Sale has been scratched from Monday's start against the Mets due to back spasms, David O'Brien of The Athletic reports.

Atlanta is facing a must-win game after losing the first game of Monday's doubleheader, and they will no longer have their ace available after he felt back spasms Sunday. It will be Grant Holmes starting in Sale's place. When or if Sale might be ready for the wild-card series, should Atlanta qualify, is uncertain. General manager Alex Anthopoulos noted that Sale's injury is a day-to-day situation, which would seem to offer hope he could pitch at some point during the wild-card series, should Atlanta qualify.

Peralta will start Game 1 of the wild-card series for the Brewers on Tuesday, Stephen Watson of Bally Sports Wisconsin reports.

The Brewers don't know their opponent yet, but Peralta is going to get the ball Tuesday regardless of who they play. Peralta collected a 3.68 ERA, 1.22 WHIP and 200:68 K:BB over 173.2 innings covering 32 starts this season. The Brewers have not yet revealed any of their starting pitchers beyond Game 1.

Weathers (5-6) allowed a run on three hits and two walks over 6.1 innings Sunday, striking out six and earning a win over Toronto.

Weathers loaded the bases with no outs in the first inning but escaped the threat unscathed. He didn't allow another runner into scoring position until Luis De Los Santos doubled and later scored in the seventh. At one point, Weathers retired 16 consecutive batters. He posted a 4.02 ERA over 15.2 innings after returning from a three-month stint on the injured list. Weathers finishes the 2024 season with a 3.63 ERA and an 80:24 K:BB through 86.2 frames.

Birdsong (5-6) allowed three runs on four hits and three walks over 4.1 innings Sunday, striking out 11 and taking a loss against St. Louis.

Through four innings, Birdsong had given up one run on a solo shot by Brendan Donovan. The Cardinals then tacked on two more in the fifth inning. Despite recording only 13 outs, Birdsong punched out 11 and racked up 19 whiffs. He generated 12 of those whiffs via the slider. Birdsong ends his rookie season with a 4.75 ERA and 88:43 K:BB through 72 innings. He completed six innings in just one of his 16 MLB starts.

McGreevy (3-0) allowed a run on five hits over eight innings Sunday, striking out six and earning a win over the Giants.

McGreevy let just one Giant reach scoring position through six frames before finally coughing up an RBI single to Brett Wisely in the seventh inning. McGreevy was very efficient, throwing 64 of 91 pitches for strikes, though he forced only seven whiffs. He was impressive during his short rookie season; McGreevy posted a 1.96 ERA and an 18:2 K:BB through 23 frames.

Perez (5-6) took the loss Sunday against Arizona, allowing six runs on eight hits and two walks across 3.2 innings. He struck out three.

Perez's final start of the regular season was lackluster, as the left-hander yielded six runs -- the most he's allowed in a start with the Padres this year. The veteran lefty entered the start having allowed two runs in his previous three starts combined. Perez has a 4.53 ERA with a 107:49 K:BB across 135 innings in 2024.

Pfaadt (11-10) picked up the win Sunday against San Diego, allowing one run on three hits and a walk across 5.1 innings. He struck out nine.

Pfaadt's September has been a roller coaster, as he's yielded four or more runs in three of six starts but given up only five runs in his other three appearances combined. In those three impressive starts, he racked up 31 strikeouts over 18 innings. Pfaadt has a 4.71 ERA and a 185:42 K:BB across 181.1 innings in the regular season, and if the Diamondbacks make the playoffs, he's likely to be part of the team's rotation.

Rea (12-6) was saddled with the loss Sunday, allowing five runs on 10 hits, three walks and a hit batsman over 5.2 innings against the Brewers. He struck out five.

Rea worked past four innings for the first time since Aug 24, but he allowed a season-high 14 batters to reach base. With the Brewers set to host the Wild Card Round of the playoffs starting Tuesday and Rea likely on the outside looking in when it comes to their playoff rotation, he was asked to eat some innings, with the quality being less important than the quantity. The veteran righty finished the regular season with career-high marks in innings pitched (167.2), strikeouts (135) and wins (12).

Morton (8-10) took the loss Sunday against Kansas City, allowing four runs on five hits and two walks across 4.1 innings. He struck out three.

Morton took the loss for the third time in his last four starts and surrendered four runs for a second consecutive outing. All four runs against the 40-year-old came via the long ball, with Michael Massey lifting a three-run homer in the first inning before Hunter Renfroe notched a solo shot in the fourth. Morton ends the regular season with a 4.19 ERA and a 167:65 K:BB across 165.1 innings spanning 30 starts, and his usage Sunday makes it highly unlikely he would be available in the Wild Card Round should Atlanta make the playoffs.

Peterson (10-3) earned the win Sunday, allowing one hit and three walks over seven scoreless innings against the Brewers. He struck out eight.

Peterson saved his best performance for when the Mets needed it most, allowing just a first-inning infield single to Jackson Chourio en route to his second scoreless effort of the year. The eight strikeouts matched his second-highest total of the season, while he dropped his ERA to an impressive 2.90 over 21 starts spanning 121 innings. The Mets still have work to do to make it to the postseason, but should they advance following Monday's doubleheader with Atlanta, Peterson would be required to work on short rest if he were to make an appearance in the Wild Card Round.
