On July 23, Cozart suffered a season-ending left elbow injury during a collision with a runner at second base. Originally diagnosed as a hyperextension, he required Tommy John surgery to repair a torn ligament.
"It's been rehab for three months ever since the season ended," Cozart said. "Every day, just elbow, elbow, elbow. Finally I get to do baseball -- swinging, fielding, throwing. I'm basically full go. It's a process."
A promising start to his big league career was halted by the injury after just 11 games. He batted .307 with two home runs and three RBIs and put himself on the inside track to be the regular shortstop in 2012.
Cozart will be working out at the Reds' facility in Goodyear, Ariz.
"I'll be beyond 100 percent come Spring Training, proving I am healthy and proving that I think the job should be mine," Cozart said.
