ARLINGTON, Texas (AP) — Nelson Cruz hit his fifth career grand slam, one of four home runs by the Texas Rangers in an 11-3 victory Sunday to complete a three-game series sweep of the Seattle Mariners. The slam by Cruz capped a five-run fifth that chased Aaron Harang (0-2). Leonys Martin, Mitch Moreland and Adrian Beltre (BEHL'-tray) also homered for the Rangers, whose 11 runs were a season high. Martin had a triple leading off the fifth before scoring on Ian Kinsler's bloop single to right. Justin Grimm (1-0), in his fourth major league start, struck out nine and walked one over six innings. Harang allowed eight runs over 4 2-3 innings, and now has a career ERA of 13.22 in four starts at Rangers Ballpark, where he hadn't pitched since 2003.  The only bright spot for the Mariners was Kyle Seager, who had three hits, including his first home run of the year in the 9th.  The home run gave the Mariners three runs for the entire series. That prevented the M's from becoming the first team in the history of Ranger's Ballpark to score only two runs in a three game series.  The Mariners will stay in Texas as they head to Houston to begin a three game series against the Astros tonight.
