The New York Mets and Atlanta traded celebrations on the same Truist Field on Monday, when the wild National League wild card race was finally decided.

The NL needed an extra day and two postponed games to settle things, but when Atlanta beat the Mets 3-0 to salvage a split in a doubleheader pushed back because of Hurricane Helene, Arizona was left out.

All three finished the regular season at 89-73, but the Diamondbacks lost a tiebreaker after losing season series to Atlanta (5-2) and the Mets (4-3).

“We’re in, and anything can happen,” manager Brian Snitker said after Atlanta secured a playoff berth for the seventh straight season.

The Diamondbacks can lament the final eight days of the season — they lost an 8-0 lead in a 10-9 loss at Milwaukee on Sept. 22 and lost home series to San Francisco and San Diego in the last week.

The Mets won 19 of their final 28 games, the best record in the majors, to reach the playoffs for the second time since 2016. Atlanta was 16-12 in that stretch and the Diamondbacks were 13-15. The Mets were 11 games under .500 open June 2.

Milwaukee and San Diego not only will have the home field field advantage, they will have the freshness edge after the Mets and Atlanta played 18 innings Monday.

Players to watch/things to know

New York Mets: SS Francisco Lindor gave Shohei Ohtani a run for the NL MVP award with 33 homers, 91 RBIs and 29 stolen bases. He pushed the Mets into the playoffs with a two-run homer in the ninth inning of the 7-6 victory in the first game at Atlanta on Monday.

1B Pete Alonso had 34 homers and 88 RBIs in his walk year, and RF Brandon Nimmo had 90 RBIs and 23 homers, including big ones in the final week stretch against Philadelphia and Atlanta.

The Mets had four double-digit winners, led by lefty Sean Manaea, who tied his career high with 12 wins and had a carer-best 3.47 ERA after signing a two-year, $28 million deal last winter that includes a player option.

Milwaukee: SS Willy Adames set career highs in almost every offensive category — 32 homers, 112 RBIs, 33 doubles, 21 stolen bases — as he prepares to hit the free agent market this winter. 1B Rhys Hoskins has 26 homers and 82 RBIs in his first (and maybe only season) here.

Rookie Jackson Chourio made a late run at the Rookie of the Year award, finishing with 21 homers, 22 stolen bases and 79 RBIs. Chourio, who signed an eight-year, $82 million deal at the winter meetings, is the only player in major league history with a 20/20/20 three peat — 20 homers and stolen bases at age 20.

The Brewers made the playoffs for sixth time in seven seasons under first-year manager Pat Murphy. He used 17 starting pitches, only three of whom make more than 14 starts. They have 64 defensive runs “saved,” according to Fangraphs, tied with the Los Angeles Dodgers for the most in the league, and have 217 stolen bases.

No. 5 seed Atlanta (89-73) vs No. 4 seed San Diego (93-69)

Wednesday: Atlanta at San Diego ESPN2, 7:30 pm ET

Thursday: Atlanta at San Diego, ESPN, 6 pm ET (if necessary)

Season series: San Diego won, 4-3. The Padres won three of four in Atlanta but lost two of three at home before the All-Star break. Chris Sale won both his starts agains the Padres, giving up one run in 12 innings.

Players to watch/things to know

Atlanta: Sale is the overwhelming favorite to win the NL Cy Young Award after going 18-3 with a league-leading 2.38 ERA in his first season in Atlanta, but his health is a major issue entering the playoffs.

Sale was scratched from his scheduled start in the second game of the Monday doubleheader against the Mets because of back spasms, and manager Snitker said he is unlikely to pitch against the Padres, a huge blow even for a team whose starters led the NL with a 3.56 ERA.

DH Marcell Ozuna (39 homers, 104 RBIs) and 1B Matt Olson (29/98) were two of the only three players with least 450 at-bats for the injury-ravaged Braves. RF Ronald Acuna, the 2023 NL MVP, has been out with a knee injury since May and 3B Austin Riley (19 homers) will miss the postseason with a broken hand suffered Aug. 18.

San Diego: 3B Manny Machado (29 homers), LF Jurickson Profar (24), CF Jackson Merrill (24) and RF Fernando Tatis Jr. (21) lead a balanced offense that got a bump when DH/IF Luis Arraez (.318) was acquired from Miami to fill the leadoff hole May 4. Arraez won his third batting title in three seasons.

Offseason acquisitions RHPs Dylan Cease and King anchor a solid rotation, and RHP Roberto Suarez had a career-high 36 saves in his first season as a closer. Merrill is a top candidate for NL Rookie of the Year, adding 90 RBIs.

The Padres are 43-19 since July 19, the best record in the majors over that span by three games. The Dodgers held them off in the division by going 41-23 in that same stretch. San Diego does a lot well. They lead the NL in batting average (263), are fifth in ERA (3.86), tied for first in shutouts (16) and fourth in fielding percentage.
