Marlins manager Mike Redmond said Monday that Giancarlo Stanton (hamstring) is doing baserunning drills at the team's spring training complex in Jupiter, Florida. Stanton had to back off his rehab program last week due to some soreness in his knees, but it didn't set him back too far. While there's no clear timetable from the team, he could begin a minor league rehab assignment soon if there are no further setbacks. Stanton has been sidelined since the end of April with a hamstring strain.
