Kolek is slated to start Saturday's game against the Tigers in Kansas City, Jaylon T. Thompson of The Kansas City Star reports.

Kolek was recalled from Triple-A Omaha on Friday after Michael Wacha (personal) was placed on the paternity list in a corresponding move. Though Wacha is on track to start Sunday's series finale, the Royals will temporarily clear a spot in the rotation for Kolek in order to give rookie Noah Cameron some additional rest between starts. Saturday's outing will mark the Royals debut for Kolek, whom Kansas City acquired from the Padres at the trade deadline. After the trade, Kolek reported to Omaha and logged a 6.63 ERA in 19 innings over five starts before receiving a call-up.

Gray (elbow) threw a about 30 pitches of live batting practice Wednesday, Bobby Blanco of MASNSports.com reports.

The right-hander continues working his way back from the Tommy John surgery with an internal brace that he underwent in July 2024. Gray may need another live session or two before being cleared for a rehab assignment. Assuming he can avoid a setback, the 27-year-old has a good chance of coming off the injured list for a cameo with the Nationals before the end of the season.

The Royals placed Wacha on the paternity list Friday.

Wacha can miss a maximum of three days, according to MLB rules, which could put his scheduled Sunday start in jeopardy. The Royals recalled Stephen Kolek, who's served exclusively as a starter since being acquired by the Royals near the trade deadline, from Triple-A Omaha in a corresponding move. Kansas City hasn't named a starter for Saturday's contest, which is Noah Cameron's normally scheduled turn through the rotation.

The Royals recalled Kolek from Triple-A Omaha on Friday.

Kolek was traded from San Diego to Kansas City near the trade deadline and immediately reported to Omaha. He made five starts with Omaha, posting a 6.63 ERA and a 20:10 K:BB across 19 innings. Kolek steps onto the active roster in place of Michael Wacha, who was placed on the paternity list. Per Anne Rogers of MLB.com the Royals haven't announced a starter for Saturday's game and have Wacha listed as Sunday's starter. Assuming Wacha will be back in time for his scheduled outing, Kolek could pitch in Saturday's game, potentially after Noah Cameron, although Kolek could also get that start if the Royals want to manage Cameron's workload.

The Red Sox selected Tolle's contract from Triple-A Worcester on Friday, Chris Henrique of the Boston Sports Journal reports.

Tolle is set to make his major-league debut Friday at Fenway Park against the visiting Pirates. The left-hander earned his first look in the big leagues after collecting a 3.04 ERA, 0.99 WHIP and 133:23 K:BB over 91.2 innings covering three levels in the minors. Tolle should remain in the Boston rotation for the rest of the season if he pitches well.

The Red Sox released Buehler on Friday, Chris Henrique of the Boston Sports Journal reports.

Buehler was recently demoted to the bullpen and has now been cut loose by Boston after stumbling to a 5.45 ERA, 1.56 WHIP and 84:55 K:BB over 112.1 innings covering 23 appearances (22 starts). The Red Sox will be responsible for what remains of his $18.05 million salary, as well as a $3 million buyout on his 2026 option. Buehler simply hasn't been the same pitcher since his second Tommy John surgery, holding a 5.42 ERA and 17.4 percent strikeout rate since the beginning of the 2024 season.

The Mets selected Tong's contract from Triple-A Syracuse on Friday.

Tong is set to make his major-league debut Friday against the Marlins at Citi Field. The 22-year-old posted a 1.43 ERA and 0.92 WHIP with 179 strikeouts in 113.2 innings covering 22 starts between Double-A Binghamton and Syracuse. Tong isn't guaranteed any starts beyond Friday's debut, but a strong performance could convince the Mets he should stick around alongside fellow rookie Nolan McLean.

Ortiz will remain on non-disciplinary leave for the remainder of the 2025 season, Francys Romero of BeisbolFR.com reports.

Ortiz has been on leave since July 3 as MLB investigates a possible gambling-related offense. The 26-year-old's locker was cleared out at the beginning of August, so Friday's update doesn't come as much of a surprise. Teammate Emmanuel Clase, who's under investigation as well, will not return in 2025 either.

Brown is slated to start Saturday's game against the Cubs.

Colorado is getting German Marquez (biceps) back from the injured list Friday, but Brown will stick around in the rotation with Antonio Senzatela having been moved to the bullpen earlier this week. After bypassing Triple-A, Brown took the loss in his MLB debut Sunday, surrendering four earned runs on five hits and three walks across 3.2 innings. The rookie won't make for an appealing streaming option while taking on the Cubs at hitter-friendly Coors Field.

Pirates manager Don Kelly said that Burrows won't make a start during this weekend's series versus the Red Sox but should be available in relief, Colin Beazley of the Pittsburgh Post-Gazette reports.

Burrows tossed four shutout innings in his most recent start Saturday to lower his ERA to 4.23, but Kelly said the right-hander's turn through the rotation this week will be skipped in an effort to manage his workload. After being limited to 54.2 innings in 2024 following April 2023 Tommy John surgery, Burrows has already doubled that total in 2025 between his stops with Pittsburgh and Triple-A Indianapolis. The Pirates haven't yet discussed shutting him down for the season, but the team's workload management plan could result in him missing another start or two in September. Burrows could also be deployed as a tandem starter with fellow rookie Bubba Chandler, who has covered four innings in each of his first two MLB relief appearances while piggybacking Graham Ashcraft and Carmen Mlodzinski.
