MONACO (AP) — Ferrari had mixed fortunes in third and final practice for the Monaco Grand Prix on Saturday, with Sebastian Vettel crashing and his teammate Charles Leclerc topping the charts ahead of both Mercedes cars.

Leclerc, who is from Monaco, will look to clinch his second pole position of the season in qualifying later Saturday. In third practice, he was 0.053 seconds ahead of Valtteri Bottas and 0.213 clear of Formula One championship leader Lewis Hamilton. Red Bull's Max Verstappen was fourth fastest.

Leclerc has impressed at times in his first season with Ferrari, but Vettel is struggling with his composure once again.

Despite enjoying idyllic racing conditions under blue skies and a dry track, Vettel appeared to lock the inside left wheel and went straight into the exit barriers at Saint Devote. The four-time F1 champion swore on team radio, then clambered out of his car and walked back to the team garage with his race helmet on.
