Atlanta placed Yastrzemski on the 10-day injured list Saturday with left elbow inflammation.
Yastrzemski had tallied a base hit in each of Atlanta's last five games, but the team will be without his services until at least July 21 while he recovers from the elbow issue. Eli White could be in line for more reps in right field while Yastrzemski is out, though Brewer Hicklen -- who was called up from Triple-A Gwinnett in a corresponding move -- could also be in the mix for playing time.
