Cal Crutchlow and Joan Lascorz picked up where they left off in the first World Supersport free practice session of the weekend at Monza by locking out the top two positions.

The two Assen podium winners were inseparable during practice and qualifying in the run up to the races, even if they would eventually miss out on victory to Eugene Laverty.

Nonetheless, new championship leader Crutchlow continued to show his form on the Yamaha, moving to the top of the timesheets in the latter stages of the session to edge out in initial pace setter Lascorz by a few hundredths.

Althea Honda put in a strong showing for Honda, ahead of the factory supported Ten Kate team, in third and fifth, Mark Aitchison ahead of Matthieu Lagrive, the pair being split by Crutchlow's team-mate Fabien Foret.

Surprise of the session was undoubtedly Daniel Dell'Omio, the Italian using his local knowledge to go sixth quickest on the Kuja Honda, well up on his usual position outside the top twenty.

Katsuaki Fujiwara made it a good first day for Kawasaki in seventh, with Andrew Pitt and Kenan Soguoglu a somewhat lacklustre eighth and ninth. Michele Pirro completed the top ten.

Elsewhere, Assen winner Eugene Laverty came in with the 11th quickest time for Parkalgar Honda, while Antony West was only 21st best.
