Toro Rosso team drops Speed

LONDON -- Scott Speed, the only American driver in Formula One, was dropped by the Toro Rosso team and replaced by Germany's Sebastian Vettel.

Speed and fellow Toro Rosso driver Vitantonio Liuzzi are among seven drivers without a single point after the first 10 of this season's 17 races. The 24-year-old Speed, from Manteca, California, has failed to score a point by finishing in the top eight of any race in his two seasons in F1.
