Guyer will bat second and start in left field in the first game of Wednesday's doubleheader with the Yankees.
He'll check into the lineup for Austin Jackson, who is getting a breather for the front end of the twin bill. A lefty killer throughout his career, Guyer could make for an appealing cost-effective DFS option for the Wednesday slate with southpaw Jaime Garcia toeing the rubber for the Yankees in Game 1.
