DETROIT -- Outfielder Shin-Soo Choo is set to accelerate his rehabilitation program with the Texas Rangers after going through a full running session on Sunday.

Choo has been on the disabled list since April 10 because of a strained right calf. Choo said he went at nearly full speed in base-running and outfield work before the game against Detroit. He has been hitting for more than a week.

If medical personnel approve, Choo will head to the club's base in Surprise, Ariz. on Monday night to begin five days of workouts and games with the extended spring training team.

The next step would be a minor-league injury-rehabilitation assignment for three or four days before joining the Rangers on May 20 for the start of a series at Houston.

"Every day it's getting better," Choo said. "It's the first time I've had this kind of injury. I don't want to do it again. If I do it again, I'd double the rehab time. I'll be careful."
