Fernando Alonso's Singapore Grand Prix victory launched him into the Castrol Rankings top five for the first time.
The Ferrari driver qualified on pole position and twice had his lead slashed by the safety car, forcing him to resist the charging Red Bull of Sebastian Vettel over the last few laps. His fourth win of the season not only launched him back into contention for the Formula 1 World Championship; it also gained him two places in the Castrol Rankings.
In climbing to fifth, the Spaniard overhauled Jimmie Johnson – who won the NASCAR Sprint Cup race at Dover – and IZOD IndyCar Series leader Will Power, both of whom lost a spot.
Vettel's second place in Singapore kept him at the top of the Castrol Rankings for a 27th consecutive week, although his Red Bull teammate Mark Webber – third in Malaysia – did erode his points advantage slightly. Webber was central to the most crucial incident of the race as he and his chief title rival Lewis came together on lap 35, the McLaren driver retiring with damaged suspension.
Had Hamilton finished in what was fourth place at the time of his elimination, he would have passed World Rally Championship leader Sebastien Loeb for third in the Castrol Rankings. Instead he remains fourth but with an increased points deficit to the Frenchman.
Robert Kubica's late spate of passing moves allowed the Renault driver to climb to seventh in Singapore and gained him two spots in the Castrol Rankings, to 11th. Ahead of him is Denny Hamlin (10), who moved up a spot with his Sprint Cup result at Dover. Former series leader Kevin Harvick finished back in 15th and dropped two spots to 12th.
Good recovery drives from Nico Rosberg (14) and Felipe Massa (21) in Singapore netted the pair gains of three and four places, respectively, while Rubens Barrichello sunk to 25th – his lowest position since June 2009 – after failing to match his victory in the corresponding race last year.
