Perez (elbow) struck out three batters and allowed two earned runs on four hits and no walks over 2.2 innings in his rehab start Sunday with Triple-A Charlotte.

The veteran southpaw took part in his first game action since April 18, after he was diagnosed with a left flexor tendon strain and shut down for an extended period before he resumed throwing in late June. Perez made enough progress in his throwing program to kick off his rehab assignment over the weekend, and he shouldered a healthy workload Sunday, tossing 47 pitches (32 strikes). He's likely to require at least three more rehab starts before he makes his return to the White Sox rotation in late August or early September.

The Orioles activated Povich (hip) from the 15-day injured list Monday.

Povich will start Monday's game in Philadelphia after being sidelined mid-June with hip inflammation. The left-hander got his pitch count up to 86 in his final rehab outing with Triple-A Norfolk this past Tuesday, so he should be able to handle a relatively normal workload against the Phillies.

The Mets selected Hamel's contract from Triple-A Syracuse on Monday.

The right-hander will head to the big leagues for the first time, slotting into the Mets bullpen as a replacement for righty Austin Warren, who was optioned to Syracuse. Over 22 appearances (eight starts) at the Triple-A level this season, Hamel has produced a 4.73 ERA, 1.26 WHIP and 59:15 K:BB in 53.1 frames. He'll likely function as a long reliever for the Mets and is unlikely to see much use in higher-leverage spots while he's up with the big club.

The Twins placed Woods Richardson on the 15-day injured list Monday due to an illness.

Woods Richardson had a scheduled start over the weekend pushed back due to a stomach bug, and he wasn't able to recover from the illness quickly enough to avoid a stint on the IL. The right-hander is eligible to return Aug. 16 and should be ready for activation at that time or shortly after. In the meantime, Jose Urena is likely to continue occupying Woods Richardson's spot in the Twins rotation.

Taillon (calf) struck out one batter and allowed seven earned runs on seven hits across three innings in a rehab start with Triple-A Iowa on Sunday. He also hit two batters.

Making his first appearance at any level since June 29, Taillon didn't issue any walks but lacked command in the 64-pitch outing. Though the right-hander's results left much to be desired, he left the contest feeling healthy and without any reported setbacks with his calf. The Cubs may want to build Taillon up a bit more in another rehab start, but he appears to be closing in on a return from the 15-day injured list. Chicago added Michael Soroka to the back end of its rotation before the trade deadline, but Taillon is likely to slot in as the team's No. 3 starter behind Shota Imanaga and Matthew Boyd once he gets activated.

Bergert is scheduled to start Tuesday's game against the Red Sox at Fenway Park.

The Royals are breaking two of their trade-deadline acquisitions into the rotation for the three-game set in Boston, as lefty Bailey Falter will start Monday's series opener before Bergert makes his team debut Tuesday. The 25-year-old Bergert reached the majors for the first time with the Padres earlier this season and logged a 2.78 ERA, 1.18 WHIP and 34:18 K:BB in 35.2 innings over 11 appearances (seven starts). He could be in line for a brief stint in the Kansas City rotation, as Bergert will be at risk of moving to the bullpen or heading to Triple-A Omaha when Michael Lorenzen (oblique) likely makes his return from the 15-day injured list around the middle of August.

Falter is slated to start Monday's game against the Red Sox at Fenway Park.

The left-hander will step into the rotation for what will be his Royals debut after Kansas City acquired him from Pittsburgh on Thursday in exchange for left-hander Evan Sisk and first baseman Callan Moss. Falter's 15.3 percent strikeout rate on the season is second-lowest among qualified starters in the majors, but he's induced weak contact at a high enough clip to net a 3.73 ERA and 1.18 WHIP over 113.1 innings. His fantasy outlook is unlikely to change dramatically for the worse or better as he heads from Pittsburgh to Kansas City.

Houck (elbow) confirmed Sunday that he will undergo Tommy John surgery around mid-week and said that he's hopeful to resume pitching by the end of the 2026 season, Christopher Smith of MassLive.com reports. "I know the minimum [recovery time from surgery] is probably around the 12-month mark, 12 to the 14-month mark. With that being said, if everything goes right, 12 months from now, plan on being back out there, running out to the mound at Fenway," Houck said. "But you also got to do it the smart way, the correct way...But I'm gonna do everything in my power to get back out there at this time next year and be essentially a trade deadline piece, come back and help in 2026."

According to Smith, Houck noted that he and his surgeon, Dr. Keith Meister, haven't yet discussed whether a late-2026 return is realistic, so the right-hander's tune could change depending on how his surgery goes. Even if Houck meets his goal, he probably won't be available for the big club until September of next season in a best-case scenario, and would likely be working out of the bullpen. Before landing on the shelf May 14 with a right flexor pronator strain, Houck struggled over his nine starts with Boston, logging an 8.09 ERA, 1.69 WHIP and 32:17 K:BB in 43.2 innings. He was cleared to begin a rehab assignment June 18 but was shut down shortly before the All-Star break after a follow-up MRI revealed "significantly worse" damage to his elbow that ultimately prompted Houck's decision to get surgery.

Marquez (biceps) threw a 20-pitch bullpen session Saturday, MLB.com reports.

Marquez was placed on the injured list July 23, but he has made relatively quick progress since. Manager Warren Schaeffer has already stated that Marquez will need a rehab assignment, so he may not be able to return until late August.

King (shoulder) yielded six runs on four hits, one walk and one hit batsman over 3.1 innings in his first rehab start with Triple-A El Paso on Sunday. He struck out five batters.

King served up a pair of home runs and needed 61 pitches to cover his 3.1 frames. He averaged 92.2 miles per hour with his sinker and 92.7 mph with his four-seamer in the outing, which were both down a bit from his season averages. Some rust from King is not a surprise, as he was making his first game appearance since May 18 as he comes back from a pinched thoracic nerve in his right shoulder. Getting stretched out to 61 pitches means King could require just one more rehab start before coming off the 60-day injured list and rejoining the Padres rotation in mid-August.
