BAKU (Reuters) - Valtteri Bottas topped the final Azerbaijan Grand Prix practice and team mate Lewis Hamilton finished third as Mercedes heaped pressure on Ferrari's Formula One championship leader Sebastian Vettel, who retired early with hydraulic problems on Saturday.
Bottas, on soft tyres, had been the early pacesetter, but a mistake on Turn Two saw Hamilton usurp him as practice leader, before the Finn bounced back and finished top of the classification with a time of 1.42.742. Ferrari's Kimi Raikkonen was second.
