New York - Nick Swisher hit a sacrifice fly in the 10th inning and the New York Yankees rallied from a five-run deficit for an 6-5 victory over the Baltimore Orioles Thursday night to sweep the rain-shortened series.

After Joba Chamberlain used his big body to save a run in the eighth by blocking the plate and keeping the Yankees within 5-4, Jorge Posada led off the bottom of the ninth with a tying homer on the first pitch off closer Kevin Gregg.

Michael Gonzalez (0-1) walked Mark Teixeira and gave up a double to Alex Rodriguez to start the 10th. After Robinson Cano lined out, Swisher hit a fly and Teixeira easily beat right fielder Nick Markakis' throw home. Swisher earned the Yankees' first pie in the face of the season for a game-winner.

Mariano Rivera (1-0) gave up a leadoff single in the 10th. But Derrek Lee grounded into a double play and Vladimir Guerrero grounded out.

Chamberlain relieved Bartolo Colon in the eighth inning with runners on first and third. Chamberlain threw a pitch in the dirt that went to the backstop, and the ball took a long bounce off the wall as catcher Russell Martin went to retrieve it.

Martin tossed the ball to Chamberlain, who turned sideways and shielded pinch-runner Felix Pie from reaching the plate. Pie made a standup slide rather than going all the way down and thought he was safe - Orioles manager Buck Showalter came out to argue, but replays clearly showed Chamberlain made the tag in time.

Gregg's meltdown spoiled a solid six-inning effort by Jake Arrieta and handed the Orioles their fourth straight loss after a 6-1 start. Baltimore built its early lead against Phil Hughes, who struggled once again.

Rodriguez, who went 3 for 3, doubled in the fifth for New York's first hit against Arrieta and Cano followed with a double to pull New York to 5-1.

Teixeira hit an RBI double and Rodriguez added a sacrifice fly in the sixth. Martin had a run-scoring grounder off reliever Jason Berken in the seventh to make it a one-run game.

The Yankees' win ended a more than 10-hour day of big league baseball in New York. The Mets were swept by Colorado in a doubleheader at Citi Field that started at 12:20 p.m. and ended just after this game started.

Struggling with low velocity on his fastball, Hughes lasted just 4 1-3 innings after going only two innings against Boston in his last start and four in his first start of the season.

He reached 92 mph twice in the first inning but was throwing consistently in the 88-89 mph range after the second. Manager Joe Girardi said that location was more important that speed. On Markakis' two-run homer in the third, the pitch - an 86 mph cutter - was way off Martin's target.

In the fourth, Luke Scott doubled and scored on Mark Reynolds' drive that Curtis Granderson caught leaping into the wall in right-center for a 3-0 lead.

Swisher crashed into the wall in right field catching a flyball in the fourth, one batter before Markakis lined an RBI double to right, ending Hughes' night.

• Kevin Millwood, who signed a minor league deal with New York on March 25, is scheduled to pitch for Double-A Trenton on Sunday.
