Australian Open: Rafael Nadal through; Dominic Thiem, Fabio Fognini also win

World number one Rafael Nadal cruised into the Australian Open second round with a straightforward victory over Bolivia’s Hugo Dellien in Melbourne.

Nadal, champion in Melbourne in 2009, dropped just five games in a 6-2 6-3 6-0 win over his 72nd-ranked opponent.

The Spaniard, runner-up last year, is bidding to equal Roger Federer’s record of 20 Grand Slam men’s singles titles.

He will play either Federico Delbonis of Argentina or Portugal’s Joao Sousa next.

Nadal has reached the Australian Open final five times but won it only once, beating Federer in a five-set epic 11 years ago.

He dropped serve twice against Dellien but barely looked troubled, hitting 38 winners to his opponent’s 15.

“For me personally it has been a very positive start,” the 33-year-old said.

“What you want is to win in the first round and, if you can do it in straight sets, even better.”

There were also wins on Tuesday for Austrian fifth seed Dominic Thiem, Spain’s ninth seed Roberto Bautista Agut and Argentine 14th seed Diego Schwartzman.

Stan Wawrinka, who won the title in 2014, progressed in four sets, while former finalist Marin Cilic and 2016 semi-finalist Milos Raonic won in straight sets.

‘You’re pathetic’ – Fognini & Opelka clash with umpire

Italian 12th seed Fabio Fognini fought back from a two-set deficit to beat American Reilly Opelka in a bad-tempered match.

Opelka, who had earlier been given a code violation for time-wasting, shouted at the umpire when he felt Fognini should have been penalised for the same thing.

Fognini had earlier sworn at the umpire in Italian and broken a racquet.

After Fognini threw his racquet, Opelka approached Carlos Bernardes and said: “Let me ask you something, real quick. You’re pathetic.

“You give me one warning after one throw. He’s thrown his three or four times, bro.”

Opelka had led Fognini overnight after rain delayed their match, but was ultimately beaten 3-6 6-7 (3-7) 6-4 6-3 7-6 (7-5).

“You don’t want to engage with a guy like that,” Opelka said of Fognini after the match.

“You want to keep him out of the match as much as possible. It’s definitely not a positive thing.”
