Yastrzemski isn't in San Francisco's lineup for Friday's game against Arizona, Susan Slusser of the San Francisco Chronicle repors.

EDGE Analysis

Left-hander Jordan Montgomery will start on the mound for the D-backs, so the left-handed bat of Yastrzemski will stay put in the dugout to begin Friday's game. His absence will allow Austin Slater to start in right field and bat in the leadoff spot.
