BALTIMORE - So much for momentum. And so much for the postseason, probably.
Truthfully, though, that ship sailed long ago.
Anyone who thought Thursday's stunning walk-off victory over the Rays would be the start of some kind of September surge simply hasn't been paying attention to the Yankees this season.
Coming off one of their most stirring wins of the year, they suffered a soul-crushing 2-1 loss to the Orioles Friday in the first game of a day-night doubleheader, losing on Jimmy Paredes' two-out, two-run double off Adam Warren in the 11th inning.
The loss -- which had looked like a potential 1-0 win when Chris Young homered off Brad Brach in the top of the 11th -- was another step toward a second straight dark October.
The Yankees (75-71) took an outright leap in that direction a few hours later, collecting four hits in a 5-0 loss in the nightcap.
"It's hard to win when you only score one run in  innings," Joe Girardi said. The Yankees have been shut out three times in eight games and four times in 13. They fell 12½ games behind the AL East-leading Orioles and are five games behind the Royals and Mariners in the race for the second wild card.
"We have to go on a run, that's the only way to put it," Jacoby Ellsbury said. "We still want to make it interesting. We have to get hot and play very good baseball, but there's still a chance and that's what we have to hold out for."
Girardi lamented his team's close losses of late. "We're probably three or four hits from winning eight out of our last 10, and if you get those hits and three or four pitches as well, it's different, it makes a big difference," he said. "We need to win a lot. But we're capable of doing it."
The Yankees' best chance at a win came in the first game. The teams traded zeros until the 11th as both starters and both bullpens shined. The Yankees' Brandon McCarthy allowed four hits and no walks with six strikeouts in seven innings and the Orioles' Kevin Gausman gave up seven hits and two walks in seven innings, striking out seven.
After McCarthy left, Dellin Betances and David Robertson combined to throw three scoreless innings, with Betances pitching out of a first-and-third, none-out jam in the eighth and Robertson escaping a bases-loaded, two-out situation in the ninth. Warren was called on to close but could not make Young's third key homer in as many games hold up.
"I've been in those situations before, so I don't feel the situation got to me," said Warren, who has two saves this year. "I just think I was a little amped up . . . I rushed a little bit."
The rally started with a leadoff walk to Nelson Cruz, continued with a hit batsman and another walk, and ended when former Yankees farmhand Paredes lined a first-pitch changeup into the rightfield corner.
"It's an unfortunate ending," McCarthy said. "It's tough and it's a quiet clubhouse right now, and it should be."
Making his first career start in Game 2, Yankees rookie righthander Bryan Mitchell allowed two runs and six hits in five innings and Orioles righthander Bud Norris (13-8) allowed three hits in seven innings.
David Phelps, on the DL since Aug. 4 with elbow inflammation, walked the bases loaded in the seventh before giving up Delmon Young's two-out, two-run single. Alejandro De Aza had two RBI triples for Baltimore.
Notes & quotes: Derek Jeter, who was hit in the left elbow by a 94-mph fastball Thursday night, did not play in the first game but started the second game at shortstop and went 0-for-4 . . . Chase Headley did not suffer any broken bones after getting hit in the jaw by Jake McGee's 96-mph fastball Thursday night. He joined the team before the second game after seeing a neurologist earlier in the day in New York. "I'm sore,'' he said, "but it could have been much worse."
