Murray twists ankle, still wins.

He advances despite spraining ankle

An hour after his win, Andy Murray still hadn’t been able to get any video to see how he twisted his ankle and tumbled to the ground.

Murray’s shoe caught on the surface and he tumbled to the court at Rod Laver Arena, clutching his right ankle and cringing in pain during the third game of the third set against No. 156-ranked Andrey Rublev.

The five-time Australian Open runner-up continued and won that game on Wednesday, but told himself, loudly, “It’s not good news.” He saw a trainer during the next change of ends, but decided he didn’t need any extra treatment on his already heavily braced joint.

He limped on to win, 6-3, 6-0, 6-2.

“I was moving OK toward the end,” he said, “so that’s positive.”

Roger Federer’s progress was straight-forward, beating 20-yearold qualifier Noah Rubin 7-5, 6-3, 7-6 (3) to maintain his record of never failing to reach the third round in Australian Opens.

After back-to-back wins over qualifiers, the 17-time Grand Slam champion’s comeback from a sixmonth injury layoff will increase in the degree of difficulty. Next up, Federer faces 2010 Wimbledon finalist Tomas Berdych, who had a 6-3, 7-6 (6), 6-2 win over Ryan Harrison.

U.S. Open champion Stan Wawrinka, who won his first major title in Melbourne in 2014, advanced, 6-3, 6-4, 6-4, over Steve Johnson and will next play No. 29 Viktor Troicki.

No. 19 John Isner, the highestseeded American in the men’s draw, lost to Mischa Zverev, 6-7 (4), 6-7 (4), 6-4, 7-6 (7), 9-7. But wins by No. 23 Jack Sock and Sam Querrey ended the day on a more positive note for the Americans.

Defending champion Angelique Kerber celebrated her 29th birthday with a 6-2, 6-7 (3), 6-2 second-round win over Carina Witthoeft.
