The Mariners (34-32) return home to Safeco Field Monday night to start a three game series against their division rivals, the LA Angels (31-36). Seattle has an opportunity to separate themselves from the Angels in the standings and make the AL West division race a two-team battle. The Mariners are currently 1.5 games back from the Texas Rangers, while the Angels are five games back.
Jason Vargas (4-3 3.94 ERA) gets the start for the Mariners. In his last start against the Angels, Vargas pitched seven innings of shut out baseball and struck out a season-high nine Angels batters. The left-hander has won four of his last five decisions.
Taking the mound for the Angels is Dan Haren (5-4 2.41 ERA). Haren went eight innings and only surrendered one run to the Mariners in a start back in mid-May. He has been a dependable workhorse for the Angels this season, he has pitched into the sixth inning in all but one of his 14 starts.
