Zack Wheeler could be making his last start as a New York Met later this week.

A team source told Yahoo Sports that chances are “pretty high” Wheeler won’t be a Met on August 1.

“It’s just where we’re at,” the source said. “If we played better in San Francisco [over the weekend], it might have changed everything.”

The Mets entered Tuesday in fourth place in the NL East with an underwhelming 45-54 record. They currently sit 14 games behind division-leading Atlanta.

Wheeler hasn’t started since July 7 due to a right shoulder impingement. But the 29-year-old righty, who will be a free agent at the end of the season, is expected to return on Friday night against the Pittsburgh Pirates at Citi Field.

“I mean, last year was the same way,” Wheeler said of his name being mentioned in talks with the July 31 trade deadline quickly approaching. “You try to just go out there and get a win and concentrate on that. I’m here now, so I’m not worried about that.”
