McLaren's Lewis Hamilton has dominated practice ahead of tomorrow night's Malaysia Formula One Grand Prix.

Hamilton has topped the time sheets in both the morning and afternoon sessions, with seven time world champion Michael Schumacher second quickest in his Mercedes.

"Going from the front is a much better position to be in so that's what I'm going for," he says.

Reigning world champ Sebastian Vettel struggled to 10th fastest in the afternoon session.
