"He was fine today," Mattingly said. "It's really just me being precautionary with him. We talked yesterday about possibly giving him the day anyway. I want him to play [Sunday]. It's really just being safe with him."
Mattingly is also being cautious with infielder Nick Punto, who was scratched from Friday's lineup due to an in-grown toenail on his right foot.
"We're going to be careful with him, too," Mattingly said. "There's no reason to have to run him out there."
Punto felt well enough to field ground balls and take batting practice before Saturday's game, though.
"It's feeling better," Punto said. "I'm fine to play."
Hanley Ramirez started Saturday's game, but Mattingly the shortstop would not start Sunday. Ramirez is dealing with an irritated nerve in his lower back and has not started consecutive games since Sept. 11-12.
