Mahle (shoulder) is expected to make a two-inning rehab start for Triple-A Round Rock on Tuesday, MLB.com reports.

Mahle has been on the shelf since June 15 due to a right shoulder strain and has slowly been building back up, but he'll take a major step forward in the recovery process by kicking off a rehab assignment Tuesday. At this stage of the season, Mahle may not have enough time to get fully stretched out for a traditional starting role, though he appears on track to pitch for the Rangers in some capacity later on in September.

Misiorowski allowed three runs on six hits and one walk while striking out four batters over 4.1 innings in a no-decision against Philadelphia on Monday.

Misiorowski was less than dazzling against the Phillies, though he did get 12 whiffs among his 73 pitches. The rookie hurler did fine with just one run allowed until the fifth inning, but in that frame the Phillies got to him for two runs on two hits and a walk while he retired just one batter. Misiorowski has faded over his past four appearances, allowing 14 earned runs over 14.2 innings despite a 22:8 K:BB over that span. He'll look to get back on the track in what could be a favorable matchup next time out, as he's in line to face the Pirates in Pittsburgh this weekend.

Walker allowed five runs on seven hits and two walks while striking out two batters over four innings in a no-decision against Milwaukee on Monday.

Walker fell behind quickly, allowing four runs over his first two innings. He gave up just one more run across his final two frames, and Philadelphia's offense exploded late to take Walker off the hook for a loss. Nonetheless, this wasn't a promising start by the right-hander -- the five runs he yielded were a season high, and four of the seven hits (two doubles and two homers) he allowed went for extra bases. Walker hasn't pitched more than five innings in any of his past three starts, posting a 7.71 ERA, 1.86 WHIP and 10:6 K:BB across 14 frames during that span. He'll look to do better in his next start, which is tentatively slated to take place in Miami this weekend.

Civale allowed a hit and no walks while striking out four over three scoreless innings Monday against Atlanta.

Civale impressed in his Cubs debut, tossing three scoreless innings to help set the stage for a comeback win. The right-hander was claimed off waivers from the White Sox on Sunday after logging a 5.26 ERA and 1.37 WHIP over 89 innings (18 starts) between Chicago and Milwaukee. Though he's worked as a starter in his career, the Cubs plan to use him out of the bullpen down the stretch.

Rea did not factor into the decision Monday, allowing three runs on five hits and three walks over four innings against Atlanta. He struck out three.

Rea was unimpressive Monday, failing to get through five innings and allowing plenty of traffic on the bases. The right-hander has shown signs of wearing down lately, pitching to a 5.03 ERA and 1.53 WHIP over 34 innings in his last seven outings. He's slated to take the ball again Sunday against Washington.

Nelson allowed three runs on four hits and a walk while striking out seven over six innings in a no-decision versus the Rangers on Monday.

This was Nelson's third straight quality start, and he's allowed seven runs over 18 innings in that span. While he's not blowing away opposing hitters, he's been steady and reliable with passable strikeout totals in much of his time as a starter. Overall, he's posted a 3.57 ERA, 1.05 WHIP and 115:33 K:BB across 131 innings through 29 appearances (19 starts) this season. Nelson is projected for a home start versus the Red Sox this weekend.

Strider did not factor into the decision in Monday's extra-inning loss to the Cubs, allowing three runs on five hits and three walks with a strikeout over five-plus innings.

Strider turned in a passable but underwhelming outing Monday, managing just one strikeout -- his lowest mark of the season. The right-hander has shown flashes of effectiveness but hasn't come close to regaining the dominance he displayed prior to injuring his right elbow early in 2024. Through 19 starts this season, the 26-year-old carries a 4.97 ERA and 1.39 WHIP across 101.1 innings, with a 9.4 K/9 sitting well below his peak production.

Corbin allowed five runs on five hits and a walk while striking out five over 5.2 innings in a no-decision versus the Diamondbacks on Monday.

Corbin gave up three solo home runs over the first two innings. He hadn't allowed multiple homers in a start since May 25 versus the White Sox, though he has now given up seven long balls over his last six starts. Corbin posted a 7.17 ERA over 21.1 innings in August and is off to a similarly rough beginning in September. For the season, he's at a 4.48 ERA, 1.35 WHIP and 114:44 K:BB through 136.2 innings over 26 starts. His next start is projected to be at home versus the Astros this weekend.

Gray (12-8) took the loss Monday, allowing seven runs on 10 hits and three walks over six-plus innings against the Athletics. He struck out five.

Gray worked through three scoreless innings Monday before things unraveled, surrendering two home runs in the fourth inning, another in the sixth, and then having two more runs charged to him without recording an out in the seventh frame. The long ball has plagued the right-hander all season, as he carries a 1.31 HR/9 and has allowed multiple homers in six different starts. The veteran now owns a 4.43 ERA and 1.22 WHIP across 158.1 innings in 28 starts this year.

Morales (3-0) earned the win Monday, allowing two runs on five hits and a walk over 5.2 innings against the Cardinals. He struck out eight.

Morales kept his strong run going Monday, striking out a career-high eight batters while picking up his third win. The 22-year-old has impressed with the Athletics, logging a 1.59 ERA and 0.99 WHIP across 28.1 innings in six appearances (five starts). With such a strong debut season in 2025, he's making a compelling case to earn a full-time rotation spot heading into 2026.
