Stanton progressing in running program

MIAMI -- Pinpointing a target date for Giancarlo Stanton's return remains up in the air.

The Marlins' slugger is hopeful to return before the All-Star break, but right now, everything is a guess.

Stanton went on the disabled list on April 30 with a strained right hamstring. He has done some hitting in the cages and is playing catch.

"I'm hitting and throwing," Stanton said. "That's good that I can do that."

But as for running, Stanton has progressed from doing jogging in a therapeutic pool to running on a special anti-gravity treadmill, which he has done the past two days.

Stanton is recovering from a Grade 2 hamstring strain, which roughly takes four to six weeks from which to recover.

"I don't know how long it's going to take," Stanton said. "Once I can do normal jogging and running, it will be better to figure that out."
