SINGAPORE (AP) - Mercedes driver Lewis Hamilton set the fastest time in practice for the Singapore Grand Prix on Friday, while teammate and title rival Nico Rosberg and world champion Sebastian Vettel suffered setbacks.
Hamilton s best time of 1 minute, 47.490 seconds at the Marina Bay circuit was a tenth faster than Ferrari s Fernando Alonso, who was also strong in session one when he topped the timesheets.
Rosberg s hopes of bettering his teammate were ruined when his lap on fresh super-soft tires had to be aborted due to a red flag. He was 13th fastest.
Vettel came out for only the last eight minutes of the second session after an engine failure in his Red Bull at the end of the first.
