F1:Vettel has make 100th Race in Historic One

Sebastian Vettel can make his 100th Formula One race the United States Grand Prix an historic one here on Sunday by creature crowned the youngest ever triple world winner. The 25-year-old German, and his Red Bull team, could make it a night for twice merriment if they take both the drivers' and teams' titles in a country where he made his entrance as a baby-faced 19-year-old stand-in at Indianapolis in 2007. 

That last United States Grand Prix, five years ago, was won by Briton Lewis Hamilton of McLaren and, this time approximately, he will once again be a major candidate for victory in his last but one race for the team before he leaves for Mercedes. 

But both contest leader Vettel and Hamilton know they face a challenge this weekend from two-time champion Spaniard Fernando Alonso of Ferrari who is 10 points at the back the German in the title race and still persuaded he can secure his own third title. 

 Finn Kimi Raikkonen of Lotus, winning in Abu Dhabi, will also be a hazard. Vettel, who restore Pole Robert Kubica at BMW Sauber in 2007, managed to be eligible seventh and finish eighth, his solo point for that feat making him F1's youngest points-scorer a evidence that he still holds. 

As he looked ahead to this weekend's quarrel at the virtually unidentified Circuit of the Americas, a purpose-built track 15 miles from Austin city centre, he confesses he could hardly believe it.
