NEW YORK - Jason Hammel had been marvelous this season. There was a near no-hitter in one game, seven innings of shutout ball in another. In all, he'd allowed just five earned runs in 26 innings.

On Monday, he allowed two more, but they were enough to beat him. Hammel allowed a two-run home run to Eric Chavez in the second inning as the Baltimore Orioles lost to the New York Yankees 2-1 before 36,890 at Yankee Stadium.

The Orioles (14-9) managed just four singles, and scratched out a run in the second. They mixed in some aggressive baserunning, but it didn't always work.

Adam Jones was out trying to steal second with two outs in the fourth. Nick Markakis tagged from first on a long fly ball by Jones in the seventh, but was out trying to score on a short wild pitch by Hiroki Kuroda.

"I was just looking to score, tie the game. I thought I had a good jump," Markakis said. "The ball didn't go as far as I wanted [it] to. Nine times out of 10, I'm going to try it."

That was the Orioles' last, best opportunity against the Yankees (13-9). They're 0-4 when playing the Yankees, and 14-5 against everybody else.

"They are the Yankees. They are always good," Chris Davis said.

"I don't think it's anything that we have a mental block or anything like that against them. We've played good, we just haven't capitalized on the opportunities to score runs. You are not going to beat a lot of teams scoring one run, even as well as we've been pitching. You are still not going to do it. We've got to put more runs on the board."

The Orioles scored just one run, and it was on Davis' sacrifice fly in the second inning. New York got its two runs off Hammel (3-1) on the home run by Chavez.

Mark Teixeira led off with a single down the first base line that manager Buck Showalter thought was foul.

He argued with first base umpire Bob Davidson, and two batters after the losing argument, Hammel was down 2-1.

"I'm not going to dwell on that. We had plenty of opportunities to make that not matter," Showalter said.

Hammel's stuff was good. He allowed two runs and five hits in six innings. Kuroda (2-3) had better stuff. He allowed just four singles in seven innings, and against David Robertson in the eighth and Mariano Rivera in the ninth, the Orioles had little chance.

"I have been very consistent this year along with everybody else," Hammel said. "We'll win some 2-1 ballgames, too."

Markakis said there were a few factors that encouraged him to try and score. Third base coach DeMarlo Hale warned him that Kuroda, who had just thrown one wild pitch and nearly another on Davis' strikeout one batter earlier, could do it again.

"It's not like we had 10 hits, 12 hits. A lot played into the situation," Markakis said.

"It's a good play," Showalter said. "They have to make a great play to get him out. I would be upset if he wasn't aggressive and trying to do something there in a close ballgame like that. Usually, the aggressor wins."
