Slater isn't starting Monday's game against the Brewers.
Although Mike Yastrzemski (illness) was placed on the COVID-19 injured list Monday, Slater will be out of the lineup for a third straight game with right-hander Corbin Burnes on the mound for Milwaukee. Darin Ruf, Luis Gonzalez and Joc Pederson will start in the outfield from left to right.
