Nadal, Halep roll on as shocks rattle Australian Open

Croatian 19th seed Donna Vekic also crumbled to lower-ranked opposition
MELBOURNE (AFP) - World number one Rafael Nadal and Wimbledon champion Simona Halep dodged an exodus of seeded players as the shocks kept rolling at the Australian Open on Saturday.
After Serena Williams and title-holder Naomi Osaka fell by the wayside on Friday, second seed Karolina Pliskova crashed out on a day of carnage in the women’s draw.
Switzerland’s Belinda Bencic, the sixth seed, won only one game against Estonia’s Anett Kontaveit, the world number 31, as she bombed 6-0, 6-1.
And a resurgent Garbine Muguruza, a two-time Major-winner, thrashed fifth seed Elina Svitolina 6-1, 6-2 as six of the top 10 women’s seeds exited in round three. Tenth seed Madison Keys lost to Maria Sakkari on Friday.
"I was very concentrated and focused on what I wanted to do, it all went fast my way," said Muguruza, who raced through the first set in just 23 minutes.
Croatian 19th seed Donna Vekic also crumbled to lower-ranked opposition when she lost 7-5, 6-3 to Poland’s Iga Swiatek, who is returning from a stress fracture in her foot.
While the women’s seeds fell, Nadal had few problems against fellow Spaniard Pablo Carreno Busta -- despite staying up to watch Roger Federer’s thrilling late-night win over John Millman, which went to a fifth-set tie-breaker.
"I watched it until one o’clock -- it was impossible to sleep watching this match," Nadal said.
But he showed no signs of tiredness, racing through 6-1, 6-2, 6-4 in just 1hr 38mins in what he called his "best match of the tournament so far, without a doubt".
"I’m improving every day, so super-happy. I did well on my serve and hit good forehands down the line, which is a key shot for me," he said.
