Rays claim right-hander off waivers from White Sox

The Rays announced that they have claimed right-hander Jesse Scholtens off waivers from the White Sox and sent him to Triple-A Durham. Chicago designated him for assignment yesterday. The Rays also announced that catcher Matt Thaiss, who was designated for assignment a few days ago, has cleared waivers and accepted an outright assignment to Triple-A Durham. Scholtens effectively takes the 40-man spot recently vacated by Thaiss.

Scholtens, 31, made his major league debut in 2023 but hasn’t pitched in the big leagues since then. He underwent Tommy John surgery in February of 2024, which led to him missing that entire season. He spent a decent chunk of 2025 on the injured list as well. Once he was ready to come off the IL, the Sox optioned him to the minors.

His major league track record consists of 85 innings tossed in a swing role a couple of years ago. He made 11 starts and 15 relief appearances for the Sox with a 5.29 earned run average, 15.4% strikeout rate, 8% walk rate and 41.3% ground ball rate.

Since those numbers don’t jump off the page, the Rays are presumably more interested in his minor league work. From 2021 to 2023, he tossed 231 2/3 innings at the Triple-A level. Most of that was in the hitter-friendly Pacific Coast League, as Scholtens was in the Padres’ system through the end of 2022. Over those three years, he had a 4.58 ERA but his 24.3% strikeout rate and 7.9% walk rate were both better than average.

He hasn’t yet been able to get back to that level. This year, he has thrown 36 minor league innings with a 5.25 ERA, 19.4% strikeout rate and 7.7% walk rate. But as mentioned, he’s coming back from Tommy John and is perhaps still ramping up. Scholtens still has options and hasn’t yet qualified for arbitration, so he’ll give the Rays some cheap Triple-A pitching depth for now. The club has a decent track record of helping pitchers maximize their results, so perhaps they can sprinkle some of their magic dust on Scholtens in the coming years.

Thaiss, 30, was also acquired by the Rays from the White Sox. Chicago had a bit of a squeeze behind the plate and sent Thaiss to the Rays in May for minor league outfielder Dru Baker. Thaiss got into 25 games for the Rays, backing up Danny Jansen, but he slashed just .225/.304/.282 for a wRC+ of 69.

Tampa shook up their catching spot recently. They traded Jansen to the Brewers but also acquired Nick Fortes and Hunter Feduccia, squeezing Thaiss out of the picture. Since he’s out of options, he got pushed off the 40-man.

His offense has occasionally been intriguing since he draws so many walks but he also strikes out a lot and his defense behind the plate isn’t especially well regarded. There has been enough interest for him to bounce around the league in the past year, going from the Angels to the Cubs, White Sox and Rays in small deals, but every club declined to give him a roster spot this week.

Thaiss has a service clock between three and five years. That means he has the right to reject an outright assignment but has to forfeit his remaining salary commitments in order to do so. He is making $1MM this year, with roughly $300K still to be paid out. Understandably, he had accepted this assignment to keep collecting the rest of that money. He’ll give the Rays some non-roster catching depth for now.

If he’s not added back to the 40-man by the end of the season, he’ll have the right to elect free agency, as is the case for all players with at least three years of service who are removed from a 40-man roster during a season.
