Starling Marte said he didn’t regret a thing.

After the Mets’ 3-2 loss to the Brewers on Thursday, in which Marte struck out with the bases loaded to end the game, many fans were shocked that the veteran swung and struck out on three straight pitches.

Despite a woman in the seats behind home plate who went viral for yelling to Marte “don’t swing at everything” during his at-bat, the outfielder already appeared to have had his mind made up once he stepped up to the plate.

“My mentality was to see the ball and hit the ball there,” said Marte, who was not in the starting lineup for Friday’s game at Citi Field against the Giants. “Obviously, fans can say what they want to say. But at the end of the day, I’m the one that’s there standing at the plate, so I have to try and have that success myself. We’ve been doing this since we were kids, and yeah, we have that experience and when you’re there, you kind of have to see it for yourself.”

As experienced as the 12-year veteran is, he didn’t look it Thursday, swinging at three consecutive changeups from Brewers pitcher Devin Williams to end the Mets’ night and continue their precipitous free fall down the National League East standings.

Regardless, Marte said he had no regrets and wouldn’t have changed a thing.

“No, I wouldn’t have done anything different,” he said. “He missed on a pitch that I ended up missing on as well, that I didn’t execute on. And then he came back and executed his best pitch, and that’s where he got me out. But I wouldn’t have done anything different.”

Marte had started the previous 15 contests entering Friday, batting .234 with one home run, two doubles, six RBIs, nine runs scored and three stolen bases during that stretch.

But during the Mets’ four-game series against Milwaukee that wrapped Thursday, he went 3-for-17 (.177) without driving in a run.

For Mets manager Buck Showalter, the decision to leave the two-time All-Star out of the lineup against the Giants on Friday was an easy one.

“Felt he needed a day, and I want to get Mark [Canha] in there when I can,” Showalter said.
