Valtteri Bottas completed a clean sweep of Formula 1 practice sessions for the Portuguese Grand Prix after edging out Mercedes team-mate Lewis Hamilton for top spot in FP3.
Bottas headed the timesheets in both FP1 and FP2 at Portimao, and was able to maintain his advantage over Hamilton in the final practice session on Saturday morning.
After both Mercedes drivers reported a lack of grip and struggles getting up to speed at Portimao on Friday, they were quickly able to beat the benchmark set during a messy second practice session that was interrupted by red flags and stoppages.
Bottas and Hamilton opted to focus on soft compound tyre running through the session, trading fastest times back and forth.
Hamilton was able to set the initial pace for Mercedes, only for Bottas to hit back and ultimately set a time of 1m16.654s to edge out his team-mate by 0.026 seconds.
Although the lap was set with 25 minutes remaining in the session, it was enough to give Bottas P1 as drivers focused on higher fuel runs towards the end of FP3.
Hamilton lost one of his final qualifying simulations on the soft compound tyre after making a mistake at Turn 8, causing him to run into the gravel.
Max Verstappen was left to settle for third place for Red Bull, but briefly took top spot after beating Hamilton’s initial benchmark, only for his time to be deleted after he exceeded track limits at Turn 1.
The Dutchman ultimately finished the session 0.158 seconds shy of
