Earlier in Spring Training, Stanton missed a week due to a sore right knee.
Missing so much time has delayed Stanton's timing and general feeling at the plate. He entered the day with one RBI before connecting off the Cardinals' closer.
Just seven days away from leaving their Spring Training, the Marlins are hopeful their slugger will start heating up.
"You'll definitely see more of him and everyone else," Mattingly said. "We'll try to keep him off the long trip [Saturday to Kissimmee, Fla., to face Houston]. We'll do a little manipulation as we get closer with him, and get him a lot of at-bats towards the end."
Stanton isn't worried about the results right now. In the final week of camp, he merely is seeking hard contact.
"Not homers," he said. "Just hitting fastballs hard. I don't care if they're outs or whatever."
