Dani Pedrosa completed a clean sweep of Friday's practice sessions for the Czech Republic MotoGP at Brno, despite being the only rider to lap slower in the afternoon session.
The Repsol Honda star, who has won two races this year but missed another three through injury, had been almost one-second clear of the field this morning and finished FP2 with a 0.377sec lead over team-mate Casey Stoner.
Stoner finished 0.305sec ahead of Gresini Honda's Marco Simoncelli and Yamaha's reigning world champion Jorge Lorenzo a fraction slower in fourth.
Third Repsol Honda rider Andrea Dovizioso was the first rider over one-second from Pedrosa this afternoon, with Lorenzo's team-mate Ben Spies in sixth (+1.177sec).
The top six riders all repeated their morning positions.
Valentino Rossi, the top Ducati in eleventh this morning, dropped as low as 15th this afternoon, before a late charge saw the seven time MotoGP champion knock a second from his FP1 time and put his Desmosedici GP11.1 into seventh place (+1.291sec).
That came at the expense of Suzuki's Alvaro Bautista, who overturned temporary team-mate John Hopkins' slim morning advantage as the two GSV-Rs spent much of the afternoon side-by-side on the timesheets.
The pair were eventually split by rookie Cal Crutchlow, who enjoyed a second solid session on a track he knows to be the top satellite bike rider for Monster Yamaha Tech 3.
Behind tenth place Hopkins and the second best Ducati was that of satellite Aspar rider Hector Barbera (+1.666sec) with Tech 3's Colin Edwards dropping from tenth to twelfth this afternoon.
Pramac's already injured Randy de Puniet crashed without further harm at the end of the afternoon, and remained 13th, with Rossi's factory team-mate Nicky Hayden only 14th quickest in both sessions.
Hayden is still using the GP11 and isn't due to ride the GP11.1 until Monday's test, but may surely revise his strategy after such a disappointing opening day.
