Postseason Watch: Bracket, tiebreakers and more

5:19 AM UTC

Monday's MLB action included a pair of contests between division rivals in playoff contention -- and both games featured huge offensive performances from the visitors.

The Astros rallied from an early 3-0 deficit against the Rangers, putting up a six-run seventh inning to power themselves to a 13-6 win in Arlington and move into a virtual tie for first place in the American League West. In the AL Central, rookie Royce Lewis hit his third grand slam in eight games as the Twins routed the Guardians 20-6 to extend their division lead.

And on the National League side, Justin Steele pitched a gem for the Cubs, tossing eight scoreless innings with 12 strikeouts in Chicago's 5-0 shutout of the Giants -- a key win for the North Siders in the NL Wild Card race.

While a lot can happen in the standings between now and when the postseason starts on Oct. 3, here is what the playoff picture looks like heading into Tuesday's games.

Reminder: As part of the collective bargaining agreement made with the Players Association before the 2022 season, Major League Baseball expanded the postseason field from 10 to 12 teams. Both the AL and NL now have three Wild Card berths (up from two prior to 2022), with the top two seeds in each league receiving first-round byes. The other teams will pair up for the best-of-three Wild Card Series, in which all three games will be played at the home of the higher seed, with winners advancing to the Division Series.

TIEBREAKERS

Since 2022, all ties in the standings -- for a division title or Wild Card spot, or to determine playoff seeding -- have been determined solely by a series of mathematical tiebreakers, rather than on the field. A full breakdown of the current methodology can be seen here, but to summarize, the top three elements are, in order: head-to-head record, intradivision record (i.e. within the same division) and then record against opponents in the same league but a different division.

See here for a full breakdown of the key potential tiebreaker scenarios for each contender in 2023.

Here is a look at three examples of how tiebreakers could come into play:

  • In the AL West race, the Mariners have already clinched a tiebreaker over the Astros by winning eight of the teams' first 10 matchups, with three to go.
  • The Blue Jays (1-2 vs. Texas) would need to win at least three of four over the Rangers from Sept. 11-14 in Toronto to claim the tiebreaker in case they finish deadlocked for the last AL Wild Card spot.
  • The Giants have locked up tiebreakers with the Brewers, Reds and Phillies, which could come into play for either the final NL Wild Card spot or seeding. San Francisco also needs to win one of two from Arizona (Sept. 19-20) to clinch the advantage over the D-backs.

WHAT YOU NEED TO KNOW

Who has clinched: Nobody

Who is next: The Braves (90-46) have a magic number of five to clinch a postseason berth and a magic number of 12 to clinch the NL East. The Dodgers (84-52) have a magic number of 12 to clinch the NL West title.

Heading down: The Rangers' slide continued with Monday's home loss to the Astros. Texas dropped two of three games over the weekend to the Twins and is 4-6 in its past 10 games, the worst mark of any AL contender.
