Hungary GP3: Mercedes junior Esteban Ocon tops free practice

The ART Grand Prix driver set the pace after the session was red flagged, as a result of Nissan protege Jann Mardenborough's stricken Carlin entry stopping at the final corner.

On the restart, the Frenchman set some blistering lap-times and was more than a second clear of the rest of the field with less than 10 minutes remaining.

Trident's Ghiotto, however, closed the gap to Ocon to just 0.038 seconds on his penultimate lap but couldn't knock him off top spot.

Arden International driver Emil Bernstorff followed the pair in third, ahead of Silverstone race winners Marvin Kirchhofer and Kevin Ceccon.

Pal Varhaug and Mitch Gilbert both spent time at the top of the timesheets early in the session but fell down the order late on, and the pair finished sixth and seventh respectively.

Lotus Formula 1 team test driver Adderly Fong was eighth ahead of Ferrari junior Antonio Fuoco and Trident's Arthur Janosz, who rounded out the top 10.

Following his issues, Mardenborough, who had been on the pace early on, finished the session last, almost four seconds off Ocon.
