The Mariners are in desperate need to turn things around following four straight losses to the Toronto Blue Jays. They'll have Yovani Gallardo on the hill who is 1-3 on the year with a 4.58 ERA. Oakland will counter with Sean Manaea who is going to pitch after a stint on the disabled list with a shoulder injury. Prior to getting hurt, he has a 5.18 ERA and 1.19 WHIP in five starts. The Mariners are 5-1 in their last six home games facing a team with a losing record. Oakland is 2-10 in their last twelve road games. Look for Seattle to rebound in this one behind their tougher bats.
