It seems like just yesterday that pitchers and catchers were reporting for Spring Training. But the MLB playoffs are now right around the corner: We’ve reached the final day of the 2023 regular season, while the Wild Card Round begins in a couple of days on Tuesday, Oct. 3. We’ve seen a ton of movement and a ton of postseason tickets punched already this weekend; here’s where the MLB playoff bracket stands entering Sunday, October 1.

MLB playoff bracket: Matchups entering Sunday, October 1

American League

No. 3 Minnesota Twins (87-74; AL Central champs) vs. No. 6 Houston Astros (89-72; third Wild Card)
No. 4 Tampa Bay Rays (98-63; clinched first WC) vs. No. 5 Toronto Blue Jays (89-72; second WC)*

*Note: The Blue Jays hold the head-to-head tiebreaker over the Astros by virtue of winning the season series with Houston

The winner of the 3-6 matchup would face the No. 2 Texas Rangers (90-71; AL West leader) in the Divisional round. The winner of the 4-5 matchup would face the top-seeded Baltimore Orioles (101-60; AL East champs) in the next round.

National League

No. 3 Milwaukee Brewers (91-70; NL Central champs) vs. No. 6 Arizona Diamondbacks (84-77; third WC)*
No. 4 Philadelphia Phillies (89-72; clinched first WC) vs. No. 5 Miami Marlins (84-76; second WC)

*Note: MLB will not make the Marlins return to New York on Monday to finish their rain-postponed game against the Mets, meaning Miami will play only 155 games

The winner of the 3-6 matchup would go on to face the No. 2 Los Angeles Dodgers (99-62; NL West champs) in the Divisional round. The winner of the 4-5 matchup would face the No. 1 Atlanta Braves (104-57; NL East champs) in the next round.
