Cal Crutchlow made it three different leaders from three practice sessions, during Saturday morning at the Czech Republic MotoGP.
The Monster Yamaha Tech 3 star, who claimed his first podium at Brno last year, looked unhappy with the handling of his M1 earlier in the session, but re-grouped to move to the top of the timesheets by 0.166s from Jorge Lorenzo.
Crutchlow's best lap time of 1m 56.156s, the best of the weekend by 0.344s, was set on his penultimate lap.
As on Friday, Factory Yamaha star Lorenzo led most of the 45-minute session, setting his best time on lap six.
Although Crutchlow moved ahead right at the end, Lorenzo again set an ominous pace. His 16 fast laps were split into just two runs - with all but one of his lap times below 1m 57s (Crutchlow set three sub-1m 57s laps).
Only Repsol Honda's rookie title leader Marc Marquez was able to run a comparable pace to Lorenzo this morning, setting ten 1m 56s on his way to a weekend best third place with a fastest lap just 0.210s from Crutchlow.
Lorenzo's team-mate Valentino Rossi
made a similar time gain on his way to fourth place, 0.330s from Crutchlow (five sub 1m 57s lap), while Stefan Bradl and Dani Pedrosa
dropped to fifth and sixth on combined times after failing to improve this morning.
Friday pace setter Bradl, who had warned there was plenty of work still to do, was just eighth (+0.899s) in FP3, with Pedrosa sixth (+0.486s) for Repsol Honda.
The top ten riders on combined times after FP3 receive direct access to the second and final part of this afternoon's qualifying session.
The other riders already through to Q2 will be Alvaro Bautista (Gresini Honda), Bradley Smith (Tech 3 Yamaha), plus factory Ducati riders Nicky Hayden
and Andrea Dovizioso.
Andrea Iannone misses out in eleventh - the injured Italian falling while following Rossi closely in his quest to break into the top ten. Pramac Ducati stand-in team-mate Michele Pirro will also join the CRTs in the Q1 session.Free Practice 3:
