The Mariners designated Hahn for assignment Friday, Shannon Drayer of SeattleSports.com reports.

Hahn has given up four runs (three earned) with a 3:5 K:BB over five innings this season with the Mariners. He wound up re-signing with Seattle after being removed from its 40-man roster in April, but it's not clear what his intentions are this time around.

Thompson is back in St. Louis to be re-evaluated after suffering a setback with his injured left lat, John Denton of MLB.com reports.

Thompson was diagnosed with a left lat strain in early March and shut down for about a month. It's not clear where he was at in his throwing program when he experienced a setback, but more information about his status should be available after he's looked at by doctors in St. Louis.

The Athletics recalled Lopez from Triple-A Las Vegas on Friday, Martin Gallegos of MLB.com reports.

Lopez is expected to start Friday against the Phillies, as J.T. Ginn (quadriceps) recently landed on the 15-day injured list. Lopez made a spot start against the Rangers back on April 29, allowing three earned runs on six hits and four walks across 2.2 innings of work. He struck out four and took the loss. Lopez could make multiple starts for the Athletics while Ginn is sidelined.

The Tigers optioned Guenther to Triple-A Toledo on Friday, Evan Petzold of the Detroit Free Press reports.

Guenther has yielded seven runs (six earned) with an 8:5 K:BB over 10.1 innings with the big club this season. He's clearing out to make room on the roster for the return of Matt Vierling (shoulder).

Montas (lat) said Friday he's beginning a rehab assignment at High-A Brooklyn and will make a start Saturday, Jon Heyman of the New York Post reports.

Montas suffered a high-grade right lat strain in February and faced hitters for the first time May 16. He's now been cleared to begin what's expected to be a somewhat lengthy rehab assignment. Per Andrew Tredinnick of The Bergen Record, Montas will throw 30-to-35 pitches Saturday. The 32-year-old logged a 4.84 ERA across 150.2 regular-season innings in 2024.

The Cardinals recalled Svanson from Triple-A Memphis on Friday, Derrick Goold of the St. Louis Post-Dispatch reports.

Svanson has pitched well during his time with the big club this season, permitting two runs with a 7:3 K:BB across 6.2 frames. He will operate in middle relief out of the St. Louis bullpen.

The Cardinals optioned Roycroft to Triple-A Memphis on Friday, Derrick Goold of the St. Louis Post-Dispatch reports.

Roycroft has had two different stints in the majors this season and neither of them have been successful, as he's yielded a 10 runs (eight earned) with a 6:8 K:BB over 10 innings. His spot on the roster and in the bullpen will be absorbed by Matt Svanson.

The Brewers optioned Rodriguez to Triple-A Nashville on Friday.

Rodriguez will yield his spot on the active roster for Aaron Ashby (oblique), who's being activated from the 15-day injured list. The 23-year-old served as a bulk reliever for the Brewers on Thursday, allowing three runs on five hits and four walks across 3.1 innings.

The Giants announced that Harrison will start Saturday's game against the Nationals, Alex Pavlovic of NBC Sports Bay Area reports.

Harrison will take over the rotation spot that previously belonged to Justin Verlander (pectoral), who was placed on the injured list Thursday. The 23-year-old lefty has made four relief appearances since being recalled earlier this month, allowing two runs with a 7:3 K:BB over 5.1 frames. Harrison had been starting at Triple-A Sacramento prior to his call-up but hasn't pitched more than two innings in over three weeks, so he's likely to have a limited workload versus the Nationals.

The Giants recalled Beck from Triple-A Sacramento on Friday.

He's taking the roster spot vacated by the injured Justin Verlander (pectoral). Beck has been used in a multi-inning relief role this season with Sacramento, posting a 3.24 ERA and 29:11 K:BB over 25 innings. He could offer some length out of the bullpen Saturday behind Kyle Harrison.
