Wolf made five starts in the first month of the season, allowing less than four runs in just two of those outings, including a 5-4 victory over New York on April 18.
Wolf improved to 6-4 with a 3.23 ERA in 20 career starts against New York, allowing three runs over a season-high eight innings while striking out five and walking none.
He’s been far less effective against the rest of the league, including dreadful performances in his last two outings.
In losses at Atlanta on April 23 and to Florida on Friday, Wolf allowed 10 runs and 15 hits in nine innings.
“I’m just embarrassing myself, out there, that’s it,” Wolf said after Friday’s 6-4 defeat to the Marlins in which he allowed three homers. “I’m not pitching like a major-league pitcher right now.
“I’m letting my teammates down, and that’s hard. I need to do a better job.”
Cliff Floyd was the lone bright spot for the Mets, connecting for his seventh home run to extend his hitting streak to a career-high 19 games— longest in the majors this year.
The Mets have lost three of five.
