Ferrari also demonstrated strong pace. Both Fernando Alonso and Felipe Massa were committed as they finished in third and fourth place. Alonso was caught out by the Sauber of Nico Hulkenberg on his quick run and narrowly missed the barrier at Rascasse. The Spaniard also brushed the wall at the final corner.
Mark Webber was fifth, while Kimi Raikkonen was sixth, ahead of team-mate Romain Grosjean, who crashed out of the session. The Frenchman was starting his qualifying simulation when he locked up into Sainte Devote and crashed into the barriers. The front left corner of his Lotus E21 was damaged, forcing him out of the session with 50 minutes remaining.
Jenson Button set the eighth fastest time, while reigning world champion Sebastian Vettel spent the opening part of the session in the garage before eventually setting the ninth quickest lap time. Paul di Resta rounded out the top 10. Friday is day off, and action conitnues with Saturday practice, followed by Qualifying.
