Alonso top in tight P2
Hamilton has to settle for second
Fernando Alonso put in a late dash to steal the show in Singapore's Practice Two, which saw the top four drivers separated by just 0.1 seconds.
The session was dominated by Lewis Hamilton, who led the way for most of practice while his rivals tried to chase him down. However, eventually it wasn't Felipe Massa who got the better of him, rather it was Fernando Alonso.
Hamilton, Massa and Heikki Kovalainen, though, weren't far off the pace, all three drivers coming in less than 1.5 seconds behind the Spaniard.
With second practice starting only an hour after the first had finished, race control was quick to announce a two minute delay as organisers rushed to get paddock club guests out of the pit lane.
Nico Rosberg led the train of cars heading out at the start for their installation laps with some opting to stay out and starting setting times.
As such Fernando Alonso, Nick Heidfeld, Kazuki Nakajima and Robert Kubica took the early lead, all immediately hitting below the 1:50s. Nico Rosberg took the P1 slot off Alonso while Seb Vettel went third. He, though, was soon knocked down by Heikki Kovalainen, who went second, and Nakajima who improved to fourth place.
With more drivers heading out onto the track the timesheets continued to roll over like a slot machine as the first ten minutes saw half the field setting times.
Felipe Massa went fourth while Nico Rosberg clocked three fastest sector times to improve his P1 time to a 1:46.835. The Williams driver's reign, though, was put to a rest by Lewis Hamilton, who went quicker.
Rubens Barrichello, with his car repaired after his earlier accident, clocks the 16th best time on his first attempt, 6 seconds off the pace.
Rosberg closes up on Hamilton, bringing the gap down to less than a tenth, leaving Massa and Kovalainen to fight over third place.
Nick Heidfeld made contact with the concrete wall after hitting the kerbs, forcing the BMW driver to pit for checks to see if he had damaged his car.
Kimi Raikkonen is the last driver, barring Mark Webber whose car his mechanics are still busy fixing, to set a time but it's only good enough for 16th place. The Ferrari driver improved to fifth on his next run but was 1.5s off the pace. Hamilton lowers the benchmark to a 1:45.805 while Raikkonen almost loses it at Turn 10 over the kerbs.
Kubica, Raikkonen and Alonso all improved their times as Massa took the escape road at Turn 16. The Brazilian straight-lines it on the following lap as he battles to reduce his speed.
Glock moves up to eighth place with Heidfeld, Nakajima and Giancarlo Fisichella fighting for position behind him. Fisi's fight and session are soon over as he pits with a gearbox problem. Button jumps to ninth place.
With half an hour remaining Mark Webber finally climbed into the cockpit of his Red Bull looking to do his first laps of the session.
Massa made the leap up to second place, however, remained 0.2s off Hamilton's P1 time as the McLaren driver continued to dominate the session. The Aussie clocked a 1:51.666, which kept him down in 20th place. He improves the following lap but not enough to overhaul fellow session one crasher Barrichello.
Massa finally put an end to Hamilton's reign as he edged his title rival by 0.012s. Kovalainen also improved to slot in 0.04s behind Massa. However, both drivers were dropped when Hamilton returned to claim the P1 slot with a 1:45.752, 0.04s ahead of Massa.
It was Alonso, though, who had the last laugh as the Renault driver came through with a 1:45.654 to steal the show.
