Weeks will bat second in the lineup and serve as the designated hitter Sunday against the Athletics. The Mariners seem to have abandoned the idea of using Weeks at second base, as he's played exclusively at left field and DH this season. Austin Jackson's presence on the disabled list creates some day-to-day uncertainty with the team's starting outfield, but Weeks probably won't be a part of that conversation most nights. He's batting just .208 with two homers over his 55 plate appearances.
