Vitaly Petrov put his experience and skills to good use on a wet and slippery track to claim victory in the second event of the GP2 Asia Series weekend at Sepang.

Rain started to fall heavily on the grid before the formation lap, and the race was delayed for thirty minutes before the start was eventually allowed behind the safety car on a soaked track. The field trailed around at reduced pace for four laps before being released, and polesitter Davide Valsecchi has a tough time keeping Pastor Maldonado behind him even before crossing the line, the Venezuelan making contact with the rear of the Durango car as they shaped up to join the main straight.

Although Valsecchi survived the premature attention, he could not resist forever, and eventually ceded the lead at turn two on lap five, and then saw Petrov go through almost immediately, the Russian looking the more sure-footed in the conditions. Five laps later, the Barwa racer started to put huge pressure on Maldonado, keeping the ART man on his mettle until finally passing him in a strong move at the last turn.
