Stockinger had defended his lead at the start with Daniel Abt trying to sneak past Antonio Felix Da Costa but the Lotus GP driver had to hold station. After two laps behind the safety car, racing resumed.
Abt in third place was a few seconds back from the leading two and was shadowed by Evans in fourth. Further back were David Fumanelli, Kevin Ceccon, Aaro Vainio and Tio Ellinas.
The action in the first race was down the field in the second half of the race when Daly caught the back of Dmitry Suranovich at the hairpin and the Russian driver lost his rear wing.
As Suranovich continued racing, struggling to keep control, Daly made contact with the rear of the crippled car as they came out of the tunnel. Daly became airborne, hitting the high debris fence at the side of the circuit. Stockinger recorded his debut victory in GP3, as the result was declared after 13 laps. Felix Da Costa took second with Abt achieving his first podium in the GP3 Series. Evans, Fumanelli, Ceccon, Vainio and Ellinas rounded out the top eight.
The result makes it four different winners from four races this season. Vaino heads the standings on 54 points with Evans second overall on 43 and Stockinger on 39.
The third round begins in Valencia on June 22.
