MELBOURNE - Nature-lover Novak Djokovic strolled into the Australian Open third round on Thursday as an erratic Madison Keys did enough to keep her title defence on track and Iga Swiatek also triumphed.
Men's title-holder Jannik Sinner is also in action later on day five at a sunny but cooler Melbourne Park, which fell briefly silent in the evening to remember the 15 people killed at Bondi Beach last month.
Djokovic sent 141st-ranked qualifier Francesco Maestrelli packing in straight sets at Rod Laver Arena.
The Serbian great is on his latest mission to win a record 25th Grand Slam title and dismissed the Italian 6-3, 6-2, 6-2.
Djokovic faces 75th-ranked Botic van de Zandschulp of the Netherlands next.
Djokovic is well known for his sometimes unusual preparations, which include hugging a Brazilian fig tree in Melbourne's botanical gardens.
Keys blew hot and cold before getting over the line 6-1, 7-5 against fellow American Ashlyn Krueger.
Keys, who upset Aryna Sabalenka in last year's final, admitted after her laboured first-round win that she was a bundle of nerves and "too timid".
Second seed Swiatek, who has won six major titles but never been successful in Melbourne, was in cruise control against Marie Bouzkova of the Czech Republic.
"I'm trying to appreciate every match, and take nothing for granted," said the Pole after a 6-2, 6-3 victory.
