The rivalry between Lewis Hamilton and Max Verstappen this season continued in Portugal as the seven-time F1 champion narrowly held the upper hand at the end of second practice.
After Red Bull driver Verstappen was edged by Hamilton's team-mate Valtteri Bottas in FP1 by just 0.025secs, the Dutchman had to settle for second best again in FP2 as the Briton finished 0.143s clear with a lap of one minute 19.837s.
That time was almost two-tenths of a second slower, however than Bottas' leading time from the first session over the undulating Algarve circuit that has been dubbed 'the rollercoaster' due to its wild, undulating nature.
FP2 started 10 minutes later than planned as repairs were required to repair a loose drain cover.
On F1's debut at the track last year, FP3 was delayed by 45 minutes after Sebastian Vettel broke a drain cover by running over one while then with Ferrari.
On this occasion, the delay was not too detrimental before the teams took to the track, only for Verstappen to soon return to the garage after complaining about a brake-by-wire issue.
Verstappen ended up losing 12 minutes of running overall due to what was eventually determined as a brake sensor issue sustained on his first outing.
Come the conclusion, the 23-year-old was again left as 'the meat' in a Mercedes 'sandwich' as Bottas was third quickest, a third-of-a-second adrift of Hamilton.
Ferrari's Carlos Sainz fared well as the Spaniard was fourth, followed by Alpine duo Fernando Alonso and Esteban Ocon. The quartet from Bottas to Ocon were covered by just 0.054s.
