Bieber (elbow) threw seven scoreless innings in a rehab start for Triple-A Buffalo on Friday, allowing six hits and zero walks while striking out four.

The right-hander was dominant in what will almost certainly be his final rehab start as he completes his recovery from Tommy John surgery, firing 64 of 90 pitches for strikes. Per Keegan Matheson of MLB.com, Bieber's fastball has averaged 92.5 miles per hour during his rehab stint, 1.2 mph higher than his last fully healthy campaign in 2022, when he posted a 2.88 ERA, 1.04 WHIP and 198:36 K:BB over 200 innings. Acquired from the Guardians in a trade-deadline deal, Bieber is likely to make his Blue Jays debut -- and first big-league start since April 2, 2024 -- next weekend in Miami. It's not yet clear, however, whether Toronto will shift to a six-man rotation at that point, or bump one of their current starters to the bullpen to accommodate Bieber's return.

Woo (10-7) took the loss against the Mets on Saturday, allowing one run on six hits and two walks with eight strikeouts over six innings.

Woo gave up a run in the third inning but was otherwise sharp, throwing 65 of 101 pitches for strikes while holding the Mets to just one extra-base hit. The 25-year-old notched his 18th quality start and has now worked at least six innings in all 24 of his outings. He'll carry a 3.02 ERA, 0.97 WHIP and 153:28 K:BB across 152 innings into a road matchup with the Athletics next weekend.

McLean earned the win in his MLB debut in Saturday's 3-1 victory over the Mariners, allowing two hits and four walks while striking out eight over 5.1 scoreless innings.

McLean's first big-league start went about as well as the Mets could have hoped, as he fired 55 of 91 pitches for strikes while generating 11 whiffs and limiting the Mariners to four hard-hit balls. Per Anthony DiComo of MLB.com, McLean joined Matt Harvey as the only Mets pitchers to record eight strikeouts and a win in a scoreless debut. According to Ben Krimmel of SNY.tv, Mets manager Carlos Mendoza all but confirmed that the 24-year-old righty will get another turn through the rotation, which will likely fall next weekend in Atlanta. McLean's standing in the rotation beyond that may hinge on how he performs, as Tylor Megill (elbow) is in the midst of a rehab assignment and could displace McLean as the club's fifth starter once he's activated from the injured list.

Cavalli (1-0) picked up the win in Saturday's 2-0 victory over the Phillies, allowing seven hits over seven scoreless innings. He struck out five without walking a batter.

It's been a long road back to the big leagues for Cavalli after he made his debut for the Nationals in 2022 and then dealt with serious arm issues, but Saturday he looked like the potential future ace the club thought it was getting when he was selected 22nd overall in the 2020 Draft. Cavalli racked up 32 called or swinging strikes among his 90 pitches (63 total strikes), and he topped out at 99.7 mph on a first-inning sinker to Bryce Harper while still sitting comfortably in 97-98 mph range against the final batter he faced, Edmundo Sosa. Through three starts since his promotion in early August, the 27-year-old righty has a 2.20 ERA, 1.29 WHIP and 14:4 K:BB over 16.1 innings as he stakes a claim to a 2026 rotation spot. He lines up to make his next trip to the mound on the road next weekend in a rematch with the Phillies.

Walker (4-6) took the loss Saturday as the Phillies fell 2-0 to the Nationals, giving up two runs on six hits and two walks over 6.2 innings. He struck out three.

The veteran righty fired 60 of 94 pitches for strikes en route to his third straight quality start, but Philadelphia's hitters couldn't solve Washington starter Cade Cavalli, giving Walker no margin for error. He appeared set to lose his rotation spot with Aaron Nola (ribs) poised to come off the IL on Sunday, but with Zack Wheeler now dealing with a blood clot in his shoulder, the Phillies will need Walker to remain in his current role. Over six outings since the All-Star break, Walker sports a 2.97 ERA, 1.26 WHIP and 16:4 K:BB in 33.1 innings. He'll look for more run support in his next trip to the mound, which is scheduled to come at home next weekend in a rematch with the Nats.

Lauer (8-2) picked up the win Saturday, allowing one run on four hits and three walks over five innings in a 14-2 rout of the Rangers. He struck out four.

The southpaw tossed an inefficient 102 pitches (63 strikes), but Lauer lasted long enough to get the win and benefit from massive run support by the Blue Jays. He remains undefeated since the All-Star break, going 4-0 over his last six starts with a 2.73 ERA, but Lauer's control may be eroding -- he has an 8:7 K:BB in eight innings over his last two outings. With Shane Bieber (elbow) potentially set to make his Toronto debut next weekend, it's not clear whether Lauer will remain in the rotation, or move into a long-relief role despite his success as a starter.

Corbin (6-9) took the loss Saturday, coughing up seven runs on eight hits and two walks over 2.1 innings in a 14-2 rout at the hands of the Blue Jays. He struck out two.

The veteran lefty held Toronto off the board in the first inning, but a six-run second by the home squad quickly took the suspense out of the game. It was Corbin's shortest and worst start of the season, and while it was the first time since June 23 he's been tagged for more than three earned runs, he appears to be fading -- he's failed to last five innings in three straight trips to the mound. Corbin will take a 4.45 ERA, 1.38 WHIP and 99:40 K:BB through 119.1 innings into his next outing, which lines up to come on the road next week in Kansas City.

Imanaga didn't factor into the decision in Saturday's 3-1 win over the Pirates, allowing one run on three hits and two walks over seven innings. He struck out six.

The southpaw's only real mistake resulted in a Tommy Pham solo shot in the fourth inning, but that was enough to deny Imanaga his ninth win of the season as the Cubs didn't take the lead until the bottom of the eighth inning. He delivered his third straight quality start on 85 pitches (57 strikes), and since returning from a hamstring strain in late June, Imanaga has posted a 3.24 ERA, 0.84 WHIP and dazzling 51:5 K:BB over 58.1 innings. He'll look to keep rolling in his next outing, which is scheduled to come at home next week against the Brewers in a crucial NL Central battle.

Burrows came away with a no-decision in Saturday's 3-1 loss to the Cubs, allowing one run on five hits and two walks over five innings. He struck out four.

The rookie right-hander left the mound after just 68 pitches (45 strikes), and the Pirates may be monitoring his workload given that he threw only 54.2 innings across all levels in 2024 and is already up to 102.2 innings between Triple-A and the majors this season. Burrows was showing signs of fatigue in his prior two outings, surrendering four homers and 10 runs in 9.2 frames, but he didn't give up an extra-base hit to the Cubs on Saturday. He'll look for his first win since June 4 in his next start, which currently lines up to come at home next weekend against the Rockies.

The Phillies placed Wheeler on the 15-day injured list Saturday after he was diagnosed with a blood clot in his right shoulder.

The issue may partially explain why Wheeler has uncharacteristically struggled of late; over his past six starts, he's posted a 4.54 ERA and 1.25 WHIP. According to Jeff Passan of ESPN.com, a timetable for the right-hander hurler's return is unclear, and how soon Wheeler is able to throw again likely depends on how the blood clots respond to treatment. The IL stint no doubt damages Wheeler's run at the NL Cy Young Award, as he had been a top contender after registering a 2.71 ERA and 0.94 WHIP along with an MLB-leading 195 strikeouts over 24 starts spanning 149.2 innings.
