Lewis Hamilton pipped Valtteri Bottas as Mercedes dominated second practice at the Monaco Grand Prix.
The world champion was just 0.081 seconds ahead of the Finn.
Red Bull’s Max Verstappen, second behind Hamilton in first practice, missed much of the second as a result of a water leak and ended up sixth.
Ferrari’s Sebastian Vettel was third fastest – but a massive 0.763secs off the pace. Team-mate Charles Leclerc was 10th, struggling with car set-up.
Vettel also had a near-miss at Turn One, when he locked a wheel on entry and just managed to get the car stopped before hitting the barriers.
