Lewis Hamilton says his healthy lead of the championship is a reward for not putting himself in some of the problematic positions Sebastian Vettel has found himself in this year.
By winning in Singapore, Hamitlon extended his championship lead to 40 points with six races to run. Ferrari was expected to win at Marina Bay but a below-par qualifying, coupled with one of the best laps of Hamilton's career, helped the Mercedes drive claim a shock pole position -- one he converted to victory on the Sunday.
