Sergey Sirotkin and Sergio Campana emerged as the men to beat in free practice ahead of the first round of the Auto GP World Series at Monza.
16-year-old Russian Sirotkin, last year's Formula Abarth champion, defied his age and lack of experience to record the fastest time in the first of the two sessions. He was 0.269 seconds ahead of Campana, the 25-year-old reigning champion of Italian Formula 3.
Campana, driving for brand new team MLR71, turned the tables on the youngster in the second session, shaving more than a second off the morning benchmark. Euronova Racing driver Sirotkin was second this time, 0.131s behind.
Behind the leading duo, the remainder of the top six was identical in both sessions. GP3 race-winner Adrian Quaife-Hobbs was third fastest in both sessions for Super Nova, ahead of ex-GP2 driver Giacomo Ricci of Zele Racing. Quaife-Hobbs' teammate Victor Guerin was fifth, ahead of fellow Italian F3 graduate Facundo Regalia (Campos).
In the second session Sirotkin's teammate Antonio Spavone was seventh fastest, ahead of GP2 refugee Pal Varhaug – driving for new British outfit Virtuosi. Former British F3 racer Adderly Fong was ninth for Ombra, with gentleman driver Giuseppe Cipriani completing the top ten for Campos.
