MLB: Baltimore 7, N.Y. Yankees 3

NEW YORK, Sept. 12 (UPI) -- One of three hits by Brian Roberts Saturday was a grand slam that sent the Baltimore Orioles to a 7-3 victory over the New York Yankees.

The slam, Roberts' 15th homer this season, gave Baltimore a 6-1 lead with one out in the top of the second.

Nolan Reimold hit a solo homer, and Robert Andino and Jeff Fiorentino also drove in runs for the Orioles, who have won four of six and can sweep the three-game series with a win Sunday.

Winner Brian Matusz (5-2) surrendered a run and just four hits in seven innings.

Mark Teixeira, Melky Cabrera and Jorge Posada all had one RBI for the Yankees, who were held to seven hits and have lost two straight games for the first time since Aug. 16-17.

The losing pitcher was starter A.J. Burnett (11-9).
