Mets defeat Dodgers, 2-1, by scoring a run off Kenley Jansen

KEY MOMENT: With the game tied, 1-1, closer Kenley Jansen gave up a double to Lucas Duda to start the ninth inning. Jansen then failed to field a weak comebacker by Wilmer Flores, resulting in an infield hit that advanced Duda to third base. Duda scored on a sacrifice fly by Kevin Plawecki to break the stalemate.

AT THE PLATE: Adrian Gonzalez increased his season home run total to 14, as he took Noah Syndergaard deep to center in the second inning to move the Dodgers in front, 1-0. The run was the only one the Dodgers scored against Syndergaard over six innings, as the hard-throwing Mets rookie limited them to two hits and two walks. The Dodgers finished the game with three hits.

ON THE MOUND: Clayton Kershaw pitched seven innings for the third consecutive start but, again, had nothing to show for it. Kershaw limited the Mets to one run and five hits, with two walks. That was enough for him to avoid a fourth consecutive defeat, but it wasn’t enough to earn him his first victory since June 6.

EXTRA BASES: Manager Don Mattingly said he spoke to Brandon League, who was designated for assignment Thursday. “He seemed to be in pretty good spirits,” Mattingly said. League, 2-3 with a 2.57 earned-run average in 2014, had spent the entire season on the disabled list with shoulder problems. He pitched in 10 minor league games as part of a rehabilitation assignment and gave up only one earned run, but Mattingly said the Dodgers didn’t consider him to be one of their seven best relievers. “We have some young guys throwing the ball well out of the bullpen for us,” Mattingly said. The Dodgers remain obligated to pay League what remains of his $7.5-million salary. … Veteran pitcher Trevor Cahill was signed to a minor league contract and is building up his arm strength at the team’s spring-training facility in Arizona. Cahill was released last month by the Atlanta Braves after posting a 7.52 ERA in 15 games, including three starts.

UP NEXT: Zack Greinke (6-2, 1.58 ERA) will face the New York Mets and Matt Harvey (7-5, 2.99) at Dodger Stadium on Saturday at 4 p.m. TV: Channel 11. Radio: 570, 1020.
