TENNIS: American Coco Vandeweghe will play Venus Williams for a place in the Australian Open final after beating Garbine Muguruza and nerves during the quarter-final.

The giant-killer backed up her defeat of world No.1 Angelique Kerber with a dominant 6-4 6-0 victory over the No.7 seed in just one hour and 24 minutes.

Vandeweghe smashed 31 winners past the in-form Spaniard, who had reached the last eight without dropping a set, to earn the first grand slam semi-final of her career.

"I really wasn't feeling all that great out there. I was really kind of nervous,” she said.

"I even told my coach 'better get some toilet paper out there'.”

It took the world No.35 Vandeweghe eight break points to finally crack Muguruza's serve in the first set, before she dominated the second.

"She finally cracked and once I got rolling in the second it was like a freight train, you couldn't stop it,” she said.

"(But) it was really frustrating (during the first set) ... I was second-guessing myself with what to do with the serve.

"Finally I think she felt the pressure and gifted me the double fault (on set point).”

Vandeweghe also beat

15th seed Roberta Vinci in her opening match and former world No.5 Eugenie Bouchard before upsetting Kerber.

Vandeweghe said she would need to push aside her girlhood-adoration for Williams in their next match.

"She's someone I sought after for an autograph way back when ... it took two matches to push through the crowd and get one,” she said.

"It's an honour to play a great champion like Venus.”
