BALTIMORE (AP) - J.J. Hardy hit his fourth career grand slam during a seven-run sixth inning, Nelson Cruz connected for his major league-leading 35th home run and Ryan Flaherty also homered, leading the Baltimore Orioles over the Minnesota Twins 12-8 on Sunday.
Caleb Joseph had a career-high four hits for the Orioles, who extended their AL East lead over the second-place New York Yankees to nine games.
Baltimore will seek to complete its first four-game home sweep of the Twins on Monday. The Orioles did, however, take all five games of a home series with Minnesota in 1966.
Wei-Yin Chen (14-4) allowed four runs and eight hits in 6 2-3 innings. The left-hander is 7-1 in 10 starts since June 28.
Minnesota made it interesting by scoring three runs in the ninth before Zach Britton served up a double-play ball for his 31st save.
