Texas - Lewis Hamilton got the victory he needed to keep his Formula 1 championship hopes alive, winning the US Grand Prix for the fourth time in five years Sunday.
Hamilton cut Mercedes team mate and championship leader Nico Rosberg's points lead to 26 with three races to go.
As it happened: 2016 United States GP
Rosberg finished second ahead of Red Bull's Daniel Ricciardo to maintain a relatively comfortable cushion over Hamilton in the title chase.
The chase is on
Rosberg doesn't have to win any of the final three races to get his first F1 championship, even if Hamilton wins all of them. Two more seconds and a third place will wrap it up. But that also means Rosberg can't afford a bad race if Hamilton is going to make a late charge.
Hamilton started from pole position and got one of his best starts of the season to hold position for his seventh victory of the season.
"Yeehaw!" Hamilton roared over his car radio as he rounded the final turn for the checkered flag and his 50th career win.
Hamilton has called the Texas race "good hunting ground" for him and the perfect place to make a run at Rosberg.

Rosberg has said he won't settle for the safety of second place and will push for wins over the final stretch of the season as he chases a first career title that would match father Keke Rosberg's 1982 championship.

Ferrari's Sebastian Vettel finished fourth.
Haas in points
