Sergio Perez edged out Ferrari's Charles Leclerc to put himself back on top in Saturday's final Formula One practice session for the Azerbaijan Grand Prix. The Mexican, who headed into the weekend with his sights set on following up his Monaco victory by becoming the first repeat winner at the Baku city track, lapped the six-km, barrier-lined layout in one minute 43.170 seconds. That was good enough to eclipse Leclerc, who is looking to bounce back from the double disappointment of losing out on victory in Spain and Monaco, by 0.070 seconds.
