Muguruza happy with form at Aus Open

The Spanish third seed cruised to a 6-0 6-4 win on Rod Laver Arena, needing just an hour to advance into the second round.

Muguruza is considered among the favourites to challenge Serena Williams at the year's first grand slam.

The 22-year-old said her performance was a pleasing way to start her campaign at Melbourne Park.

"It was definitely a good start," Muguruza said.

"Well, you never know how it's going to go, first match always in a grand slam.

"I'm pretty pleased of my level, and obviously that I was really concentrated during the whole match."

Muguruza will face Belgian Kirsten Flipkens in the second round.
