Federer, Nadal stay on track as Anderson crashes

Roger Federer ground out a tough three-set win to make the Australian Open third round for an incredible 20th straight year Wednesday, with long-time rival Rafael Nadal also safely through.

But it was curtains for South African Kevin Anderson, who slumped out to young American Frances Tiafoe and became the highest seed, at five, to be sent packing so far.

Federer might be 37 but he's not showing his age, with British qualifier Dan Evans the latest to fall under his spell as he works towards a third successive Australian crown and 21st major victory.

He defeated Evans at Wimbledon last year with the loss of just eight games, but it was a much harder assignment this time, winning 7-6 (7/5), 7-6 (7/3), 6-3 on Rod Laver Arena.

"I think if I could have pulled away earlier in the match it might have been easier," said the third seed. "I think he played very well, it was hard to pull away to his credit."

The Swiss star's Australian achievements so far put him on a par with other six-time winners Novak Djokovic and Roy Emerson – although the Australian great's victories all came before the Open era.

He next plays American Taylor Fritz.

Seventeen-time Slam winner Nadal had an easier route to round three, outclassing local hope Matthew Ebden 6-3, 6-2, 6-2.

The Spaniard is bidding for his own slice of history by becoming the first man in the Open era, and only the third in history along with Emerson and Rod Laver, to win each Grand Slam on two or more occasions.

"I played a solid match, I was happy with the way I served. I did a few things very well," said Nadal, who next plays Australian Alex de Minaur. "It is an honour to play here. Was a great atmosphere."

Anderson, beaten by Novak Djokovic in the Wimbledon final last year, was sent home by Tiafoe 4-6, 6-4, 6-4, 7-5.

The fifth seed struggled with an elbow injury early in the clash and couldn't cope with the 20-year-old's power and finesse.

Sixth seed Marin Cilic, who lost in the final to Federer last year, had no such dramas, grinding past American Mackenzie McDonald in four sets.

The Croat now plays Spanish 26th seed Fernando Verdasco, who beat Radu Albot of Moldova.

Another young gun, Greece's Stefanos Tsitsipas, also stayed alive, overcoming a tricky test against Serbian Viktor Troicki in four sets.
