Diaz has not started in three of the Rays' last eight games.

Diaz is still starting the majority of games for Tampa Bay, but his playing time has slipped as Jonathan Aranda becomes a more consistent presence in the lineup. Diaz's usage against righties is particularly concerning, as he's started only half of the team's last six matchups. It's possible he is dealing with an injury, though the Rays have not disclosed that.
