Beckett was scratched from his Saturday start due to discomfort in the right lat area.
"Beckett threw today, said he felt great," said manager Bobby Valentine. "Well, I don't think he said great. I think he said he felt fine and ready to go."
Beckett doesn't figure to have any pitch count restrictions after missing just one outing.
"It seems like it's a regular start unless I'm told differently," Beckett said.
