Diaz is absent from the lineup for Wednesday's matchup against Colorado, Ryan Bass of Rays.tv reports.
After a 2-for-5 performance with a double, two runs scored, a walk, a stolen base and two strikeouts Tuesday, Diaz will rest for Wednesday's series finale. Jonathan Aranda will slot in at DH and bat second while Liam Hicks will move over to first base and bat cleanup for Tampa Bay.
