Orioles 7, Yankees 1

NEW YORK -- Brian Matusz pitched 6 1/3 efficient innings, helping Buck Showalter record the 1,000th win of his managerial career as the Baltimore Orioles beat the New York Yankees 7-1 Tuesday night.

The Orioles broke open a close game by scoring three runs -- all with two outs -- in the sixth inning in front of 37,790 at Yankee Stadium.

Showalter is 1,000-958 all-time. His milestone victory came a little more than 20 years after he recorded his first victory with the Yankees on April 7, 1992 -- one day after Camden Yards, his current home park, opened.

J.J. Hardy hit a two-run homer in the third inning to give the Orioles the lead for good. Chris Davis had three hits, including a solo homer. Matusz snapped a 12-decision losing streak dating back to last June by allowing one run on six hits and one walk with four strikeouts.

Matusz and Yankees starter Phil Hughes entered the game a combined 1-6 with a 6.63 ERA, but they were engaged in a surprising pitchers' duel until Hughes walked Matt Wieters with two outs and nobody on in the sixth. New York manager Joe Girardi pulled Hughes for left-hander Boone Logan, who walked Davis and gave up an RBI single to Wilson Betemit.

Nick Johnson, without a hit in his first 28 at-bats of the season, lofted a fly to left, but Eduardo Nunez -- making just his second career start in left and his third appearance overall -- misplayed the ball into a two-base error as Davis and Betemit scored to make it 6-1.

The Yankees took a 1-0 lead on Curtis Granderson's homer in the first but did little else against Matusz, who entered with a 5.10 ERA in eight career starts against the Yankees. Matusz worked out of a two-on, one-out jam in the third, and reliever Darren O'Day escaped a bases-loaded jam in the seventh by retiring Alex Rodriguez on a popup.

Derek Jeter finished 3-for-5 for the Yankees, raising his average to .400. Hughes lasted a season-high 5 2/3 innings and allowed four runs on four hits while walking one and striking out six.

Hughes' spot in the rotation may be imperiled once Andy Pettitte returns later this month. Pettitte, who came out of retirement during spring training, will make at least one more rehab start this weekend.

Hughes looked like a future star when he made the All-Star team as a reliever in 2009 and won 18 games in 2010, but entering Tuesday he had a 7.88 ERA in four starts this year and a 6.26 ERA in 18 starts dating back to the beginning of the 2011 season.

Hughes has said he needs to be as aggressive as he was as a reliever, and Girardi said he approved of such an approach.

"The idea is to put hitters on the defensive, get ahead of them and make quality pitches," Girardi said Tuesday afternoon. "If that's what he feels he needs to be in more of an attack mode, then yeah. And that's what he did as a reliever. I thought he brought that as a starter when he came back in 2010."

NOTES: Pettitte appeared at Roger Clemens' perjury trial in Washington, D.C., and testified about his HGH usage and the conversations he had with Roger Clemens about HGH. Girardi said he didn't think Pettitte was distracted by his imminent appearance on the stand when he allowed six runs in 5 2/3 innings in an extended spring training game Monday but admitted, "I'm sure it was on his mind. I don't know how it wouldn't." ... Girardi said right-hander Michael Pineda's season-ending right shoulder surgery went well. ... Yankees outfielder Nick Swisher is still expected to miss the remainder of the week with a strained left hamstring. ... Orioles outfielder Nolan Reimold was diagnosed with a bulging disk in his back by team doctors in Baltimore, but manager Buck Showalter said he was hopeful Reimold would rejoin the team for this weekend's series in Boston. ... Showalter said left-hander Tsuyoshi Wada had one more test to undergo before Dr. Lewis Yocum recommends a course of action for Wada, who has a partially torn ligament in his left elbow.
