Keys will start at designated hitter and bat seventh in Sunday's game against the Mariners.
Keys will collect his fifth start in a row after going 3-for-15 with a home run, a double and three RBI over the previous four contests. His run as an everyday player could end soon, however. The Blue Jays could get George Springer (personal) back from the family medical emergency list as soon as Monday, and Keys is likely to fade into a bench role or return to Triple-A Buffalo at that point.
