Mahle (0-1) took the loss Saturday against the Yankees, allowing two runs on five hits and one walk in four innings. He struck out five.

The 31-year-old right-hander was coming off an excellent spring, during which he fired 10 shutout frames, but he stumbled in a stiff challenge Saturday against a fearsome Yankees lineup. Shoulder issues plagued Mahle last season with the Rangers, but he was outstanding when healthy with a 2.18 ERA and 1.13 WHIP in 16 regular-season starts. That said, his streaming appeal might be a bit limited in a tough matchup against the Mets in his next scheduled start.

Keller did not factor into the decision in Saturday's 4-2 extra-innings loss to the Mets, allowing three hits and no walks with three strikeouts over six scoreless innings.

Keller was extremely efficient, needing just 77 pitches to blank the Mets over six innings. It was an encouraging outing for the 29-year-old, who has logged 175-plus frames in each of his past three seasons. He lines up for a home matchup against the Orioles next weekend.

Peterson did not factor into the decision in Saturday's 4-2 extra-innings win over the Pirates, allowing six hits and two walks with three strikeouts over 5.1 scoreless innings.

Peterson threw 51 of 76 pitches for strikes while generating eight whiffs, exiting two outs shy of a quality start in the sixth inning. The southpaw earned an All-Star nod in 2025 before stumbling to a 6.34 ERA over 59.2 innings in the second half. He's coming off a career-high 168.2 innings overall and should benefit from backing by a strong Mets offense. The 30-year-old lines up for a road start against the Giants next week.

Wacha took a no-decision Saturday against Atlanta, allowing no runs on three hits and one walk in six innings. He struck out seven.

Wacha performed about as well as one could have expected in his season debut against a tough Atlanta lineup, scattering three singles across six shutout frames. The veteran right-hander had also been in line for the win, but Carlos Estevez imploded in the ninth inning by yielding six runs and blowing the save. Wacha threw 80 pitches Saturday, so he'll be looking to increase his pitch count in his next scheduled start at home versus the Brewers.

Lorenzen did not factor into the decision in Saturday's 4-3 loss to the Marlins, allowing three runs on seven hits and no walks with four strikeouts over 4.1 innings.

Lorenzen entered the fifth inning with a two-run lead but couldn't get out of the frame, exiting at 93 pitches after giving up a two-run homer to Liam Hicks. The 33-year-old signed a one-year, $8 million deal in January and should hold a secure spot in the rotation on a lowly Rockies club. He lines up for a tough home matchup against the Phillies next weekend.

Singer allowed three runs on five hits and two walks across four innings in Saturday's 6-5 win over the Red Sox. He struck out five.

Singer dealt with a blister 10 days ago in a spring start against the Rockies, but he didn't miss any time with the issue. However, his velocity was notably down against Boston on Saturday, averaging just 90.5 mph with his sinker and 89.7 mph with his fastball. The veteran right-hander's next scheduled start should come next weekend on the road against Texas.

Perez did not factor into the decision in Saturday's 4-3 win over the Rockies, allowing three runs on five hits and one walk with eight strikeouts over seven innings.

Perez surrendered two home runs but was otherwise effective, throwing 59 of 93 pitches for strikes and generating 17 whiffs. According to Christina De Nicola of MLB.com, it marked just the third time in 40 outings that the 22-year-old reached the seventh frame. The breakout candidate posted a 4.25 ERA, 1.05 WHIP and 105:32 K:BB across 95.1 innings last season and flashed his upside Saturday. He'll face a tougher test on the road against the Yankees next weekend.

Gray allowed four runs (three earned) on six hits and one walk across four innings in Saturday's 6-5 loss to the Reds. He struck out five.

Making his regular-season debut with the Red Sox, Gray labored through the first inning, needing 35 pitches to get through the frame while allowing two runs. Gray allowed at least one run in each of the first three innings and served up a solo home run to Sal Stewart in the third. The right-hander will look to be more efficient in his next scheduled start against the Padres next weekend.

Nola allowed three runs on five hits and two walks across five innings in Saturday's 5-4 loss to the Rangers. He struck out seven.

Nola was burned by the long ball, surrendering a solo shot to Corey Seager in the first inning before Jake Burger took Nola deep for a two-run home run in the third. Nola was let off the hook for the loss when the Phillies rallied to tie the game in the ninth inning. Nola's next start is lined up for next weekend in Colorado.

Gaddis (forearm) allowed one walk while striking out one batter in a scoreless inning in his rehab assignment with Triple-A Columbus on Saturday, Tim Stebbins of MLB.com reports.

Gaddis opened the regular season on the 15-day injured list due to a right forearm strain that cropped up in early March. He got some games under his belt toward the tail end of spring training, and the 27-year-old right-hander could be back in the majors by mid-April depending on how his rehab assignment goes. Across 73 regular-season games in 2025, Gaddis posted a 3.11 ERA, 1.19 WHIP, three saves (in seven attempts) and a 73:21 K:BB across 66.2 innings.
