Worthy: Cardinals roster expands, but no JJ Wetherholt or Quinn Mathews. It's no surprise. Young catcher Jimmy Crooks is getting a taste of the big leagues, but JJ Wetherholt and Quinn Mathews remain in Memphis. What gives?

Turning things around at Triple-A Mathews has a 2.70 ERA, 1.08 WHIP and 25:5 K:BB in 16.2 innings over his last three starts for Triple-A Memphis.

Impact Mathews has failed to meet expectations this season, logging an 18 percent walk rate and 1.65 WHIP in 65 innings at Triple-A with an early-season shoulder injury mixed in. However, this most recent stretch is his best stretch of the season, so it would at least seem that he is healthy and making progress with his shoddy control.

Activated from Triple-A IL Mathews (shoulder) was activated from Triple-A Memphis' 7-day injured list Saturday.

Impact After missing more than a month of action with left shoulder inflammation, Mathews tossed five scoreless innings with an 8:0 K:BB in two rehab outings before being activated. His first outing back in the Memphis rotation didn't go as well, as he yielded two runs with a 3:3 K:BB over 2.2 frames Saturday. The southpaw has permitted nine runs with a 10:18 K:BB in 13 innings covering four starts with Memphis this season, so he'll be looking to get back on track in June now that he has hopefully put his shoulder issue behind him.

Starting rehab assignment Mathews (shoulder) has been sent to the rookie-level Florida Complex League Cardinals to begin a rehab assignment.

Impact It had been reported that Mathews would make a start for the FCL Cardinals last week, but it appears his first appearance for them will come this week. The left-hander has been shelved since mid-April with mild left shoulder soreness but is now ready to pitch in games. Mathews will eventually move back up to Triple-A Memphis once the Cardinals feel he's ready.

Ready to return Mathews (shoulder) will make a rehab start this week with the Cardinals' Florida Complex League affiliate, Derrick Goold of the St. Louis Post-Dispatch reports.

Impact Mathews resumed a throwing program in late April as he bounces back from mild left shoulder soreness, and he's now ready to pitch in games. The left-hander will eventually move back up to Triple-A Memphis, where he posted a 6.10 ERA and 7:15 K:BB over his first 10.1 innings before getting injured.

Set to resume throwing Mathews (shoulder) will resume a throwing program Wednesday or Thursday, John Denton of MLB.com reports.

Impact The top prospect was placed on the 7-day injured list at Triple-A Memphis last week with mild left shoulder soreness, an issue Mathews believe arose because his mechanics got out of whack. He's been doing resistance-band and weighted plyometric ball work and the resumption of a throwing program is imminent. It's not clear when Mathews might be ready to rejoin Memphis' rotation. He's struggled in the early going this season, holding a 6.10 ERA and 7:15 K:BB over his first 10.1 innings.

On Triple-A IL with sore shoulder Cardinals president of baseball operations John Mozeliak said Monday that Mathews was placed on the 7-day injured list at Triple-A Memphis due to left shoulder soreness, Daniel Gue...

Impact When asked about a timetable for Mathews' return, Mozeliak simply replied, "TBD." Mathews' velocity was down in his last outing with Memphis and he's posted a 6.10 ERA and 7:15 K:BB over his first 10.1 innings this season, so it's possible the shoulder has been nagging at him for a while. The Cardinals will proceed cautiously with the top prospect.

Misses out on Opening Day rotation The Cardinals reassigned Mathews to minor-league camp Sunday.

Impact Though Mathews is regarded as one of St. Louis' top pitching prospect, he was always facing an uphill battle to win a spot in the Opening Day rotation after having made just four starts above the Double-A level. The 24-year-old southpaw should still make his MLB debut at some point in 2025, but for now, the Cardinals will send him to minor-league camp to open up more innings in Grapefruit League play for other rotation candidates. He'll continue to stay in a starter's schedule at minor-league camp, with Rob Rains of StLSportsPage.com noting that Mathews will cover three innings Sunday in a game on the back fields.

Dazzles in spring debut Mathews fanned three batters while allowing two hits and one walk over two scoreless innings in Tuesday's Grapefruit League game against the Blue Jays.

Impact The reigning minor league strikeout leader set down Vladimir Guerrero swinging in a perfect first inning before adding a pair of strikeouts in the second to escape a bases-loaded jam. Mathews has an outside shot to win a spot in the Cardinals' rotation if he wows this spring, but he's most likely pegged for Triple-A Memphis. Even if he doesn't break camp with the big club, he's a good bet to spend a good chunk of 2025 in the St. Louis rotation.
