The Ukrainian boxer was troubled by the 32-year-old only in the fifth round, as he won the judges' scores of 120-107, 120-107 and 119-10 on Saturday.
It was Klitschko's 13th title defence, and after the fight he paid his tribute to his longtime trainer Emanuel Steward, who died last month at the age of 68.
"I want to remember one man, who can't be here today unfortunately," he said. "Emanuel Steward, we miss you, we're thinking of you."
Johnathon Banks is Klitschko's interm new trainer.
