PORT ST. LUCIE, Fla. — Jacob deGrom was dominant Thursday in his second start of spring training. The righty threw four shutout innings against the Tigers in the Mets’ 5-5 tie at First Data Field.

DeGrom, who is coming back from elbow surgery, allowed two hits and struck out four. He has not allowed a run in six innings.

At this time last year, deGrom was facing questions about reduced velocity as he dealt with a lat strain. He made 24 starts in the regular season before his elbow woes became too much to handle.

“I feel good,” deGrom said. “And that was the main thing, to be healthy . . . I think that I definitely do feel stronger this year.”

Wheeler’s up

Zack Wheeler will make his first start since 2014 Tommy John surgery on Friday against the Braves in Lake Buena Vista.

Wheeler declined an interview request, but manager Ter ry Collins can only imagine how the 26-year-old is feeling.

“I’m glad to get him back out there,” Collins said. “He’ll do fine if he just keeps himself under control and doesn’t try to overthrow . . . Just hoping that he doesn’t go out there and try to do too much his first time out there in two years.”

No Walker talks

The contract extension talks between the Mets and second baseman Neil Walker that broke down last month have not been revived, Walker said. If no extension is reached, he will be a free agent after the season.

“It’s been tabled,” Walker said. “We had some talks and nothing ever came to fruition.”

Extra bases
