San Francisco Giants outfielder Austin Slater isn’t in the starting lineup for Wednesday’s matchup with the Kansas City Royals and right-hander Jonathan Heasley. Slater is batting .241 with a .373 on-base percentage, three home runs, and a pair of stolen bases this season. He’ll head to the bench with a right-hander on the mound for Kansas City. Instead, Mike Yastrzemski will step in as San Francisco’s center fielder and bat second. Yastrzemski is in the midst of a productive season at the plate, batting .275 with a .380 on-base percentage and six home runs in 205 plate appearances. He’s a quality streaming option on Wednesday for fantasy managers looking for outfield options.
