2025 Fantasy Outlook
Santillan was limited to just three appearances in 2023 due to injuries, but re-signed with the Reds last offseason on a minor-league contract. Despite an outstanding spring, he failed to make Cincinnati's Opening Day roster and was re-assigned to the minors. The 27-year-old was recalled in July and spent the remainder of the 2024 campaign with the Reds, pitching to a 3.00 ERA, 1.00 WHIP and 46:9 K:BB across 30 frames. Santillan's 37.7 percent strikeout rate and 30.3 K-BB percentage were top-5 marks among relievers who pitched a minimum of 30 innings, putting him back on the deep-league radar for 2025. He's pitched in a versatile role in the past, capable of working as an opener, closer or multiple innings at a time. Santillan certainly has the talent to overtake Alexis Diaz as the Reds' closer, and the opportunity may be there with Terry Francona now managing the team, but health is likely to be his biggest obstacle in doing so.

Mentioned as possible closer option
Reds manager Terry Francona said Wednesday that while Santillan is an "easy choice" to be the closer, "he might be too valuable getting to the ninth," Charlie Goldsmith of the Dayton Daily News reports.
ANALYSIS
While Francona admitted he's not sure who his closer will be while Alexis Diaz (hamstring) is sidelined, it's notable that he mentioned Santillan in the fashion that he did, suggesting the right-hander might be the favorite to see the first opportunity. Santillan began last season in the minors after re-signing with the Reds last offseason on a minor-league deal, but he was excellent with the big club after being called up, posting a 3.00 ERA and 46:9 K:BB over 30 innings. Taylor Rogers, Scott Barlow, Graham Ashcraft and Emilio Pagan are other candidates to see save chances with the Reds.

Santillan surprisingly earned the first save of the 2022 MLB season. The Reds didn't deploy him as a traditional closer, but was one of their highest leverage relievers early in the season. He finished with four saves and six holds across 21 appearances before a lower back strain ended his campaign in mid-June. Santillan threw both his slider and 96.2 mph fastball equally, but the latter was hammered to a .350 BA and .475 SLG despite adding 1.2 mph on the pitch, on average. The right-hander previously threw a changeup to left-handed hitters in 2021, but didn't have success with it and removed it from his arsenal last year. Despite a fairly secure high leverage role when healthy, Santillan is too risky of a spec for 2023 drafts. He's a WHIP liability with a career 4.7 BB/9 and is coming off a lengthy injury.

Latest Fantasy Rumors

Unlikely to return
Santillan, out with a back injury, is a "long shot" to return this season, reports Bobby Nightengale of The Cincinnati Enquirer.
ANALYSIS
After an excellent rookie campaign in 2021, hopes were high for Santillan this season but poor play and a back injury put a damper on his sophomore season. The 25-year-old was the Opening Day closer for the Reds, pitching a perfect ninth inning to save the game against the defending champs from Atlanta. There weren't many more save chances in the early going and when there were, he blew three opportunities. All in all, he posted a 5.49 ERA, 1.78 WHIP and 21:12 K:BB in 19.2 innings for Cincinnati. He's quite likely to be a part of the Reds' plans moving forward but may have to serve as a setup man to the new closer, Alexis Diaz, heading into 2023.
