The Reds have put left-handed setup man Bill Bray on the 15-day disabled list with a strained groin that has bothered him since spring training.
The move on Tuesday is retroactive to April 19. Bray gave up four hits and three runs during an 11-1 loss to St. Louis on April 18. The Reds already were missing closer Ryan Madson, out for the season with a torn elbow ligament.
Bray led the staff and finished tied for second in the National League with 79 appearances last season. He missed much of spring training with the strained groin, and made only five appearances before going on the DL.
The Reds called up right-hander J.J. Hoover from Triple-A Louisville. They got Hoover from the Braves in a trade on April 1.
