Vitaly Petrov put in a faultless performance to win a tricky wet GP2 Asia sprint race at Sepang.
The start was delayed by around half an hour after a monsoon swept across the track as the cars went to the grid. The race was eventually started behind the safety car, with Sakon Yamamoto, having been pushed into the pit lane, failing to get away. The field ran a full four laps under caution before it was released on a track that was still well and truly soaked.
Pastor Maldonado gave pole man David Valsecchi a tap at the last corner even before they took the green flag, but both survived and Valsecchi held on to the lead in the difficult conditions. James Jakes was an early victim of the conditions, spinning off on the first flying lap.
On the second racing lap both Maldonado and Vitaly Petrov slipped past Valsecchi, and the pair gradually dropped the Italian.
Petrov then took the lead in a neat move, and with the track gradually drying out, he stayed there to the flag, steadily edging away until the race was ended a couple of laps early when the time limit clicked in.
Behind Maldonado and Valsecchi, Saturday sprint winner Diego Nunes moved up from eighth on the grid to fourth, while Hamad Al Fardan put in a solid drive to fifth.
The final point went to Sergio Perez, who snuck ahead of Kamui Kobayashi in a cheeky move at the last corner.GP2 sprint race results
