AUSTIN (AFP) - Nico Rosberg will start on pole for the United States Grand Prix after Sunday's delayed and curtailed rain-hit qualifying in Austin.

Organisers at the Circuit of the Americas cancelled the third qualifying session as conditions worsened with the race grid based on results from the second qualifying session topped by Rosberg.

The German's Mercedes teammate, Lewis Hamilton, will start alongside him on the front row in the race due to be staged later Sunday.

Red Bull duo Daniel Ricciardo and Daniil Kyvat are on the second row after posting the third and fourth fastest times. Hamilton can clinch his third world title in Texas if he scores nine more points than Ferrari's Sebastian Vettel and two more points than Rosberg.

Qualifying had to be held over from Saturday as the circuit was hit by treacherous wet and windy weather.
