Tigers claim Carlos Hernández

The Tigers have claimed right-hander Carlos Hernández off waivers from the Phillies, according to announcements from both clubs. Philadelphia had designated him for assignment last week. Detroit had an open 40-man roster spot due to designating righty John Brebbia for assignment yesterday. Hernández is out of options, so the Tigers will need to open an active roster spot once he reports to the club.

Hernández, 28, has big velocity but hasn’t always been able to translate it into results. After working in a swing role with the Royals from 2020 to 2022, he seemed to be breaking out as a reliever in the first half of 2023. Through August 1st of that year, he had thrown 54 innings with a 3.67 earned run average, 30.2% strikeout rate and 7.4% walk rate.

Unfortunately, he posted a 10.69 ERA in his final 16 innings that year. In 2024, he battled some shoulder soreness and spent the first two months of the season on the injured list. When he was reinstated, the Royals shuttled him to Triple-A and back. He posted a 3.30 ERA in the big leagues that year but with subpar strikeout and walk rates of 20.9% and 12.4% respectively. He also had a 5.40 ERA in his minor league work.

He came into 2025 out of options and didn’t make the Kansas City roster out of camp, which led him to the waiver wire and a claim by the Phillies. He logged 25 2/3 innings for the Phils this year with a 5.26 ERA, 18.7% strikeout rate and 10.6% walk rate. Though he hasn’t been able to execute, the stuff is enticing, with Hernández averaging just under 98 miles per hour on his fastball this year while also throwing a splitter, slider and knuckle curve.

Perhaps the Tigers feel they have a path to help him better harness that stuff. Or perhaps he’s just available when they want a fresh arm. Righty Will Vest departed yesterday’s game due to some discomfort in the pinky finger of his throwing hand, per Cody Stavenhagen of The Athletic. Perhaps he will require a stint on the injured list, opening a hole in the big league bullpen. Since the Tigers had an open 40-man spot anyway, claiming Hernández is perhaps a bit of insurance for Vest.

It’s also possible that the Tigers plan to put Hernández back on waivers shortly with the hope of passing him through unclaimed. The Tigers have the best record in baseball and therefore the final waiver priority, meaning the other clubs just passed on him. Hernández has between three and five years of big league service time, meaning he has the right to reject an outright assignment but would have to forfeit the remainder of his $1.16MM salary in order to do so. For now, he’ll report to the Tigers and try to put some good outings together for them.
