ST. LOUIS — The Mets haven’t hit much since Opening Day, wasting strong pitching in the process.

Wednesday, it was Freddy Peralta’s fine work, with solid relief behind him, that got forgotten as Masyn Winn’s bloop single in the 11th inning sent the Mets to a 2-1 loss to the Cardinals at Busch Stadium.

The Mets, who lost for the third time in four games, went 0-for-11 with runners in scoring position, getting their only run on a Juan Soto homer. In the three-game series, they went 1-for-29 with runners in scoring position.

A night earlier, the Mets wasted Kodai Senga’s solid work over six innings in a 3-0 loss.

“I still believe in what we have,” Francisco Lindor said. “[David] Stearns and the front office did a good job of putting a good team together, and we have got a good team. … It’s hard to win if you don’t score runs. Overall, I think we are just a couple of pitches away.”

The Mets wasted a bases-loaded opportunity in the 11th inning, with Brett Baty hitting a grounder that resulted in a force out at the plate before Marcus Semien was retired to end the inning. The Mets also left two runners on base in the 10th inning, when Soto was retired for the final out.

“We have just got to get back to what we do well, which is controlling the strike zone, getting good pitches to hit and doing damage,” manager Carlos Mendoza said. “Good hitters that right now, a couple of games, they’re not getting it done.”

The Mets scored only five runs in the three games. They have already played three extra-inning games, including two they split against the Pirates last weekend.

Tobias Myers, in his second inning of relief, induced a double-play grounder from Alec Burleson after intentionally walking Iván Herrera to begin the 11th, with the automatic runner at second. Winn won it with his bloop to right that fell in front of a diving Carson Benge.

“Our pitchers have done a tremendous job,” Lindor said. “We have got to score runs for them.”

Peralta showed improvement from his Opening Day start by allowing one earned run on three hits with seven strikeouts and two walks over 5 ¹/₃ innings in a no-decision. The ace right-hander allowed four earned runs over five innings against the Pirates in his Mets debut last week.

Peralta retired 11 straight following Herrera’s single in the first inning. Nolan Gorman snapped the string by drawing a walk to begin the bottom of the fifth.

The Mets didn’t get their first base runner against Matthew Liberatore until Mark Vientos stroked a two-out double in the fifth. Semien followed with a walk before Francisco Alvarez struck out to end the inning.

Peralta escaped a jam in the fifth by retiring Victor Scott II for the final out after walking Gorman and allowing a single to Thomas Saggese, who had reached second on a wild pitch with one out. Gorman remained at third.

Soto’s first homer of the season produced the game’s initial run. Soto lofted a fly to right that landed just inside the foul pole. Lindor led off the sixth by reaching on Gorman’s fielding error, but was picked off first base. Soto homered three pitches later.

Gorman delivered a two-out RBI single in the sixth to tie it 1-1. The run was charged to Peralta, who departed with runners on first and second with one out. Huascar Brazobán retired Winn before surrendering the game-tying single to Gorman.

Luis Robert Jr. singled leading off the seventh and with two outs Alvarez reached on a catcher’s interference. But pinch hitter Benge struck out against lefty JoJo Romero to leave the go-ahead run at second base.

Jorge Polanco doubled leading off the ninth, but the Mets never pushed across pinch runner Jared Young as Robert, Baty and Semien were retired in succession.

“We have got to make some adjustments, but they are good hitters,” Mendoza said. “And right now, for the last couple of games, they haven’t gotten the job done.”
