Hamilton not relinquishing title just yet
Lewis Hamilton will battle to the final race to retain his Formula One crown after cutting Nico Rosberg's lead by seven points in Austin.
For the fifth time his career Hamilton claimed top spot on the United States Grand Prix podium on Sunday, the Briton coming home over four seconds ahead of his Mercedes team-mate.
Despite his win, Hamilton knows if Rosberg finishes second in the final three races he will be confirmed as champion for the first time.
However, the 31-year-old has vowed to push his rival all the way in the closing weeks.
"All I can do is my best and continue to drive as I have this weekend," he said in his podium interview.
"Nico has been driving fantastically well, but the battle will continue, I will be going for it."
Hamilton thanked his Mercedes crew for giving him the tools to go out and collect a seventh win of 2016 - the 50th of his career.
"This has always been a good hunting ground for me, it always feels like home," he added.
"The team did a great job to put us both up there and I am very proud to be up here. Finally my 50th win!"
Rosberg rued a sloppy start that saw Daniel Ricciardo pass him in his Red Bull, but he was content with second as he closes in on that maiden title.
"I lost out a bit at the start but gave everything to come back," he said. "Second place was ok, it was damage limitation, of course.
"But I was going for it flat out until the end [to try and catch Hamilton]."
