(AP Photo/Hamish Blair)MELBOURNE – Rafael Nadal didn't make it for Spain's ATP Cup opener because of a sore back, deciding it wasn't worth the risk a week ahead of the Australian Open.
Nadal played more of a hand in that, with Djokovic limiting his time on court because of a blister.
Back at Melbourne Park, where he has won a record eight Australian Open titles, he had plenty of energy to consume.
Osaka, who won the U.S. Open last year and the Australian Open in 2019, will next face No.
