Jonathan Rea has moved to the head of the World Superbike timesheets at the end of a tight third free practice session which would see the top ten split by just three tenths.
With the morning FP3 session offering better track conditions than during the scorching FP1 and FP2 sessions on Friday, personal bests were quickly lowered as Tom Sykes went quickest initially, before overnight leader Marco Melandri returned to the top spot at the mid-way stage.
Indeed, save for a brief stint where Eugene Laverty moved quickest, Melandri looked set to end FP3 with the top time before PATA Honda's Rea snatched the initiative in the closing minutes.
However, the session was perhaps most notable for the closeness in the lap times with the top ten covered by less than three tenths of a second, suggesting any one of the five leading manufacturers can challenge for pole position later today.
Behind Melandri in second placed, Sylvain Guintoli and Laverty were third and fourth best – having posted the same time -, ahead of Chaz Davies, Loris Baz, Leon Haslam, Sykes, Alex Lowes and Davide Giugliano.
Outside the top ten, David Salom took over at the top of the EVO reckoning, while Claudio Corti enjoyed arguably his most positive timed session of the season with 12th best on the now full-factory MV Agusta F4.
Carrying on his positive form from Friday, Sheridan Morais was 13th fastest as the second highest EVO rider, ahead of Christian Iddon, Sylvain Barrier and a struggling Toni Elias.
Rounding out the top twenty and earning a spot in Superpole later today was Ayrton Badovini, Alessandro Andreozzi, Bryan Staring and Niccolo Canepa.
By contrast, having failed to make the cut for Superpole, Riccardo Russo, Jeremy Guarnoni, Fabien Foret, Geoff May, Gabor Rizmayer, Aaron Yates and Peter Sebestyen will start 21st down to 27th.
