Austin, October 20: Lewis Hamilton's hopes of sealing a fifth Formula One championship at the United States Grand Prix this weekend have been boosted by nearest title rival Sebastian Vettel incurring a three-place grid penalty.
Ferrari driver Vettel was punished for failing to slow down sufficiently under red-flag conditions during Friday's first practice session in wet weather at the Circuit of The Americas in Austin.
Hamilton has a 67-point advantage in the overall standings having won the previous four races, and a fifth successive victory would be enough to ensure the Mercedes driver claims the title this weekend should Vettel finish third or lower.
And Hamilton looked like a man determined to do his part in that equation when he topped both of Friday's practice sessions.
