Luiz Razia converted his reverse grid pole position into a maiden GP2 victory in the Asia series finale in Bahrain today.
The Brazilian held his nerve through a safety car restart after a five-car crash at the start, and had the legs of second-placed David Rigon throughout the race.
The accident at the start was triggered when Roldan Rodriguez and Davide Valsecchi were taken out by Karun Chandhok and Pastor Maldonado, with Rodolfo Gonzalez also involved.
D'Ambrosio had moved up to fourth from sixth off the line and set about chasing Sakon Yamamoto once racing resumed. He caught and passed the Japanese driver and then chased down Rigon in the closing stages of the race to take second place.
Newly-crowned champion Kamui Kobayashi finished fifth, ahead of race one winner Diego Nunes who recovered to sixth after a making a mistake and losing a couple of places at the restart.
