Novak Djokovic stayed on track for a fourth consecutive Australian Open singles title with a 6-0, 6-4, 6-4 win Wednesday over Leonardo Mayer of Argentina.
Advancing to the third round with his 26th consecutive match win, Djokovic had a brief scare while serving at 3-0 in the first set when he turned over on his left ankle, tumbling to the court. (Click for all the latest results and news)
But it wasn't serious enough for him to warrant medical attention during the next break in play and he took the opening set in just 22 minutes, conceding just eight points.
Djokovic is attempting to win a fifth Australian title, the first man to achieve that feat since the Open Era began in 1968.
