Trey Yesavage SP | TOR
Blue Jays' Trey Yesavage: Looks good in rehab start
Yesavage (shoulder) allowed one run on one hit and one walk over 2.2 innings for Single-A Dunedin on Friday. He struck our four.
The young right-hander began a rehab assignment after a shoulder impingement cut short his spring, and Yesavage was able to throw 44 pitches while showing velocity that was nearly at his 2025 levels. He appears to be the closest to returning of the Blue Jays' injured starters, with Jose Berrios (elbow) and Shane Bieber (forearm) also working their way back. The next step for Yesavage will be determined in a couple of days once the organization sees how his arm bounced back from Friday's outing.

Reid Detmers SP | LAA
Angels' Reid Detmers: Spins 6.2 shutout innings
Detmers didn't factor into the decision Friday against the Mariners, allowing three hits and four walks with four strikeouts across 6.2 scoreless innings.
Detmers threw just 11 first-pitch strikes to his 26 batters faced but worked around his four free passes while firing 104 pitches. The Angels haven't eased Detmers back into the rotation at all, letting him throw 199 pitches across two starts to open the 2026 campaign after he spent last season in the bullpen. Detmers hasn't factored into the decision in either start and will carry a 2.38 ERA, 1.15 WHIP and 13:4 K:BB over 11.1 innings into his next start Wednesday against Atlanta.

Bryan Woo SP | SEA
Mariners' Bryan Woo: Allows one hit in no-decision
Woo didn't factor into the decision Friday against the Angels, allowing just one hit and one walk with six strikeouts across seven shutout innings.
The lone hit Woo allowed was an infield single to Oswald Peraza in the third inning, and Woo eventually erased him by picking Peraza off first base. While Woo dazzled across seven scoreless frames, Reid Detmers nearly matched him, holding the Seattle offense to three hits and four walks across 6.2 shutout innings. The game required an extra inning after going scoreless through nine innings. Woo doesn't have any wins to show for his excellent start to the 2026 campaign; he's registered a 1.38 ERA and 15:2 K:BB across 13 innings. His next start is slated to come Wednesday against the Rangers.

Merrill Kelly SP | ARI
Diamondbacks' Merrill Kelly: Dazzles at Reno
Kelly (back) allowed two hits and two walks while striking out two over five scoreless innings for Triple-A Reno on Friday.
Kelly made his first -- and perhaps only -- rehab start Friday and threw 72 pitches (40 strikes). That puts him in range to be activated next week. If Arizona chooses to bring him back, Kelly's five-day schedule lines him up to pitch next Wednesday against the Yankees in New York.

Colin Rea SP | CHC
Cubs' Colin Rea: Works in relief of injured starter
Rea allowed one run on four hits across 3.1 innings of relief in Friday's 4-1 loss to the Guardians. He walked one and struck out four.
Rea entered in the second inning after starter Cade Horton (forearm) departed early. After the game, the Cubs announced that Horton will be headed to the injured list, which will open up a rotation spot at least temporarily. Rea made 27 regular-season starts for Chicago last year and has 103 career starts at the MLB level, so he certainly has the experience to slide in if needed. Ben Brown is also an option to make starts, though the Cubs have not announced their plans for Horton's spot yet.

Eury Perez SP | MIA
Marlins' Eury Perez: Can't find plate in Friday's loss
Perez (0-1) took the loss Friday, giving up four runs on two hits and six walks over four innings as the Marlins were downed 8-2 by the Yankees. He struck out four.
The 22-year-old right-hander's command within the strike zone was just as bad as his control, as both hits he allowed went for extra bases, including an Aaron Judge two-run homer in the first inning. Perez has had a bumpy start to the season, posting a 5.73 ERA, 1.27 WHIP and 12:7 K:BB through 11 innings over two outings. He'll try to turn things around in his next trip to the mound, which lines up to come at home next week against the Reds.

Tyler Mahle SP | ATL
Giants' Tyler Mahle: Loses again Friday
Mahle (0-2) allowed five runs on eight hits and two walks while striking out four over five innings to take the loss versus the Mets on Friday.
Three of the five runs on Mahle's line came from long balls, as Marcus Semien hit a two-run blast and Francisco Alvarez added a solo shot in the fourth inning. Mahle allowed just five homers over 86.2 innings across 16 regular-season starts last year while also maintaining a 2.18 ERA, 1.13 WHIP and 66:29 K:BB. He typically doesn't have too much trouble with homers despite giving up plenty of contact in the air. He's allowed seven runs while posting a 9:3 K:BB over nine innings across two starts this season. Mahle is projected to make his next start at home versus the Phillies.

Nolan McLean SP | NYM
Mets' Nolan McLean: Impresses in second start
McLean (1-0) allowed two runs (one earned) on one hit and two walks while striking out four over 5.1 innings to earn the win over the Giants on Friday.
McLean was perfect through five innings. He got into a bit of trouble in the sixth, but the Mets had put up five runs before McLean faltered, and Brooks Raley was able to finish off the frame despite allowing one inherited runner to score. Through 10.1 innings over two starts, McLean has allowed just four runs (three earned) while posting a 12:4 K:BB. The 24-year-old right-hander is looking promising so far after impressing with a 2.06 ERA, 1.04 WHIP and 57:16 K:BB over 48 innings in eight regular-season starts at the tail end of 2025. His next start is projected to be at home versus the Diamondbacks.

Jeffrey Springs SP | ATH
Athletics' Jeffrey Springs: Sharp in win over Astros
Springs (1-0) allowed one run on two hits and a walk while striking out seven over six innings to earn the win over the Astros on Friday.
Springs collected his first quality start of the season and showed some improvement from his season debut. He threw 66 of 103 pitches for strikes in this outing, limiting the damage to a Yordan Alvarez sacrifice fly in the third inning. Springs has a 9:4 K:BB with three runs allowed over 11.1 innings across two starts this season. He had a decent 2025, posting a 4.11 ERA, 1.21 WHIP and 138:54 K:BB over 171 innings across 32 appearances (30 starts). Springs should be firmly in the rotation for the Athletics this season, and he could rebound in the strikeout department since his 7.3 K/9 last year was a career low. The southpaw is projected to make his next start on the road versus the Yankees.

Cristian Javier SP | HOU
Astros' Cristian Javier: Struggles against Athletics
Javier (0-1) took the loss Friday versus the Athletics, allowing six runs on six hits and five walks while striking out two over 3.2 innings.
Javier ran into trouble in the third inning and then found more of it in the fourth before he was pulled from the game. He threw just 44 of 82 pitches for strikes, though he was able to keep the ball in the yard after allowing two homers to the Angels in his season debut. Javier's command is looking like a big problem -- he has a 3:9 K:BB with two hit batsman over 8.1 innings across his two starts this season. He's also given up 12 runs, but much of that is self-inflicted damage from putting too much traffic on the bases. The right-hander won't catch a break in his next scheduled outing, which is projected to be on the road in Colorado.
