Woods Richardson will no longer start Sunday's game against the Guardians, Bobby Nightengale of The Minnesota Star Tribune reports.

The Twins will give Woods Richardson a few extra days of rest after the 24-year-old opened the second half of the season with a 7.04 ERA and 2.09 WHIP through 7.2 innings over two starts. Jose Urena will take the mound to begin Sunday's contest instead; meanwhile, Minnesota has yet to announce when Woods Richardson will make his next start.

Manager Alex Cora said Saturday that Houck (elbow) will undergo Tommy John surgery, Gabrielle Starr of the Boston Herald reports.

Houck has been on the injured list since May with a right elbow strain, and after suffering a setback during his most recent rehab start July 9, he'll now elect to go under the knife to address the injury. The right-hander will close the book on 2025 with an 8.04 ERA and 1.69 WHIP through 43.2 innings, and because his procedure will happen late in the 2025 season, he likely won't be ready to return to a big-league mound until 2027.

Povich (hip) will be activated from the 15-day injured list to start Monday's game against the Phillies in Philadelphia, Matt Weyrich of The Baltimore Sun reports.

Povich landed on the IL in mid-June with hip inflammation and made one rehab start in late June before being shut down with additional soreness. Since restarting his assignment July 13, the 25-year-old has posted a 3.38 ERA and 0.94 WHIP through 16 innings while striking out 18 batters across four starts between High-A Aberdeen and Triple-A Norfolk. He built up to 86 pitches during his most recent minor-league outing Tuesday, which could allow him to avoid workload restrictions during his first start back in the big leagues.

Lorenzen (oblique) faced five batters in a live batting practice session Thursday, MLB.com reports.

Assuming Lorenzen experienced no complications in his recovery from a left oblique strain coming out of the workout, he's expected to begin a rehab assignment at some point during the upcoming week. Lorenzen has been on the shelf since July 14, and given the relative brevity of his absence, he could be ready to rejoin the Kansas City rotation after just one rehab start.

Bieber (elbow) is expected to throw 70-to-75 pitches in a rehab start for Triple-A Buffalo on Sunday, Keegan Matheson of MLB.com reports.

If everything goes well, Bieber could then return from the 60-day injured list to make his Blue Jays debut the following weekend in a road series against the Dodgers. Acquired from the Guardians at the trade deadline, the 30-year-old right-hander and 2020 American League Cy Young Award winner is in the final stages of his recovery from Tommy John surgery he underwent in April 2024.

May is scheduled to start Wednesday's game against the Royals at Fenway Park in what will be his Red Sox debut.

Boston had previously listed May as its scheduled starter for Sunday's game against the Astros, but the right-hander will instead have to wait a few more days beyond that to make his team debut. Lucas Giolito is now slated to take the hill for the Red Sox's final contest of the weekend series with Houston.

Morton will make his first start for the Tigers on Sunday in Philadelphia, Evan Woodbery of MLive.com reports.

Acquired from the Orioles on Thursday in exchange for minor-league lefty Micah Ashman, Morton will step in as the Tigers' new No. 5 starter in place of right-hander Troy Melton, who was moved to the bullpen. Morton will need to be a serviceable innings eater to ensure he sticks in the Detroit rotation for the rest of the season, but after a rough start to the campaign at Baltimore, the veteran righty had been pitching effectively for the past two and a half months. Over his final 14 appearances (11 starts) with the Orioles, Morton logged a 3.62 ERA, 1.32 WHIP and 15.5 K-BB% over 69.2 innings.

The Twins activated Ober (hip) from the 15-day injured list to start Saturday against the Guardians at Progressive Field.

Ober will rejoin the Minnesota rotation after he had been on the shelf since July 2 due to a left hip impingement. Ober built up to five innings and 65 pitches over the course of two minor-league rehab starts, so he could be operating with a light workload restriction Saturday.

Kelly is scheduled to start Saturday's game against the Mariners at T-Mobile Park.

Acquired from the Diamondbacks on Thursday, Kelly will join the Texas rotation as a replacement for right-hander Kumar Rocker, who was optioned to Triple-A Round Rock on Friday. Set to become a free agent this winter, the 36-year-old Kelly will be looking to finish the 2025 campaign on a high note while he aims to secure one last big payday in the offseason. He had been Arizona's top starter this season prior to being dealt, turning in a 3.22 ERA, 1.06 WHIP and 121:38 K:BB over 128.2 innings.

Baz (8-8) took the loss Friday against the Dodgers, allowing five runs on eight hits and two walks in five innings. He struck out eight.

Baz at least managed to register 16 whiffs and fan eight to salvage what was an otherwise poor outing overall. The eight hits allowed were one shy of a season worst, and the 26-year-old right-hander walked multiple batters in his fifth straight start. Baz's impressive run to open the campaign is becoming a distant memory at this point -- he posted a 2.45 ERA through April 25 -- and he'll carry a mediocre 4.79 ERA, 1.33 WHIP and 124:46 K:BB through 124 frames into a scheduled road matchup against the Angels in Anaheim.
