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.

After going just 3-for-19 with two runs scored and five strikeouts in his last seven games, Yastrzemski will step out of the starting nine Saturday while Mauricio Dubon starts in left field, clearing the way for Ha-Seong Kim to start at shortstop.
