Baku, August 3, AZERTAC Lewis Hamilton limped to a record seventh British Grand Prix victory with his heart in mouth and a prayer on his lips after a dramatic last-lap puncture turned his Mercedes into a three-wheeler on Sunday, according to Reuters. In an astonishing end to a race he had dominated from pole position, the six-times world champion nursed his stricken Mercedes across the line to stretch his Formula One world championship lead to 30 points.Red Bull’s Max Verstappen finished second, but could have won had he not pitted for fresh tyres in a successful late bid to score an extra point for the fastest lap, assuming victory was out of reach.Ferrari’s Charles Leclerc was third, another surprise for a team struggling for performance.Hamilton’s team mate and closest rival Valtteri Bottas failed to score after also suffering a late puncture and finishing 11th, despite a one-two finish for the pair having looked a nailed-on certainty until late in the race.The victory was the 87th of Hamilton’s F1 career — leaving him four short of Ferrari great Michael Schumacher’s all-time record of 91 — and his third in a row. It was also probably his greatest escape.
