Alberto Cerqui scored his first win in the International Superstars Series with a dominant victory in Race 1 at Misano.
The 19-year-old Team BMW Italia driver held onto his lead from pole position and kept it for the duration of the race, taking the checkered flag with an advantage of 7.5 seconds.
Cerqui's teammate Biagi started alongside him on the front row, but was jumped by both Luigi Ferrara and Luca Rangoni in their Mercedes at the rolling start, demoting the defending champion to fourth.
Rangoni, making his series return this weekend, then made a mistake though which let Biagi through into third. Rangoni would soon regain the place, but he ran wide again later in the race. This allowed Biagi through into third for good, finishing the race just behind runner-up Ferrara.
Another slide wide for Rangoni later in the race dropped him to fifth behind Johnny Herbert at the finish. The Briton had climbed from tenth on the grid in his Romeo Ferraris Mercedes.
Andrea Bertolini finished sixth in his Swiss Team Maserati, ahead of the two Mercedes of Riccardo Romagnoli and Andrea Dromedari. Sergio Hernandez finished ninth in his Campos Racing BMW ahead of the Motorzone Chevrolet of Fabrizio Armetta.
