Rafael Nadal has ground his way into the Australian Open third round, seeing off qualifier Yannick Hanfmann to continue his unbeaten start to the summer.
Nadal was scratchy at times, converting just four of 16 break points, and took more than two and a half hours to defeat the gritty German 6-2 6-3 6-4 at Rod Laver Arena.
The world No.6 credited Hanfmann, his 2019 French Open first-round opponent, with making his life difficult off the back of an impressive win over Australian Thanasi Kokkinakis.
"The result against Thanasi in the first round here says that he was playing great and coming from the quallies, he was used to the court," Nadal said.
"He's a player with big shots, good serve and with very high potential.
"Today his level of tennis was much higher than what his ranking says, without a doubt."
Pleasingly for Nadal, in his strong start to the Open, after claiming the Melbourne Summer Set, he has shown no signs of lingering fitness issues from last month's bout of COVID-19, or his 2021 injuries.
The 35-year-old is the only player who can claim a record 21st men's grand slam singles crown this month, amid Roger Federer's injury-enforced absence and Novak Djokovic's dramatic deportation.
Nadal reeled off four consecutive games to seal the first set, then had to find another gear to claim the second after some early troubles with Hanfmann's strong baseline game.
The world No.6 broke Hanfmann early in the third set, converting his third break point after a 22-shot rally.
Hanfmann saved two match points on serve when trailing 5-3, then another two on Nadal's subsequent service game, before the Spaniard sealed victory on his fifth attempt.
Nadal will next play either 28th seed Karen Khachanov or Benjamin Bonzi.
