NEW YORK — Jerar Encarnación was called up to the major leagues, and Miami Marlins teammate Sandy Alcantara made a promise to the 24-year-old.

“I told him if you get a hit or a homer, I’m going to buy something,” the pitcher recalled saying on the way back to the team hotel Friday night.

Inserted into the depleted Marlins’ starting lineup, Encarnación made a spectacular major league debut with a go-ahead, seventh-inning grand slam for his first hit. He also threw out a runner at third base from right field and stole a base, lifting Alcantara and Miami over the New York Mets 6-2 Sunday.

Call it a suitable debut.

“Let’s go — get my clothes,” a smiling Encarnación said he told Alcantara after game.

“Anything he wants,” the pitcher responded.

Alcantara first met Encarnación in 2014 in San Isidro, Dominican Republic. Encarnación signed with the Marlins the following year, started in the minors in 2016 and was their No. 16 prospect heading into the 2020 season after his grand slam off Washington’s Sterling Sharp won the Arizona Fall League championship.

Encarnación stalled following a year of minor league ball canceled by the coronavirus pandemic and was Miami’s No. 22 prospect after a 2021 in which he hurt his right knee while hitting a metal pole when chasing a foul ball and then was hit on his left hand by a pitch.

He began 2022 at Double-A Pensacola, homered in his Triple-A debut for Jacksonville on May 17 and was brought up to the big leagues Friday after hitting 13 homers in the minors this year.

Wearing unfashionably high uniform No. 64 and with cousin Randy in the stands, the 6-foot-5, 239-pound outfielder threw out Tomás Nido trying to stretch a third-inning single into a double after a one-hop drive off the right-field wall. Encarnación struck out and grounded out in his first two at-bats, then came to the plate with Alcantara (7-2) trailing 1-0 in the seventh.

Seth Lugo relieved Chris Bassitt (5-5) with the bases loaded. Encarnación got some tips from hitting coach Marcus Thames and got ahead 3-and-1 in the count. He took a called strike and then drove a 92.6 mph fastball 371 feet to the opposite field and over the right field wall.

“Threw a pretty good backdoor sinker, and he just went with it,” Lugo said. “Figured staying away was a safe bet.”

New York, an NL-best 44-24, lost for only the second time in 12 home games. Miami stopped a three-game skid and won for just the second time in 10 games at Citi Field.

Bassitt stretched his scoreless streak to 14 innings before the seventh, when the Marlins loaded the bases on singles by Miguel Rojas and Jacob Stallings followed by Bryan De La Cruz’s one-out walk.

Alcantara, whose 1.72 ERA is second in the major leagues behind San Diego’s Joe Musgrove, allowed six hits in eight innings, struck out eight and walked one. He has pitched seven innings or more while allowing two earned runs or fewer in eight straight starts, the longest such streak since 16 in a row by Seattle’s Félix Hernández in 2014.

Francisco Lindor put the Mets ahead with a run-scoring single in the sixth, his 52nd RBI. Luis Guillorme added an RBI single in the seventh.

Bassitt struck out a season-high nine while allowing three runs and five hits in 6 1/3 innings.
