    • Takes over at top of the F1 standings
    • Mercedes teammate Nico Rosberg forced out of race early
    • Sebastian Vettel takes second for Red Bull
    The F1 title race may have taken a potentially decisive twist Sunday as Lewis Hamilton took ruthless advantage of the misfortune which befell Mercedes teammate and bitter rival Nico Rosberg to win under the Singapore floodlights and leapfrog him in the standings.
    Rosberg, who led by a commanding 22 points coming into the 14th round of the championship, was left stranded in the pit lane after failing to move off his second spot on the grid for the formation lap and later retired as the electrical malfunction could not be remedied.
    Hamilton, who has won two straight races after claiming the Italian Grand Prix earlier this month, has taken a three-point advantage over Rosberg, with five races remaining.

    Rosberg also acknowledged that despite the dominance of Mercedes they still had work to do, with the German the victim of misfortune this time.
    "Sitting on the grid, seeing everybody go by was a horrible feeling," he admitted.
    "Reliability has again proven a weakness, which is something we must improve on."
