Major League Baseball's 2024 regular season is going an extra day, with the Atlanta Braves and New York Mets set for a decisive doubleheader on Monday before the playoffs begin Tuesday.

Forced into the twinbill by weather in the Atlanta area last week, both teams can secure a playoff spot with one win. If the Braves sweep on Monday, that knocks the Mets out of the wild-card picture – with the Arizona Diamondbacks sneaking in.

A Mets sweep would eliminate the Braves in favor of the Diamondbacks (and earn the Mets the No. 2 wild-card spot), and a split will get both the Braves and Mets into the wild-card round.

David Peterson's clutch start puts Mets on doorstep

MILWAUKEE — With two games on Monday and a potential playoff game on Tuesday, there was no bigger time than Sunday for David Peterson to bounce back and ease the burden of the bullpen.

After a bumpy opening inning, the 28-year-old left-hander delivered an encouraging result heading into Monday's doubleheader.

Peterson gave up an infield single to Jackson Chourio in the opening inning before the Brewers put runners on the corners with a walk and a fielder's choice. But Peterson got Eric Haase to wave at a slider for the final out of the inning.

From there, Peterson was nearly unhittable. He only walked two batters across the next six innings, finishing seven scoreless innings with one hit, three walks and eight strikeouts.

"For him to go out there in a must-win for us today, I thought the way he controlled the game, his tempo, I don't think there was any type of pressure," Mets manager Carlos Mendoza said. "He was calm, he was under control and he kept making pitches. It's a good sign because he's one of the guys."
