Singapore GP: Lewis Hamilton leads opening practice
Lewis Hamilton ended first practice for the Singapore Grand Prix atop the order in his Mercedes
The Briton led the Red Bulls of Mark Webber and Sebastian Vettel in a tentative session that took a long time to get going as even backmarkers waited for track conditions to improve.
The majority of order changes at the front took place around the halfway point.
In a busy few minutes, the early pacesetting Williams duo and McLaren's Sergio Perez were usurped as the Red Bulls and Mercedes took control.
Hamilton, Nico Rosberg and Webber swapped the top spot several times before Hamilton's 1m47.055s secured practice one honours.
Webber was 0.365 seconds slower in second, with Vettel half a second further back but achieving his best time near the end of a long run.
Rosberg completed the top four ahead of Lotus team-mates Kimi Raikkonen and Romain Grosjean. The latter's running was limited by a steering problem.
Fernando Alonso was the fastest Ferrari in seventh.
Perez fell back to eighth, six places ahead of McLaren team-mate Jenson Button,
Felipe Massa was also outside the top 10 in the second Ferrari in 12th as Toro Rosso's Jean-Eric Vergne and Sauber's improving rookie Esteban Gutierrez claimed ninth and 10th, with Pastor Maldonado's Williams 11th.
The 22 race drivers took part in the session, with no one standing aside for a reserve as teams preferred to maximise their lead racers' track time on the tricky Marina Bay street track.
