It took an extra day and a memorable doubleheader between the Atlanta Braves and the New York Mets, but the entire MLB playoff bracket has officially been completed.

Here’s what you need to know:

• The playoffs begin Tuesday with two Wild Card Series in each league.
• The New York Yankees are the top seed in the AL playoffs for the first time since 2012, while the Los Angeles Dodgers are the top seed in the NL for the fifth time since 2017.
• The Cleveland Guardians, the second seed in the AL, and Philadelphia Phillies, the second seed in the NL, have also bowed out of the Division Series.
• The Mets clinched a spot Monday thanks to a two-run homer by Francisco Lindor in an epic 8-7 win over the Braves in Game 1. The Braves then turned around and won Game 2, eliminating the Arizona Diamondbacks.
• The Tigers – who were tied with the Angels for the longest playoff drought – are in the postseason for the first time in a decade, while the Royals are in the playoffs for the first time since 2015.
• After this best-of-three series, the Division Series round begins on Saturday, October 5.

The Athletics‘s immediate analysis:

Who should be the World Series favorite?

Monday’s FanGraphs predictions favored the Phillies, giving them an 18 percent chance of winning it all. The betting markets such as the Phillies, Yankees and Dodgers.

But after a regular season in which no team won 100 games for the first time since 2014, the postseason field is wide open. Last year’s two League Championship Series featured three wild-card teams, and the World Series featured the fifth seed from the AL (Rangers) and the sixth seed from the NL (Diamondbacks). That came after the sixth seed Phillies reached the World Series in 2022, the first year the postseason was expanded to include three wild cards in each league.

How about a stealth favorite?

The field certainly won’t like this, but what about the Astros?

They have the best record in baseball since April 27 and their pitching staff has the lowest ERA since May 1.

The Astros can extend their streak of ALCS appearances to eight, which would tie the Atlanta Braves (1991 to 1999) for the most consecutive LCS appearances in history.

Best storyline from the Wild Card series?

Tigers manager AJ Hinch returns to Houston, where he guided the Astros to a World Series championship in 2017 before being suspended and fired in 2020 in the wake of the club’s sign-stealing scandal.

Hinch returned to management in Detroit in 2021 and, after three straight losing seasons, has helped complete a rebuild and lead the Tigers back to October after a decade-long drought.

“There’s nothing better than baseball in October,” Hinch said Monday at Minute Maid Park in Houston. “And I got to experience a lot of it, and a lot of it in this building.

“It’s the best month to play…and baseball in October really defined this building and this place for a while. We all watch baseball. When you’re not in it, you’re glued to the TV. If you are in it, the months of September and October have often passed here.”

Disturbed watch

Feel free to quibble over the term “upset” in a three-game series between two postseason teams.

But watch out for the Mets.

The biggest question was whether the Mets could survive the final week of the season. But forget that. They are here now. And they brought the memes, from Grimace to “OMG” to 24-35 in early June.

The Mets went 65-37 over their next 102 games to clinch a playoff spot. It was the best baseball record during that period.

They now take on the Milwaukee Brewers in a series that pits David Stearns, the Mets president of baseball operations, against his old team.

Second chance, 10 years later

Ten years ago, the Orioles faced the Royals in an unexpected American League Championship Series matchup. The series was known at the time for its contrasting managers: Buck Showalter of the Orioles and Ned Yost of the Royals.

The Royals won the series in four games, and 10 years later, only one player remains from both teams: Royals catcher Salvador Perez, who turned 34 in May.

Players to watch?

We’ll have to wait until the Division Series round to see the presumptive MVP favorites: Aaron Judge of the Yankees in the AL and Shohei Ohtani of the Dodgers in the NL. Juan Soto of the Yankees, Bryce Harper of the Phillies, Jose Ramirez of the Guardians and Mookie Betts of the Dodgers will also get four days of rest.

But there will still be plenty of star power on display on Tuesday. The playoffs begin Tuesday with two Wild Card Series in each league, giving some of the biggest names a shot at playoff glory.

• Royals shortstop Bobby Witt Jr. is making his playoff debut and he’s paired with Orioles shortstop Gunnar Henderson, who went 6-for-12 with a homer in last year’s ALDS loss to the Rangers.
• Mets shortstop Francisco Lindor, who will likely finish second in the NL MVP voting, will return for his second postseason go-around in New York after making the postseason four times in Cleveland.
• Tigers ace Tarik Skubal – the likely AL Cy Young winner after posting a 2.39 ERA in 31 starts – will make his postseason debut Tuesday against the Astros in Houston. He will face Framber Valdez, who finished 15-7 with a 2.91 ERA.
• We’ll also see a pair of young Jacksons: Jackson Merrill, the Padres’ 21-year-old center fielder and NL Rookie of the Year candidate, and Jackson Chourio, the Brewers’ 20-year-old outfielder.
