Mercedes' Lewis Hamilton and Nico Rosberg sped away to their fourth straight one-two finish at the Spanish Grand Prix on Sunday in a dominant performance that does not bode well for the rest of the Formula One field.

Hamilton took off from pole position and stayed ahead of Rosberg for a fourth consecutive victory to move ahead of his teammate in the overall standings.

Hamilton's 26th career win gave him 100 points after five races and three more than Rosberg, who closed to within one second of his teammate late but again couldn't find his way past his main rival.

Hamilton hasn't lead the championship since June 2012 after winning the Canadian GP with McLaren.
