Alex Carrillo has had a rather arduous road in his professional career, one that eventually resulted in his major league debut in 2025.
Carrillo, now 28 years of age, originally signed as an undrafted free agent with the Texas Rangers out of Faulker University, an NAIA school in Montgomery, Alabama, in 2019. He lost his 2020 season to the COVID-19 pandemic, and was promptly released by the Rangers after appearing in only three games in their organization, all in the Arizona Rookie League.
He got back
on the mound in 2021 in independent ball, signing with the New York Boulders of the Frontier League. He did not perform all that well, earning a 7.11 ERA in 19 innings. He moved onto the Mexican League for the 2022 and 2023 seasons, playing both for the Tigres de Quintana Roo, earning a 8.49 ERA in 29.2 innings, and 8.06 ERA in 22.1 innings, respectively.
2024 saw him move back to the Frontier League, this time with the Washington Wild Things, where he had his best season by a mile. He had a 3.31 ERA, striking out 49 batters in 35.1 innings, which earned him his opportunity with the Mets.
Signed prior to the 2025 season, Carrillo was a mainstay in the Double-A Binghamton and Triple-A Syracuse bullpens before eventually getting a call to the Majors in June. While he was far from incredible for the Mets, giving up seven runs (four homers) in 4.2 innings pitched, even making it from where he started is impressive in and of itself.
Carrillo is bullpen depth, which is something you can never have too much of. While the performances were never really there for Carrillo, save for his 2024 showing for the Wild Things and solid showings in both Double and Triple-A (his Triple-A ERA was actually above average, earning an ERA- of 84, because the offensive environment is absurd there), he continues to get chances due to a hard fastball and an ability to generate whiffs. He can touch triple digits, which will get whiffs at any level, and his 35% and above strikeout rate at both stops last season is a testament to that.
While, at the end of the day, it is not a likely scenario that sees Carrillo end up as a high-leverage reliever, stranger things have happened on the pitching side of the game — Reed Garrett is a good example of how a cutting edge pitching apparatus can take a guy from having 6.00 ERA’s in the Major Leagues to being an important reliever with a few changes. It is hard to predict pitchers, and who will break out, and what organizations have cooking behind the scenes with these arms (and if whatever they have cooking can stick), but a pitcher who throws hard and generate whiffs is going to get some chances, and at the very least be a valuable reliever in Triple-A while providing short-term cover for the big league team.
