NEW YORK -- Eric Young sparked New York in the field and at the plate on Tuesday night and Marlon Byrd's two-run homer capped a three-run sixth inning as the Mets beat the Atlanta Braves 5-3 in front of 25,863 at Citi Field.
The Mets (58-66) won their second in a row and the Braves (76-49) lost for just the fourth time in their last 23 games.
Young scored two runs for the Mets and Ike Davis was 2-for-4 with an RBI single in the first and a solo homer in the eighth.
Rookie right-hander Zack Wheeler emerged from a tumultuous seventh inning with his second career home win. Wheeler (6-2) allowed three runs -- all of which scored after he left the game -- six hits and three walks while striking out five in 6 2/3 innings.
Andrelton Simmons had a three-run double in the seventh for the Braves, who had at least one hit in seven innings but stranded seven runners. Freddie Freeman finished with two singles.
Braves starter Brandon Beachy (2-1) took the loss after allowing all four runs (three earned), five hits and no walks with four strikeouts in six innings.
Young opened the bottom of the first by reaching on a throwing error by Simmons and scoring the Mets' first run on Davis' two-out single.
With the Mets nursing a 1-0 lead, Young ended the top of the sixth by making a sensational diving catch to rob Brian McCann of a hit.
Young led off the Mets' sixth with a bunt single. He went to second on Daniel Murphy's single before both players took off on a double-steal. McCann's throw to second sailed into center field and Young scampered home.
Three pitches later, Byrd homered to left to extend the Mets' lead to 4-0. It was the career-high 21st homer of the season for Byrd, who hit just one homer in 153 at-bats last year before making the Mets this spring as a non-roster invitee.
Byrd's homer proved especially vital when the Braves scored three runs in the seventh. Wheeler was one out from completing seven scoreless innings when the Braves loaded the bases via a single and two walks. Simmons greeted Carlos Torres with a three-run double to left before Scott Rice escaped the jam by retiring Freeman on a fly out to left.
Gonzalez Germen worked around a two-out single in the eighth and LaTroy Hawkins picked up his fifth save with a perfect ninth.
The Mets took a 1-0 lead in the first when Young led off by reaching on Simmons' throwing error. Young stole second, went to third on Byrd's groundout and scored on Davis' two-out single to right.
The Braves had a hit in each of the first five innings against Wheeler, but the right-hander continually wriggled out of jams. He escaped a first-and-third situation in the third by getting Evan Gattis to pop out to catcher Travis d'Arnaud.
NOTES: The Mets got some downbeat, if expected, news regarding two starting pitchers. RHP Jeremy Hefner, who is on the disabled list with a partially torn MCL in his right elbow, was told during a visit with Mets medical director David Altcheck that he'll likely require Tommy John surgery. RHP Jenrry Mejia, who has been pitching with bone chips in his right elbow and left his start on Saturday night with pain in the elbow, will undergo surgery to remove the chips and other debris within the next week to 10 days. ... The Mets signed RHPs Mitch Talbot and Daryl Thompson and assigned them to Triple-A Las Vegas. ... Braves OF Justin Upton was scratched just 15 minutes before first pitch and replaced by Gattis. ... Braves manager Fredi Gonzalez said the team will activate LHP Paul Maholm from the disabled list on Thursday and Maholm will start against the St. Louis Cardinals. Maholm has been out since July 21 with a left wrist contusion. ... Braves 2B Dan Uggla, who was placed on the 15-day disabled list on Aug. 13 and underwent LASIK surgery three days later, took batting practice before the game.
