NEW YORK -- Scuffling throughout the second half of April, and in particular on the road, the Giants made sure not to leave Flushing without a parting gift. Madison Bumgarner outpitched Noah Syndergaard on Sunday, Hunter Pence clubbed a two-run homer and the Giants snapped the Mets' eight-game winning streak with a 6-1 victory of their own at Citi Field.
Hardly dominant, Bumgarner was plenty good enough against a Mets team resting some of its top left-handed bats on a rainy afternoon. The Giants lefty stranded runners in scoring position in the first, third and sixth innings, bedeviling a Mets lineup stocked with seven right-handed batters.
Said Bumgarner, who has complained about his balky pitching mechanics, "It didn't feel like I was 100 percent where I would like to be, but it's really close."
Syndergaard was unable to navigate trouble with quite the same success. His issues curbing the running game resurfaced via a troika of Giants stolen bases, though the biggest blow against Syndergaard was Pence's two-run, opposite-field home run in the fourth.
"It was just kind of a disappointing start," said Syndergaard, who has given up seven runs over his last two outings after allowing a total of two in his first three. "My last two starts, I haven't felt very comfortable on the mound."
MOMENTS THAT MATTERED Get moving: San Francisco's three-run outburst in the fourth inning was made possible by putting Buster Posey in motion on a 3-2 pitch to Brandon Belt. Posey pulled in safely at second base, preventing an inning-ending double play and enabling Matt Duffy to score from third. Pence followed with his opposite-field home run to right. The Giants remained running-conscious all afternoon, stealing a season-high four bases.
Giants manager Bruce Bochy said his thieves ran on their own. But Posey's dash for second base was ordered.
"That's Boch. That's not me," Posey said. "He gets the credit for that one."
Rally cut short: A Juan Lagares leadoff double in the seventh breathed life into the Citi Field crowd, which grew even louder when David Wright followed with an RBI single. But Bochy's mix-and-match game worked to perfection when Michael Conforto flied out against lefty Javier Lopez, and Yoenis Cespedes hit into an inning-ending double play against right-hander Cory Gearrin. An inning later, the Mets stranded two more runners versus lefty Josh Osich.
"We just didn't get the timely hits tonight," Mets catcher Kevin Plawecki said. "That's really all there is to it."
He's no Bum: Bumgarner saved his best for last. With the bases loaded and two outs in the sixth inning, he struck out pinch-hitter Asdrubal Cabrera on three pitches. Bumgarner concluded the confrontation -- and his outing -- with a 91 mph fastball that Cabrera took as it shaved the inside corner. Bumgarner has now thrown 18 consecutive scoreless innings at Citi Field, the longest scoreless streak by an opposing starter in the ballpark's eight-year history.
Informed of the statistics, Bumgarner reacted as he typically does. He refused to sound impressed with himself.
"I hadn't thought about it," he said. "It is a fun place to pitch. You're in New York and pitching against a good team. I don't really know. I just try to be the same guy every time I go out there."
"He's just kind of funky," Plawecki said of Bumgarner. "[His delivery] isn't even really three-quarters. It's somewhat not sidearm, either. It's kind of hard to explain. But he changes speeds very well and he locates his pitches."
"I was about 20 minutes late in my pregame routine. So it's a good thing I'm not a big routine guy." -- Bumgarner, referring to the morning buzz about the likelihood of a rain delay or postponement
SOUND SMART WITH YOUR FRIENDS
Syndergaard's weakness against the running game was on full display against the Giants. Stolen bases from Brandon Crawford (once) and Duffy (twice) gave opponents a league-best 12 in 13 tries off Syndergaard this season, regardless of who is catching. Basestealers enjoyed a 94 percent success rate off Syndergaard last season.
UPON FURTHER REVIEW
The Giants challenged a second-inning ruling involving Pence, who was called out at first base after he hit a slow bouncer toward third base and tried to beat Wright's one-hop throw. After a 59-second replay review, it was announced that the call on the field stands.
Five and a half innings later, a crew-chief review went in the Giants' favor. Umpires initially called Lagares' leadoff hit down the right-field line a triple, but a three-minute, one-second review resulted in a new ruling of fan interference, forcing Lagares to settle for a double.
WHAT'S NEXT Giants: The second half of San Francisco's two-city, six-game trip opens Monday at 4:10 p.m. PT in Cincinnati, which is no longer a place for the Giants to fear. They lost eight of nine games at Great American Ball Park from 2011-13 but finished 5-2 there in the last two seasons.
Mets: The Mets' stretch of 17 games in 17 days continues Monday with a 7:10 p.m. ET match at Citi Field against the Braves. Bartolo Colon will take his third crack at career win No. 220, which would move him into second place all-time among Dominican-born pitchers.
