Noah Syndergaard put aside trade talk to turn an eighth-inning lead over to his relievers, and the Mets rebounded from another bullpen meltdown when Jeff McNeil and Michael Conforto hit consecutive home runs in the 11th.
In their first game since trading for All-Star pitcher Marcus Stroman, the Mets extended a winning streak to five games for the first time since April 2018. After falling to 40-51, the Mets have won 11 of their last 15 games to move within the outer edge of the NL wild-card race.
Given a 2-0 lead, Syndergaard gave up an unearned run in the sixth when third baseman Todd Frazier bobbled Jose Abreu's two-out grounder, allowing Yolmer Sanchez to score. The 26-year-old right-hander allowed five hits in 7 1/3 innings.
Syndergaard, not eligible for free agency until after the 2021 season, tweeted a GIF on Sunday of an actor who played Thor - his nickname - in a movie with the words ''I HAVE NO IDEA WHAT'S GOING ON'' superimposed.
Seth Lugo relieved with the bases loaded and got Abreu to ground in to an inning-ending double play.
Edwin Diaz then blew a save for the fifth time in 28 chances when he walked Ryan Goins leading off the ninth, threw a wild pitch as Eloy Jimenez struck out, hit James McCann with a pitch, threw another wild pitch, then allowed a sacrifice fly to Tim Anderson.
Amed Rosario singled off Jose Ruiz (1-2) leading off the 11th for his fourth hit, and McNeil greeted Josh Osich with his 11th home run - his first this year off a left-hander, The drive barely cleared the fence in right-center.
Conforto homered two pitches later, giving him home runs in three straight games.
Robert Gsellman (2-2) pitched perfect two innings. The Mets had lost their previous five extra-inning games since beating Detroit on May 25.
New York built its lead on RBI groundouts by Tomas Nido in the second and Robinson Cano in the fourth.
Chicago starter Reynaldo Lopez allowed two runs and six hits in 5 1/3 innings. The White Sox have lost six of seven. They were 41-42 before play on July 4 but are 5-16 since.
Anderson was activated from the 10-day IL (sprained right ankle) and was 0 for 3 in his first big league game since June 25.
Yoan Moncada came out after the first inning with right hamstring tightness.
Jacob deGrom (6-7, 2.86) is scheduled to start Wednesday against White Sox RHP Lucas Giolito (11-5). DeGrom has a 17-inning scoreless streak. Giolito is 0-3 with a 7.06 ERA in his last four starts.
