The Blue Jays swept Seattle in a four-game series in Toronto last month, but couldn't carry that over to Safeco despite seemingly owning a home-field advantage with more than half the crowd of 33,518 cheering them on. Joe Biagini allowed just five hits and three runs over seven innings, but took the loss as he fell to 1-5 with a 3.38 ERA.
Jose Bautista was 2-for-3 with a solo home run for Toronto, which fell to 29-32 with just its six loss in the past 17 games.
Rookie right-hander Sam Gaviglio continued his outstanding run as a fill-in starter for the injury-plagued Mariners rotation as he limited Toronto to two runs -- just one earned -- on six hits over six innings.
