Sergey Sirotkin has set the pace in first free practice for the second GP2 Series round at Monaco as he looks to kick-start his title campaign.
One of the pre-season title favourites, Sirotkin failed to score at the Barcelona opener after spinning out of a podium position in race one, but was on fine form in FP1 at Monaco as he repeatedly improved his benchmark.
He would head up Barcelona race winners Norman Nato and Alex Lynn in second and third, with Arthur Pic and Jordan King completing the top five.
An eventful beginning to the session would see three cars into the wall at Ste Devote, with Pierre Gasly, Norbert Matsushita and Daniel De Jong all striking the outside wall to cause Virtual Safety Cars. Despite the lack of laps, Gasly was still a creditable seventh quickest.
