Piastri on top in Miami Grand Prix practice

MIAMI - Formula One championship leader Oscar Piastri was fastest in sole practice for the Miami Grand Prix on May 2, while McLaren teammate Lando Norris had to pit and jettison tools left in his car.

The Australian, chasing a third win in a row on May 4, lapped on the quickest soft tyres with a best time one minute 27.128 seconds with Ferraris Charles Leclerc next best but 0.356 slower.

Red Bulls reigning champion Max Verstappen, arriving in Miami after celebrating the birth of his first child with partner Kelly Piquet, was third quickest and 0.430 off the leading pace.

The Miami round is a sprint weekend, with qualifying for the May 3 100km race later on May 2 instead of a second practice session.

Norris, 2024s Miami winner who lost the championship lead to Piastri in Saudi Arabia two weeks ago, was only 12th on the timesheets after red flags prevented him completing a lap on soft tyres.

He had to pit earlier after he found tools, including a torch, left in the cockpit when he took to the track for his first lap.

Stewards said they were investigating the team for releasing the car in an apparently unsafe condition, with the risk of a fine.

The session was stopped with four minutes remaining after Haas rookie Ollie Bearman hit the wall at Turn 12, before some drivers had completed quick laps on the soft tyres.

Norris and Haas Esteban Ocon had earlier had a near-miss when the McLaren came up fast on the Frenchman going slow on the racing line at the end of the straight. That incident was also being investigated.

Williams Carlos Sainz was fourth with teammate Alex Albon fifth and Racing Bulls rookie Isack Hadjar sixth.
