SEATTLE (AP) Seth Smith hit his first career grand slam, homering for the fourth straight game and leading the Seattle Mariners over the Baltimore Orioles 9-4 Sunday for a four-game sweep.

Seattle had 31 runs and 47 hits, including 23 for extra bases, in sweeping the AL East leaders.

Hisashi Iwakuma (8-6) allowed four runs and 10 hits in six-plus innings.

Ubaldo Jimenez (5-8) gave up six runs and six hits in 4 1/3 innings.

With the game scoreless in the third, Chris Iannetta walked leading off, Ketel Marte blooped a single and Leonys Martin reached when he bunted, Jimenez picked up the ball and looked to throw to third, only to find Manny Machado and charged in and the base was uncovered. Smith's 10th homer put the Mariners ahead 4-0.
