Roger Federer and Novak Djokovic both reached round four of the Australian Open with straight-set wins - although the Serb suffered an injury scare.
Switzerland's five-time champion Federer beat Richard Gasquet 6-2 7-5 6-4 to progress to the last 16.
Six-time winner Djokovic had treatment on his lower back and leg but saw off Albert Ramos-Vinolas 6-2 6-3 6-3.
"It's nothing major to be concerned about. It's things that surface every day. I guess it's normal," he said.
Djokovic, 30, is playing in his first event since Wimbledon last year after a six-month lay-off with an elbow injury.
