San Francisco Frontiers - Leclerc fastest in Monaco practice as Hamilton crashes

Leclerc, who last year became the first Monegasque winner of his home event in the Formula One era, clocked a best lap of one minute and 10.953 seconds –- the only driver to dip below one minute and 11 seconds –- to beat Max Verstappen by 0.280 seconds.

Ferrari and Leclerc are hoping for a repeat of their emotional 2024 triumph, but their mood was spoiled when the Monegasque's teammate Hamilton crashed on entry to Casino Square to end the session with a red flag.

He was unhurt, but it was an uncharacteristic setback for the Briton who had looked fast and strong.

Hamilton was running in the turbulent air behind Kimi Antonelli of Mercedes and Esteban Ocon of Haas when he lost downforce and hit the barriers.

Lando Norris was third fastest for McLaren ahead of team-mate and championship leader Oscar Piastri, Hamilton and Williams' Alex Albon.

Liam Lawson of Racing Bull was an impressive seventh ahead of Carlos Sainz in the second Williams, Yuki Tsunoda of Red Bull and Antonelli.

After a slow start the session burst into life by the halfway mark with Hamilton, Norris and Leclerc trading fastest laps before Verstappen took control.

To the delight of the local audience, Leclerc regained top spot in 1:11.179 on his softs and then went even quicker to move two-tenths clear before the session stopped for a red flag when Hamilton smacked the barriers at Massenet, damaging his right front and rear wheels.

He was unhurt and climbed clear.

"Sorry guys, I've hit the wall," said Hamilton, left hoping his car could be repaired in time for qualifying later Saturday.
