Casey Stoner has completed a clean sweep of Friday's MotoGP practice sessions after an opening day of changeable weather in Catalunya.
Afternoon practice saw the reverse of this morning's weather, when light rain had arrived at the midway point of FP1. Instead, FP2 began on a slowly drying track after a rain shower during the previous 125cc session.
With track conditions in-between slick and wet tyres, title leaders Stoner and Jorge Lorenzo were among those who chose to sit out the early part of the afternoon.
Stoner later took to the track - and promptly jumped 1.5sec clear of the field on only his second lap on wets, before pulling straight back into the Repsol Honda pits.
The change to slicks was signalled by Suzuki's Alvaro Bautista, who hit the front with 17 minutes remaining, but with Stoner back on track - and back on top - soon after.
Marco Simoncelli, under the spotlight this weekend after his controversial clash with Dani Pedrosa at Le Mans, briefly toppled Stoner, before the double 2011 race winner pulled out a 0.528sec advantage over the San Carlo Honda Gresini rider.
Stoner's team-mate Andrea Dovizioso made it an all-RCV top three, with 2010 Catalunya winner and reigning world champion Lorenzo in fourth place for Yamaha. Lorenzo was 0.870sec slower than Stoner and the final rider within one-second of the Australian.
Indeed, Lorenzo's team-mate Ben Spies was 1.9sec from Stoner in fifth.
The top Ducati of Valentino Rossi was a further tenth slower, with rookie cal Crutchlow once again impressing with seventh place for Monster Yamaha Tech 3.
Team-mate Colin Edwards had a far more painful session, being thrown from his M1 in the final ten minutes, leaving the Texan in obvious pain. Edwards has been taken to the Medical Centre with a suspected shoulder injury.
Behind Crutchlow, Hiroshi Aoyama (Gresini), Nicky Hayden (Ducati) and Alvaro Bautista (Suzuki) completed the top ten.
Repsol Honda's Dani Pedrosa is absent from his home grand prix due to the broken collarbone he suffered in the controversial clash with Simoncelli at Le Mans.
