Hamilton fastest as Mercedes dominate U.S. practice

AUSTIN Texas (Reuters) - Formula One championship leader Lewis Hamilton and his title rival team mate Nico Rosberg were separated by mere fumes on Friday in a familiar Mercedes one-two in U.S. Grand Prix practice.
Just three thousandths of a second separated the two at the end of the day, with Hamilton top in both sessions despite a hydraulics problem that sidelined him towards the end of the second.
"The car felt good today and we were able to improve consistently over the two sessions," said the Briton.
"I only got a couple of laps of my long run which was unfortunate as we lost a bit of track time but Nico got the data for the team so we should be OK.
"These small glitches happen and I'm confident that we won't have problems moving forward."
Hamilton, chasing his fifth successive win and 10th of the season, set the morning pace with a time of one minute 39.941 seconds at the undulating Circuit of the Americas.
Rosberg, 17 points behind his team mate with three races to come worth a maximum 100 points, was 0.292 seconds slower than the 2008 world champion.
Hamilton then produced a 1:39.085 in the afternoon, a massive 1.1 seconds quicker than third placed Ferrari driver Fernando Alonso. The difference between the two was the same as that between Alonso and 16th placed Adrian Sutil. Continued...
