The Mets finally quieted Shohei Ohtani’s bat in his final New York appearance before free agency this winter, and two late rallies helped them avoid a weekend sweep by the Angels.

David Peterson tossed seven innings of one-run ball in his longest start of the season, and Rafael Ortega’s bases-loaded single in the ninth sent the Mets to a 3-2 walk-off win at Citi Field to halt their four-game losing skid.

Despite a UCL tear in his right elbow that will prevent him from pitching again this season, Ohtani had been 3-for-5 (all extra-base hits) with five walks over the first two games of the series.

But the two-way superstar went hitless on Sunday in four trips with two strikeouts.

Peterson, who entered with a 5.59 ERA, nursed a 1-0 lead into the seventh before the Angels tied it on an infield out.

The lefty struck out eight and walked three over seven (104 pitches), but Drew Smith promptly was tagged for a leadoff shot to right-center by Luis Rengifo in the eighth for a 2-1 Angels lead.

Pete Alonso tied it again with an RBI double to left-center against lefty reliever Matt Moore in the bottom half, before Ortega ripped a game-winning single to right with the bases loaded in the ninth against righty Reynaldo Lopez.
