Formula One champion Max Verstappen edged out Charles Leclerc to the fastest time in Friday's practice for the season-opening Bahrain Grand Prix as Red Bull and Ferrari lived up to their pre-season hype while Mercedes appeared to be on the back foot. The 24-year-old lapped the 5.4km floodlit Sakhir track in one minute 31.936 seconds, beating Leclerc by 0.087 seconds. Ferrari's Carlos Sainz was over half a second back in third. “It’s been a positive day for us, really,” said Red Bull team boss Christian Horner. “Both in the warmer conditions earlier in the day and that last session, the short run and the long run both looked pretty decent ... we’re pretty satisfied with today’s running.” Verstappen, who sealed his first title at a controversial season finale in Abu Dhabi last year, had ended last week’s pre-season test at the same Sakhir track with the fastest time.
