them, the shape of the roster question Adams flags for the offseason. Whether Santillan's hip, once addressed, can restore the velocity and command that made him a 2.44-ERA reliever in 2025 is the longer-horizon question, and one that won't have an answer for some time. For now, the desk watches for any club announcement following that consultation.
