MONACO (Reuters) - Lewis Hamilton sounded encouraged by his upgraded Mercedes after the first day of Monaco Grand Prix practice on Friday, even though the principality's tight and twisting streets were no place for a meaningful assessment.

The seven times Formula One champion, who has not won a race since 2021, was third fastest in the first session and sixth in the second.
