Giancarlo Stanton was not in the lineup for the fifth consecutive game Tuesday, but took his first batting practice since suffering a bruised shoulder.
Stanton took several swings hitting the ball often to the warning track. Stanton also did some throwing and catching pregame.
Redmond did not give an exact timetable on when Stanton would return, but said Stanton told him he felt good after swinging the bat.
"We're just going to wait and see how he responds," Redmond said. "He hadn't done anything in five days so we'll see how he feels the rest of the day and look at him tomorrow and go from there. I'm hoping he shows up tomorrow and feel even better."
Redmond said he wasn't leaning toward automatically giving Stanton another day off if he felt a lot better Wednesday.
"We don't want to push him. We want to make sure everything is good."
Outfielder Austin Kearns underwent his follow-up medical tests, and was cleared to play Tuesday night. Kearns was hospitalized Sunday after complaining of an irregular heartbeat.
The Marlins made a tweak to the top of their lineup Tuesday putting Chris Coghlan in the leadoff spot with Juan Pierre batting second.
