EDGE Analysis

Marsh has been used more as a bulk reliever lately, but he won't be following an opener this time. The left-hander will be tasked with holding down a Mariners lineup that hit seven home runs and scored 15 runs Saturday. Marsh has surrendered 12 homers in just 43.2 innings this season.
