Mariners 12, Yankees 2: Raul Ibanez hit a grand slam and added a two-run homer as visiting Seattle battered New York to even the series at one game apiece.

Kyle Seager also had a three-run blast to back seven strong innings from Hisashi Iwakuma (5-1), who was staked to a 7-0 lead before throwing a pitch en route to winning his third straight start. Iwakuma gave up two runs on eight hits.

Yankees starter Phil Hughes (2-3) had his five-start unbeaten streak come to a crashing halt, failing to get three outs and getting rocked for seven runs on six hits in two-thirds of an inning.

Ibanez, who has eight RBIs in two games against his former team after entering the series batting .194, went deep for the second straight night with his first-inning grand slam off Hughes to make it 6-0. Michael Saunders added an RBI double later in the inning to end Hughes' night.

Ibanez homered again in the fifth inning to make it 9-2 before Seager hit his fifth homer in the sixth inning. Vernon Wells and Chris Stewart had solo homers for the Yankees, who lost for only the second time in nine games.
