Karolina Pliskova has continued her perfect start to 2017, breezing into the second round of the Australian Open with a straight-sets win.

The Brisbane International winner was wayward on serve but ruthless once the ball was in play, thrashing Sara Sorribes Tormo 6-2 6-0 on Tuesday.

The US runner-up missed last week’s tournament in Sydney due to a leg injury but was unhampered as she bashed 26 winners past her Spanish opponent.

She however admitted being struck by a bout of nerves during the opening stages of her clash on Rod Laver Arena.

Just half of the Czech’s first serves landed in but it mattered little, with Sorribes Tormo unable to offer much resistance.

“I had a few days off after Brisbane…now everything is fine,” the fifth-seed said.

“I was a little bit nervous in the beginning (and) made a lot of mistakes on my forehand, especially on first serves.

“But overall, in the second set, my game improved a little bit..but not the best, I would say.”

Temperatures were well above 30C when Pliskova took to the centre court but she was unfazed by the heat.

“I felt okay but I was there an hour, so… I think if I would stay longer, it would be worse.”

Pliskova is equally unperturbed by the extra attention she has received since beating Serena Williams, progressing to the US Open final last year and leaping into the top-ten.

“I heard few stuff, but I’m not thinking about this,” the world No.5 said.

“I just don’t want to get it into my head. I just want to continue in those things what I was doing the second half of the year last year and even in Brisbane.

“I think there are still better players than me.”

Pliskova next faces Russian qualifier Anna Blinkova, who upset world No.32 Monica Niculescu in a topsy-turvy 6-2 4-6 6-4 match over two hours and 16 minutes.
