Refsnyder (undisclosed) will start at designated hitter and will bat leadoff in Sunday's game against the Royals.
Refsnyder is typically included in the lineup against left-handers, but he took a seat versus southpaw Cole Ragans in the series opener Friday while he contended with a couple minor injuries. The Mariners felt comfortable enough with Refsnyder's health to use him off the bench in Saturday's 3-2 extra-inning win, and after checking out fine afterward, he'll get the green light to start Sunday versus Royals lefty Kris Bubic.
