Gee (11-9) cruised after he was given a 5-0 lead in the third. The right-hander allowed one run on four hits in seven innings.
Freddie Freeman homered off Mets reliever Vic Black with two outs in the eighth.
The Mets had 12 hits, including 11 in only 4 1-3 innings against Kameron Loe (0-2), who made his first start in the majors since 2007. He filled in for Julio Teheran, who was given a rest - a possible sign of things to come this month as the Braves move closer to the postseason.
At least two Mets hitters reached base in each of Loe's innings.
LaTroy Hawkins gave up a double to Elliot Johnson to lead off the ninth. Dan Uggla and pinch-hitter Andrelton Simmons popped up and Hawkins earned his seventh save when pinch-hitter Chris Johnson struck out.
Loe, 33-43 in nine seasons with Texas, Milwaukee, Seattle, the Cubs and Braves, had pitched only in relief since making his last start with Texas in 2007. He was recalled from Triple-A Gwinnett on Monday and struggled in every inning against the Mets.
With one out in the first, Daniel Murphy tripled and Brown hit a homer that landed about halfway up the lower level of seats in left field.
Duda's homer was the start of the Mets' three-run third inning.
The low point for Atlanta in the inning came when center fielder B.J. Upton and left fielder Evan Gattis watched Gee's fly ball fall to the ground in the gap. The ball dropped closer to Upton, who stopped running and then looked at Gattis. Juan Lagares scored on the play.
Braves fans cheered when manager Fredi Gonzalez came to the mound to remove Loe in the fifth after the right-hander walked Gee.
Gonzalez rested Simmons, third baseman Chris Johnson and catcher Brian McCann.
The Braves had only one hit, a single by Paul Janish in the second, before scoring once in the fifth. Upton's sacrifice fly drove in Uggla, who singled and moved to third on Paul Janish's second single.
