Sebastian Vettel, Red Bull dominate day one in India

NEW DELHI (AFP) - Defending world champion Sebastian Vettel topped both practice sessions at the Indian Grand Prix Friday as he bids for his fourth win in a row and a historic third straight drivers title.

The Red Bull driver, 25, who seized the championship lead at the last race in South Korea and is seeking to become Formula One's youngest triple champion, scorched a fastest lap of one minute and 26.221 seconds in the second session.

He finished ahead of his Australian team-mate Mark Webber with Ferrari's Fernando Alonso, the long-time championship leader now supplanted by Vettel, third fastest.

But Vettel later rejected all suggestions that Sunday's race will be a private duel between him and Webber.
