"I think I'll easily be ready for Opening Day," Robertson said. "As long as I have no setbacks, I don't see why I wouldn't [be]. As long as I can play catch a few times, get back on the mound and get a few outings in the games, I'll be set."
Robertson is no longer wearing a walking boot to protect the bone bruise he suffered in his fall.
Robertson was 4-0 with a 1.08 ERA for the Yankees last season in 66 games. He was named to the American League All-Star Team. He is the Yankees' primary setup man for closer Mariano Rivera.
The Yankees had initially feared Robertson's injury was much worse than a bone bruise.
