Yastrzemski is out of the lineup for Monday's game in Philadelphia.
Yastrzemski will sit for the third time in Atlanta's four-game series with Philadelphia, with two of those absences having come against left-handed pitching. Since the All-Star break, Yastrzemski has turned in a lackluster .214/.287/.393 line over 37 games, and his underwhelming production could put him in danger of losing his strong-side platoon role and becoming more of a part-time player versus right-handed pitching.
