Bailly quickest again at Portimao

The 20-year-old Belgian took his place at the top of the timesheet early in the half hour and stayed there throughout - improving his best time late on.

Though Bailly's advantage was much less than in the day's earlier session after Jack Clarke jumped up to second at the end, finishing just 0.034s shy.

"I am really pleased to have gone fastest," said Bailly. "It's good to follow up my win at Zolder by setting the pace here, as I am sure some people will feel my victory was a one-off.

"Going quickest in practice doesn't mean I will be fastest in qualifying, but it is a good start to the weekend."

Kazim Vasiliauskas and Jolyon Palmer were third and fourth quickest, with Will Bratt and Ricardo Teixeira rounding out the top six.

Sergei Afanasiev had an off at Turn 4 early in the session and Plamen Kralev later spun at the Turn 5 hairpin.
