Diaz is out of the lineup for Sunday's game against the White Sox.
He'll head to the bench for the third time in five games and appears to be stuck in a short-side platoon role in the infield. After going 1-for-3 with a walk and a run scored in Saturday's 8-4 win, Diaz is slashing .244/.292/.488 in 24 games since the All-Star break.
