Rays manager Kevin Cash said Thursday on MLB Network Radio that Diaz (personal) is expected to rejoin the team before Friday's game against the Reds, Jim Bowden of The Athletic reports.
Diaz has been on the restricted list and away from the club since the start of the second half while dealing with a personal family matter, but it appears his absence will not extend any longer. The Rays already have an open roster spot after trading Randy Arozarena to the Mariners, so they won't need to make a corresponding transaction for Diaz.
