MLB Wild Card Series 2026 Calendar: Dates and teams for every game in the first round of the postseason

The 2026 MLB postseason begins on September 29 with four best-of-three Wild Card Series. Ten teams have already secured postseason berths, with the Tampa Bay Rays locking up the American League's top seed and the Milwaukee Brewers clinching the best record in MLB. The first confirmed Wild Card matchup will see the New York Yankees host the Boston Red Sox at Yankee Stadium.

Game 1 takes place on Tuesday, September 29, followed by Game 2 on September 30, and a potential Game 3 on October 1. Boston will turn to rookie left-hander Payton Tolle, while Aaron Judge is attempting to return from injury for New York. Remaining postseason matchups will be determined by the final regular-season standings.
