Novak Djokovic was all but perfect in his second-round match Wednesday against Ryan Harrison, beating the 20-year-old American 6-1, 6-2, 6-3 to stay on track for his third consecutive Australian Open title and the fourth of his career.

Djokovic, a loser in the U.S. Open final last year to Andy Murray, looks like he wants to atone for that defeat. He was relentless in beating the overmatched Harrison, winning the first set in just 20 minutes and the match in 1 1/2 hours while making just 16 unforced errors.

"I tried to focus from the start," Djokovic said. "Obviously, I knew he had nothing to lose, he's going to come out and hit big serves. Pity for him, I don't think he played his best."
