MINNEAPOLIS -- Twins manager Ron Gardenhire said before Friday's game against the Rangers that Joe Crede's back was feeling better. But it was not feeling well enough to keep the third baseman off the disabled list.

Following a 3-2 win over Texas, the Twins placed Crede on the 15-day DL with a lower back strain. The move is retroactive to Aug. 22.

Gardenhire said that the doctors felt it would be two to four days before Crede might be able to play again. The third baseman is expected to get his second epidural shot this week. He had the first on Wednesday after an MRI exam revealed that Crede had post-operative damage in his back, following the surgery he had this past offseason.

"They've come in from the top, and now they are going to come in from the bottom," Gardenhire said of Crede's shot. "So he'll get taken care of."

The Twins' doctors have been collaborating with Dr. Andrew Dossett, the Dallas orthopedist who performed Crede's back surgery this past offseason.

To replace Crede on the roster, the Twins will recall catcher Jose Morales from Triple-A Rochester on Saturday. Morales, who batted .343 in 29 games for the Twins this season, will join the club in time for Saturday's contest against the Rangers.

Right-hander Armando Gabino was also optioned back to Rochester after Friday's contest. It's a move that will open up space on the roster for when the Twins announce on Saturday that they've signed left-hander Ron Mahay.
