BOSTON – B.J. Surhoff hit a grand slam, and the Orioles capitalized on the third straight poor start by a Boston pitcher to beat the Red Sox 9-6 last night.

The Red Sox failed to take advantage of the Yankees’ 6-3 loss to Toronto and remained 4 1 /2 games behind AL East-leading New York. Boston lost in New York 11-1 and 14-4 on Saturday and Sunday.

Starters Derek Lowe and Pedro Martinez struggled in those games. On Monday, Tim Wakefield (11-10) lost his control after three strong innings and fell to 0-3 in four starts.

The Red Sox stranded runners in scoring position in five of the last seven innings, fell to 4-8 against Baltimore and suffered their first three-game losing streak since dropping four straight from June 29 to July 2.

Jason Grimsley (5-6) got the win after starter Matt Riley was replaced with two outs in the fifth and runners at second and third. Todd Williams replaced Riley, but pitched poorly and Grimsley was given the win by the official scorer.

Jorge Julio pitched the ninth for his 22nd save in 25 chances.

Wakefield struck out six in 3 1/3 innings then fell behind 5-0 in the fourth.

Wakefield matched season highs by allowing eight runs and five walks and striking out seven. Riley missed a chance to end a nine-start losing streak.
