Montero (0-1) took the loss Sunday against the Cardinals, allowing three runs (two earned) on three hits and one walk while striking out three over 4.1 innings.

Making his first start of the season in place of Justin Verlander (hip), Montero was sharp early, retiring 12 of the first 13 batters he faced and holding St. Louis scoreless through four innings. The right-hander ran into trouble in the fifth however, allowing three baserunners, including an RBI single from Pedro Pages that ended his outing. Both inherited runners eventually came around to score, accounting for his final line. Sunday's strong start was an encouraging sign for Montero after he posted a 4.37 ERA and 1.39 WHIP with 72 strikeouts across 90.2 innings in 2025 and he'll look to build on the early success in his next outing against a Miami lineup that has started the season swinging well.

Klassen didn't factor into the decision, allowing two runs on three hits and five walks while striking out four over 2.2 innings Sunday against the Mariners.

Making the start on short notice, Klassen's debut was a mixed bag, with him flashing electric stuff but struggling with command and exiting early. The 24-year-old picked up his first career strikeout in a big spot, fanning Julio Rodriguez with a runner on third to escape the first inning. However, Seattle's patience forced him into a long second inning, where he allowed a two-run single before limiting further damage with another punchout. The right-hander's outing ended in the third after a bunt single and wild pitch put another runner in scoring position. Klassen's fastball (97-98 mph) and hard slider (92 mph) highlight his upside, but sharper control will be necessary for him to stick in a starting role anytime soon.

Castillo did not factor into the decision Sunday against the Angels, allowing four runs (three earned) on six hits and one walk while striking out four over 3.2 innings.

Castillo couldn't find a rhythm in this one, allowing at least two baserunners in every inning he worked and exiting before completing four frames for the first time since 2024. The right-hander ran into trouble immediately, allowing a leadoff double to Zach Neto before Jorge Soler brought him home with an RBI single, and the outing didn't improve much from there. Unlike his dominant Opening Day outing in which he tossed six scoreless innings with seven strikeouts, Castillo failed to fool hitters Sunday and was consistently pitching under pressure. The 33-year-old will look to bounce back in his next scheduled start against Houston, though it presents a tough test against one of the league's most productive offenses early in 2026.

McCullers (1-0) didn't factor into the decision Sunday against the Athletics, allowing three runs on five hits and three walks with four strikeouts across four innings.

McCullers opened the game with four scoreless innings but allowed the first three batters to reach base to begin the fifth and was yanked in favor of Steven Okert, who allowed his two inherited runners to score on a bases-loaded triple by Tyler Soderstrom. McCullers will bring a 3.27 ERA and 13:4 K:BB across 11 innings into his next start Saturday on the road against the Mariners.

Fried (2-0) did not factor into the decision Sunday against Miami, allowing three runs on five hits and three walks over 6.2 innings. He struck out four.

After delivering 13.1 scoreless innings in his first two starts this year, Fried was tagged for a run in the first inning Sunday. However, the left-hander would settle in and hold the Marlins to two runs over his final 5.2 frames, logging his third straight quality start. Fried now sports a 1.35 ERA with a 0.75 WHIP and 14:5 K:BB through 20 innings this season. He's currently in line to face the Rays on the road his next time out.

Martin (2-0) earned the win against the Blue Jays on Sunday, allowing four hits and two walks while striking out six over six scoreless innings.

Martin needed just 85 pitches to log a quality start while limiting the defending American League champions to only singles . The 29-year-old has picked up back-to-back wins to open the season, allowing three runs over 11 innings with a 12:4 K:BB. He lines up for a road matchup against the Royals next weekend.

Bubic (1-1) took the loss Sunday, allowing four runs on four hits and three walks over five innings against the Brewers. He struck out eight.

The left-hander induced 18 whiffs on 96 pitches (58 strikes) on the way to eight strikeouts, but all four of the hits he gave up went for extra bases. Bubic also issued three walks for a second straight start to begin the season. The 29-year-old has a 4.09 ERA, 1.09 WHIP and 12:6 K:BB across 11 innings and lines up to face the White Sox at home next weekend.

Suarez (0-1) didn't factor into the decision Sunday against the Padres, allowing four runs on six hits and two walks over four innings. He struck out two.

Suarez started the day well, holding San Diego scoreless through his first three innings. However, things began to unravel in the fourth, when the left-hander was tagged for three runs. Suarez then gave up a leadoff single in the fifth, eventually resulting in a fourth run, before departing. Suarez's Red Sox tenure has gotten off to a rocky beginning -- he's now given up eight runs on 13 hits across 8.1 innings in his first two starts. Suarez will look to turn things around in his next start, currently slated for next weekend in St. Louis.

Lauer (flu) was far from full strength Sunday and gave up two runs on three hits and three walks in two innings against the White Sox, Ben Nicholson-Smith of Sportsnet.ca reports. Lauer took the loss.

Lauer's start was pushed back one day due to the illness, but it sounds like it still negatively affected his performance. Miguel Vargas plated two runs with a triple in the first inning, and Lauer was fortunate to strand two-thirds of his baserunners in this one. He will presumably be back to full strength for next weekend's matchup at home against the Twins.

Bassitt (0-2) took the loss Sunday against the Pirates, allowing six runs on six hits and two walks in two innings. He failed to record a strikeout.

Following a disappointing Orioles debut that saw him give up four runs to the Rangers, Bassitt was unable to get back on track. The veteran right-hander exhibited a significant lack of control, launching just 32 of his 62 pitches for strikes while laboring his way through only two frames before Baltimore pulled the plug. It's worth mentioning he did sign with the O's fairly late in the offseason, so Bassitt could still be shaking off some rust. He was also hit by a line drive from Oneil Cruz in the second inning Sunday but was able to stay in the game, and his next outing tentatively lines up to take place against the Giants next weekend.
