Giancarlo Stanton is aiming to play during the final week of the regular season.
Stanton's season is in jeopardy after he went on the disabled list with a groin strain last week. He suffered a Grade 3 strain and the Miami Marlins put a six-week timeline on the injury.
"I don't think we'll be able to truly assess where he's at until he is doing functional, on-field stuff," Michael Hill said.
Stanton is hitting .244/.329/.496 with 25 home runs in 432 plate appearances this season.
