The Reds announced this morning that they’ve selected the contract of right-hander Tony Santillan. To make room or Santillan on the 40-man and active rosters, outfielder Nick Martini was transferred to the 60-day injured list while right-hander Carson Spiers was placed on the 15-day IL with a right shoulder impingement.
It’s far from Santillan’s first stint in the majors with Cincinnati. The 27-year-old was a second-round pick by the club back in 2015 and made his debut with the club back in 2021, when he was one of the club’s top relievers. In 43 1/3 innings of work that season, Santillan posted a strong 2.91 ERA (162 ERA+) despite a somewhat lackluster 4.62 FIP in 26 games. While Santillan struck out an excellent 29.5% of opponents, his 11.1% walk rate and his seven homers allowed both weighed that down somewhat.
Those issues, combined with a back strain that sidelined Santillan for much of the 2022 campaign and the early part of the 2023 season, left the right-hander on the outside looking in of the club’s bullpen mix going forward, however. Over those two injury-marred seasons, Santillan struggled to a 5.09 ERA with a 4.52 FIP, 19.3% strikeout rate, and 14.9% walk rate while pitching just 23 total frames in the majors. His work in the minors last year wasn’t much better, as he was torched to the tune of a 7.88 ERA in 35 appearances at the Triple-A level last season.
Despite that rough performance, the Reds nonetheless re-signed Santillan to a minor league deal this past offseason, and that decision has largely paid off. The righty has looked much better at Triple-A this season than he did a year ago, posting a 3.49 ERA with a 3.87 FIP in 38 2/3 innings of work as a single-inning reliever. While his 13.2% walk rate is still elevated as ever, his strikeout rate has bounced back in a big way to compensate: he’s fanned 30.5% of opponents this year. That high strikeout rate was a big part of what made him so successful in 2021, and given that it’s hardly a surprise that the Reds would be interested in seeing what he can do at the big league level.
Making room for Santillan on the Cincinnati roster is Spiers, who has emerged as a quality middle relief arm for the Reds this year after struggling in his first taste of big league action last season. The 26-year-old posted an ERA north of 6.00 in 13 innings of work in 2023 but has emerged looking far better this season with a solid 3.83 ERA and even more impressive numbers under the hood while swinging between the rotation and bullpen this year. While Spiers has only struck out 20.5% of batters faced this year, an excellent 4.5% walk rate has left him with a 3.51 FIP and a 3.86 SIERA, both of which are well above average marks. Fortunately, Spiers told reporters (including Charlie Goldsmith of the Cincinnati Enquirer) this afternoon that his injury figures to be only a short-term issue and that he expects to miss just one start.
As for Martini, the outfielder’s transfer to the 60-day IL is hardly a surprise given the fact that he underwent surgery on his thumb earlier this week. Martini’s timetable for return isn’t entirely clear, though he’s expected to be able to return before the end of the year. That return now won’t come until after September 5, 60 days after he was first sidelined by the injury. In 163 trips to the plate with the Reds this year, Martini has slashed a lackluster .212/.272/.370.
