NEW YORK -- Hideki Matsui got the ball rolling with a two-run homer, Jorge Posada chipped in with his own two-run shot and Derek Jeter added a pair of solo home runs as the New York Yankees beat the Baltimore Orioles 8-7 Tuesday night.

Coming off last week's three-game sweep in which they outscored Baltimore 41-17 at Camden Yards, the Yankees backed Mike Mussina (6-4) in his fifth straight victory.

Matsui connected on a shot to right off Sidney Ponson in the second inning for his ninth homer of the season to tie the game at 2-all at Yankee Stadium.
