Marcus Stroman’s first three starts as a Met were underwhelming. His fourth was worse — he was forced to leave because of injury.

The right-hander departed Wednesday night’s game at Citi Field against the Indians after the fourth inning with left hamstring tightness, leaving heavy lifting for the bullpen.

In this magic carpet ride of a run, however, it didn’t matter. The bullpen allowed just two runs over six innings, and the Mets rallied for two runs in the bottom of the 10th to prevail, 4-3, and improve to a major league best 26-10 since the All-Star break.

Even better, manager Mickey Callaway said Stroman, who underwent an MRI exam, was expected to be fine.

“We’re not concerned at this point,” Callaway said. “We’ll have to check on him in the morning, but it’s not a concern at this point. It’s tightness.”

Stroman felt the hamstring tighten up as he went to cover first base for the final out of the fourth inning. He allowed one run on five hits while he was in there, standing runners in three of his four innings. He has a 4.58 ERA as a Met, giving up 25 hits in 19 ²/₃ innings since he was acquired from the Blue Jays on July 28 for highly regarded pitching prospects Anthony Kay and Simeon Woods-Richardson.

As in his previous three starts, Stroman managed to limit the damage. His best work came in the third inning, after Carlos Santana doubled to right field to send Francisco Lindor, who had singled, to third. Stroman retired Yasiel Puig on a run-scoring groundout, then got Jose Ramirez to fly out.

Losing Stroman would be a significant blow to the Mets, who don’t have much starting pitching depth.

The likely replacement for Stroman would be Walker Lockett, who has filled in at times when the Mets need a spot starter, but has pitched to a 7.79 ERA.

Fortunately for the Mets, it doesn’t seem as if Stroman will be out long, if at all.
