When Antonio Giovinazzi smacked a barrier on the exit of the Fagnes chicane, forcing George Russell to crash in avoidance, the Italian had no way of knowing he’d inadvertently triggered a much-needed dose of tension into a less than thrilling Belgian Grand Prix on Sunday. The accident and its subsequent safety car interruption ensured the majority of the field headed for their single pit stops earlier than planned at Spa-Francorchamps. Would the enforced long stints lead to the kind of late-race Pirelli tyre failures that enlivened the British GP? That was certainly Lewis Hamilton’s fear. As it turned out, he needn’t have worried. His fifth win out of seven races was already in the bag. In truth, it had been from the moment he headed out to qualify on Saturday afternoon.
