BALTIMORE - Michael Pineda took the mound Friday night for the first time in 11 days, the lengthy time between starts giving the young pitcher's right arm some extra rest.

"The concern [after] a long layoff is the command," manager Joe Girardi said beforehand. "Hopefully he comes out and is locked in."

Pretty much the exact opposite scenario played out in a sloppy 11-3 loss to the Orioles in front of 33,203 at Camden Yards.

"It wasn't pretty to watch, it wasn't real pretty to be a part of," Brett Gardner said, speaking of the night overall, one in which the Yankees didn't resembld the first-place team they are at the plate, on the mound or in the field. "Hopefully we got it all out of our system."

Pineda (7-3, 3.74) walked the first batter he faced, the beginning of a short night that seemed longer.

The 26-year-old righthander lasted a season-low 41/3 innings, allowing six runs -- five earned -- nine hits and two walks. Pineda, who struck out two after punching out 16 Orioles in his last start against them, May 10 at the Stadium, threw 80 pitches, 50 for strikes.

"It could be," Girardi said of the layoff impacting Pineda. "This was not something we really wanted to do but you're talking about a guy that just hasn't thrown a lot of innings."

Pineda's season-high in innings is the 171 he threw in 2011, with shoulder surgery costing him 2012 and 2013 and more shoulder trouble limiting him to 761/3 innings last year.

"We don't want to blow him out by July," Girardi said.

Pineda downplayed the time off and said his biggest issues Friday night were a slider lacking its usual bite and general location difficulties. He also received little defensive help.

Third baseman Chase Headley's nightmare season in the field continued with his 14th error, a botched ball in a four-run third -- which made it 5-1 -- that had the added indignity of drilling him in the groin. Headley left two innings later because of lingering nausea.

"Most of the time you get over it pretty quickly but for whatever reason it was not going away," said Headley, who hopes to play Saturday night.

There was rookie centerfielder Mason Williams, called up Thursday, badly misreading a ball in the fourth inning, which led to a run. This, after hitting a two-run homer in the top half that pulled the Yankees (33-27) within 5-3.

Alex Rodriguez had two hits, giving him 2,994.

With Pineda long gone, Mark Teixeira had his 109-game streak without an error end in the sixth, when he threw high to second, and into leftfield, in an attempt to get the lead runner, leading to three runs in a four-run frame that made it 10-3.

And then there was Caleb Joseph's fly ball in the seventh that landed between the pursuing Gardner from center and Carlos Beltran from right. Both suddenly stopped, a miscommunication leading to yet another run that made it 11-3.

"Neither of us called it," Gardner said. "As centerfielder I have to call him off."

Orioles righthander Ubaldo Jimenez (4-3, 3.19) was far from sharp, though he got out of a bases-loaded, none-out jam in the first without allowing a run. Jimenez allowed three runs and six hits in five innings.

"It's hard to put our finger on," Girardi said of the defensive lapses. "These guys have a history of playing good defense and they're just not doing it."
