Warren)SEATTLE – Kyle Lewis sparked Seattle’s rally with a two-run homer and walked with the bases loaded in the sixth inning, helping the Mariners top the Oakland Athletics 6-5 on Monday in the opener of a doubleheader. But Seattle chipped away and scored twice in the sixth inning against Oakland’s bullpen to move in front for good. The win pulled Seattle within one game of idle Houston for second place in the AL West. Lewis hit his 10th homer in the fifth inning to pull Seattle within 5-4 and end Luzardo’s day. A’s manager Bob Melvin planned to play Lamb in the second game of the doubleheader.
