BALTIMORE -- Henry Urrutia broke a ninth-inning tie with his first major league home run, and the Baltimore Orioles ended a nine-game losing streak against the New York Mets with a 5-4 victory Wednesday night.

Jonathan Schoop and Adam Jones also homered for the Orioles, who hadn't defeated the Mets since June 18, 2009.

Baltimore rallied from 3-1 and 4-3 deficits before Urrutia led off the ninth with a drive into the seats in left field off Carlos Torres (4-5). That gave the Orioles a split of the two-game series and their fifth win in six games.

Zach Britton (4-0) worked the ninth for Baltimore.

Daniel Murphy and Wilmer Flores both homered and had two RBIs for the first-place Mets, who have lost four of five.

After Schoop made it 3-3 in the sixth with a two-run homer, Flores put New York up 4-3 in the seventh with a solo shot off rookie Mychal Givens.

Jones answered in the bottom half, connecting off Hansel Robles to even the score.

Mets rookie Noah Syndergaard gave up three runs and eight hits in five-plus innings. He had a 3-1 lead in the sixth before yielding a double to Chris Davis and Schoop's home run.

That ruined Syndergaard's bid for his first big league road win. He's 7-1 at home and 0-5 in eight starts on the road.

Orioles starter Ubaldo Jimenez allowed three runs, five hits and four walks in five innings.

After Murphy homered in the top of the first, Syndergaard walked to the mound eager to see if an adjustment in his pregame workout would increase his effectiveness. Because he had given up 10 first-inning runs in 17 starts, the right-hander pushed back his warmup session in the bullpen to lessen the down time before his first pitch.

''We try this out and see if it helps. It can't hurt,'' manager Terry Collins said.

The experiment started poorly. Manny Machado doubled on the first pitch and the Orioles quickly loaded the bases with no outs. Syndergaard then struck out Davis on a 3-2 pitch, and after Schoop bounced into a double play, Syndergaard pumped his fist before heading to the dugout.

New York made it 2-0 in the fourth when Jimenez issued three walks and Flores delivered a two-out RBI single.

After Steve Clevenger hit a run-scoring single in the bottom half, a double by Curtis Granderson and a single by Murphy put the Mets up 3-1 in the fifth.
