ATLANTA -- The Mets had a long time to stew over their crushing 4-3 walk-off loss to the Braves in Game 1 of their split doubleheader at SunTrust Park on Monday, with a nearly three-hour rain delay pushing back the start of the nightcap to 10:05 p.m ET.
The frustration continued through the first six innings of a back-and-forth nightcap, but the Mets broke through against the Braves' bullpen in a three-run seventh that enabled them to end their four-game losing streak with an 8-5 win in the early hours of Tuesday morning.
"It was big because you had a little bit of both emotions," Mets manager Mickey Callaway said. "You get up and you go down, and they never stop fighting. I think they really came out with some energy and scored early, which was huge in this game, and you gotta give them credit. This is a tough day, long day, and they did the job."
With the bases loaded and two outs in a 5-5 game in the seventh, Luis Guillorme delivered an opposite-field, two-run single to left off Braves lefty A.J. Minter. Amed Rosario extended their lead to 8-5 with an RBI single off righty Lucas Sims. Rosario went 2-for-5 with a career-high three RBIs.
Guillorme made progress at the plate, going 4-for-9 with three RBIs in the doubleheader to raise his average to .267.
"I've been feeling a little better the past few days," Guillorme said. "A little more careful with the pitches I swing at, and everything's more compact down there. So I've been feeling pretty good lately."
The Mets got major contributions from catcher Kevin Plawecki and right-hander Hansel Robles, both of whom were activated from the disabled list prior to Game 1.
Plawecki, who had been on the DL since April 13 with a hairline fracture of his left hand, went 3-for-4 with two runs and an RBI. Robles, who had been on the DL with a right knee sprain since May 9, threw three scoreless innings, giving up just two hits and striking out three.
Robles settled things down in relief of P.J. Conlon, who got the start in a planned bullpen game. The lefty gave up four runs on eight hits and couldn't record an out in the bottom of the third as the Braves plated three runs to take a 4-3 lead.
"He shut down the top-middle of [the Braves'] order, which is very hard to do," Callaway said of Robles. "Their first five hitters are obviously performing unbelievably. They've been doing a really good job, and he went right through them."
Mets closer Jeurys Familia pitched perfect eighth and ninth innings with three strikeouts to earn his 16th save of the season.

The Braves had the tying run in scoring position when Johan Camargo doubled with one out to left-center in the bottom of the second. After Conlon struck out Dansby Swanson, Brandon McCarthy hit a sharp single that center fielder Michael Conforto fielded and fired home to cut down Camargo.
In just his second Major League appearance, Conlon became the first Mets starter to give up eight or more hits through two or fewer innings since Matt Harvey did so against the Astros in a doubleheader on Sept. 2 last season. In his first two big league appearances, Conlon has given up seven earned runs in 5 2/3 innings (11.12 ERA).
