Diaz is out of the lineup for Sunday's game against the Mets.
Diaz appeared to be in some discomfort after a slide into home plate in Saturday's 8-4 win, but he wasn't removed from the game at any point, and manager Kevin Cash said that the 33-year-old is "totally available" off the bench Sunday, per Marc Topkin of the Tampa Bay Times. Diaz's absence thus looks to be little more than a pre-planned rest day after he had started each of the Rays' last seven games. He's been on a heater of late, slashing .408/.473/.673 with three home runs, 10 RBI and nine runs in 12 games dating back to May 31.
