Mark Vientos and Brandon Nimmo keyed another late comeback in New York’s electric run through the National League playoffs, helping the Mets break through for five runs in the eighth inning against a pair of All-Star relievers as they rallied past the Philadelphia Phillies 6-2 on Saturday in Game 1 of their Division Series.

The Mets had been stymied by Phillies ace Zack Wheeler, held to just one hit while trailing 1-0 and unable to muster any real scoring chances over the first seven innings.

With Wheeler lifted after nine strikeouts and a startling 30 swings-and-misses over 111 pitches, the Mets — whose whirlwind week included a victory in a makeup doubleheader at Atlanta to clinch a postseason spot and three games in the Wild Card Series at Milwaukee — pounced against losing pitcher Jeff Hoffman and fellow reliever Matt Strahm in the eighth.

In true New York fashion this October, the Mets had to rally, not just on the scoreboard, but on a gut-check in each each at-bat.

Francisco Alvarez hit a leadoff single against Hoffman before three straight batters reached base after facing 0-2 counts. Francisco Lindor worked a walk from his 0-2 count and Vientos followed with a tying single. Nimmo laced a go-ahead single off Strahm past a drawn-in infield for the 2-1 lead.

Pinch-hitter J.D. Martinez added an RBI single and Pete Alonso, who hit a go-ahead, three-run homer in the ninth inning in the Wild Card Series clincher in Milwaukee, and Starling Marte each added a sacrifice fly in the eighth for a 5-1 lead that sent the Mets into a frenzy in the dugout.

Leave it to the Mets to win this one late — they have scored 18 runs in the eighth and ninth innings in six games since Monday. New York joined the 1980 Phillies and 1999 Mets as the only teams to win consecutive playoff games after trailing in the eighth inning or later.

The Phillies were left reeling headed into Sunday’s Game 2 after they wasted their ace’s splendid outing.

Guardians 7, Tigers 0

Lane Thomas hit a three-run homer in a five-run outburst before Detroit got an out, and Cleveland unleashed its lights-out bullpen to complete a four-hitter in a 7-0 win over the Tigers in an AL Division Series.

Thomas’ shot — on his first career postseason swing — helped the Guardians cool off the Tigers, who stormed into the playoffs with a second-half surge before sweeping AL West champion Houston in the wild-card round.

Tanner Bibee pitched 4 2/3 innings before Guardians manager Stephen Vogt swung the door open to baseball’s best bullpen to finish off the Tigers. Relievers combined for 4 1/3 hitless innings to finish the largest shutout victory margin in Cleveland postseason history.

Detroit struck 13 out times and didn’t get a runner past first in the final four innings.

Cleveland’s bullpen was as advertised. Rookie Cade Smith (1-0) replaced Bibee and struck out all four batters. Tim Herrin took care of the seventh, Hunter Gaddis the eighth, and Emmanuel Clase, who led the AL with 47 saves, worked the ninth.

David Fry added a two-run, sixth-inning double for the AL Central champion Guardians, who were unaffected by not playing for almost a week with a first-round bye.

Game 2 is Monday, when the Tigers will turn to Tarik Skubal, the favorite to win the AL Cy Young Award, to try and even the best-of-five series.

Yankees 6, Royals 5

Alex Verdugo hit a tiebreaking single in the seventh inning and saved at least one run with a sliding catch along the left-field line, boosting the New York Yankees over the Kansas City Royals 6-5 on Saturday night in their AL Division Series opener.

New York’s Gleyber Torres and Kansas City’s MJ Melendez hit two-run homers in a back-and-forth game in which the Royals wasted leads of 1-0, 3-2 and 5-4 and the Yankees failed to hold 2-1 and 4-3 margins. It was the first postseason game with five lead changes, according to the Elias Sports Bureau.
