Twins outfielder Darin Mastroianni will report to the team's spring training facility in Fort Myers, Fla. Sunday, to continue his rehabilitation from a left ankle injury.

Mastroianni is on the 60-day disabled list and will work out in Fort Myers until he is ready to start a rehab assignment. Mastroianni has not played since April 15, and there is no timetable for his return to action.

"I'll be starting basically a mini-spring training," Mastroianni told MLB.com Thursday. "I'm not ready to play in games. So it's going to take a little while to get my legs underneath me and get into playing shape. So hopefully it won't take too long, and I can get rocking and rolling. But we don't know how the ankle is going to react. So it just depends on when I get in that first rehab game. We'll play it by ear."
