SINGAPORE - Formula One title chaser Lewis Hamilton clocked a red-hot lap of 1min 47.490sec to set the pace after the opening two practice sessions of the Singapore Airlines Singapore Grand Prix on Friday.
The Mercedes star was 0.133s ahead of embattled Ferrari driver Fernando Alonso, who was surprisingly quick on the Marina Bay Street Circuit - even topping the leaderboard at the end of the first practice.
On a humid and muggy evening, four-time world champion Sebastian Vettel was left fuming when mechanical failure sidelined his Red Bull for most of the second session. Team-mate Daniel Ricciardo grabbed third place in the same practice.
Drivers' championship leader Nico Rosberg took third and 13th positions over his two drives. Much will ride on Saturday's qualifying run, as four of the six editions on the tight circuit have been won by the pole sitter.
