Lucas Duda's career-high 16th home run, a solo shot to deep center field off Milwaukee starter Matt Garza (7-7) in the seventh, was the lone Mets highlight. Wilmer Flores, starting for Ruben Tejada, had the first hit, an infield single in the third.
Gee (4-3) looked to bounce back from his shortest start of the season but ended up matching it when the long ball bit him for the second straight game.
In his previous start at San Diego on July 19, Gee surrendered home runs to Will Venable and Yasmani Grandal. The Padres rocked him for four runs on five hits in five innings. He struck out eight and didn’t issue a walk, but it just wasn’t enough to prevent the loss.
The right-handed-batting Lucroy started the pummeling when he lined an 89 mph cutter over the left-field wall in the bottom half of the first inning.
Gee then gave up four runs in the second, highlighted by Jean Segura's two-run triple. Carlos Gomez and Lucroy each tacked on run-scoring singles. Duda ranged far to his right and made a diving lunge at Lucroy’s roller, but the ball just scooted under the first baseman’s glove.
Davis’ RBI double in the third made it 6-0 and prompted activity in the Mets bullpen, but Gee retired the next two batters to escape further harm. He pitched two clean innings in the fourth and fifth, but his 11th start this season was over when Eric Young Jr. pinch-hit for him in the top of the sixth. Gee threw 91 pitches, 60 for strikes, gave up six hits, walked two and struck out six in five innings.
Davis made it 7-0 in the sixth when he launched the first pitch from Daisuke Matsuzaka into the Brewers bullpen in left. Braun teed off in the seventh with Gomez aboard to ensure the Brewers’ fourth straight win.
In the seventh, manager Terry Collins asked for a review of a close play at first on a grounder to second by David Wright. After scrutinizing the video for 2 minutes, 26 seconds, the out call was confirmed.
Ouch: Daisuke Matsuzaka appeared to be injured after completing the seventh inning. He met with staff in the dugout.
What’s next: Zack Wheeler (5-8, 3.78 ERA) faces fellow right-hander Yovani Gallardo (5-5, 3.79) on Friday at 8:10 p.m. in the second of the four-game series. Wheeler won his only career start against the Brewers on July 5 last season at Miller Park. Gallardo was perfect in two starts against the Mets last season but has not faced them in 2014.
