Reimold, who has been on the disabled list since May 5 and underwent surgery on June 25, is gaining strength every day and is about four weeks into an eight-week rehab program.
"He's right where he needs to be, if not a little ahead of it," Showalter said. "Everything that the doctors felt like he would start feeling and realizing has happened so far, so that's a good sign."
Reimold was a productive fixture at the top of the O's order in April, hitting .313 with five home runs and 10 RBIs in only 16 games.
After treatment with epidurals did little to relieve the numbness and tingling that were bothering Reimold, he opted to undergo a spinal fusion surgery, the same procedure NFL quarterback Peyton Manning underwent.
Reimold's biggest hurdle is getting his strength back, a process he is preparing to work toward well into the offseason.
"I just want him to continue and not get ahead of himself," Showalter said. "There's some unknown about where he's going to be with range of motion, the whole nine yards. The chances that it's going to be full go, it's in his favor. But we'll see. Anytime you're dealing with a spine and back and everything, you really kind of wait with bated breath regardless of what the experts tell you."
