NEW YORK -- Chad Kuhl was looking to bounce back Tuesday night, after recording his shortest outing of the season on Thursday, lasting just two innings in a loss to the D-backs. But it was not his night. Though the offense eventually came alive for the Pirates, the Mets outlasted Pittsburgh to post a 4-3 walk-off win in the 10th inning at Citi Field.
The Pirates have lost five of the last six games that Kuhl has started.
The teams traded offensive blows through nine innings before Wilmer Flores hit a game-winning single up the left-field line in the bottom of the 10th off reliever Steven Brault to give the Mets the win.
In the first inning, Kuhl gave up a hit, a walk and threw two wild pitches that advanced Mets baserunners into scoring position. Flores then knocked in two runs with a single to put the Mets up, 2-0. The Pirates pitchers threw four wild pitches Tuesday -- three by Kuhl -- falling one shy of the franchise record.
Mets left-hander Steven Matz held the Pirates hitless until David Freese, Elias Diaz, Jose Osuna and Gregory Polanco had four straight hits in the fifth to get the Pirates on the board and tie the game at 2.

Kuhl seemed to settle in, only giving up one hit after the first inning. But the medical staff had other thoughts. In the fourth inning, Kuhl was looked at on the mound by trainers but finished the inning. He was removed from the game after the fourth with right forearm discomfort and was treated by medical staff at Citi Field.
"I thought he battled after giving up the two runs," Pirates manager Clint Hurdle said. "Then he settled in, was making pitches. He put up three zeros, and at one time, we had the lead."
Polanco's solo home run gave the Pirates that lead in the seventh inning, only for Mets outfielder Michael Conforto to respond with a solo shot of his own off reliever Edgar Santana in the bottom of the inning, setting the stage for Flores' 10th-inning heroics.

SOUND SMART
Polanco's homer in the seventh inning was also his 500th career hit. He has now homered in back-to-back games, the fourth time he has accomplished that feat.
YOU GOTTA SEE THIS
In the eighth inning, the benches and bullpens cleared after Josh Harrison slid into second base, breaking up a double play, and Mets reliever Jeurys Familia told him to "play the game the right way."
Harrison, being a middle infielder, was not overly concerned with the play because he felt that he was indeed playing the game the right way, and he talked to Mets second baseman Asdrubal Cabrera after the play, and they were good.

MITEL REPLAY OF THE DAY
Two innings before his homer, Polanco put his athleticism on display in right field, racing in to make a dramatic diving catch on a Todd Frazier pop that was originally ruled a hit. Frazier thought the ball had been trapped and that he had reached with a two-out, bases-empty knock. After a brief review initiated by a challenge from Hurdle, however, the call was overturned and ruled an inning-ending grab.

HE SAID IT
"He's a good man. He's a good baseball man, and I've developed a little bit of a relationship with him, so my thoughts are definitely out there for him and will continue to be with him." -- Hurdle, on Mets general manager Sandy Alderson's leave of absence
Tuesday, Alderson announced he will be taking an immediate leave of absence to address a personal health concern. Alderson will undergo surgery later this year to treat his recurrence of cancer.
UP NEXT
On Wednesday, Ivan Nova will make his 15th start of the season. Nova pitched eight scoreless innings against the D-backs in his last start, giving up three hits and striking out eight. Since returning from the disabled list with a sprained right ring finger, he is 2-0 with a 0.92 ERA through three games. Nova has made four career appearances against the Mets, but all have come with the Yankees. He will take the mound at 7:10 p.m. ET against Mets right-hander Zack Wheeler.
