BALTIMORE (AP) -- J.P. Arencibia hit his first career grand slam, Rajai Davis had three hits and the Toronto Blue Jays beat the Baltimore Orioles 8-4 on Friday night to end a two-game losing streak.
Carlos Villanueva (3-0) allowed two runs and six hits in 5 1-3 innings, walking one. He is 2-0 in three starts since moving into the Toronto rotation from the bullpen.
Arencibia's fifth-inning slam was his ninth homer of the season and gave the Blue Jays a 7-0 lead against Orioles rookie Zach Britton, who has lost three straight decisions after starting the season 5-1.
Toronto has won 21 of 27 games against the Orioles and is 16-3 in its last 19.
J.J. Hardy homered for Baltimore, which has dropped six of seven games to fall five games below .500, matching a season high.
