Casey Stoner set the fastest ever Indianapolis MotoGP lap during Saturday morning's final practice session for round twelve of the 2011 season.
After criticism of the slippery new asphalt - laid between turns 5 to 16 - on Friday morning, track conditions have become significantly quicker since.
The best lap time dropped by 2.5sec by the end of Friday and Stoner lowered it by a further 1.186sec in final practice, as he beat the previous best two-wheel lap - by Dani Pedrosa, during qualifying in 2009 - by 0.192sec.
As on Friday afternoon, home star Ben Spies was once again closest to championship leader Stoner, Spies' factory Yamaha lapping 0.132sec behind the Repsol Honda.
Spies - runner-up from pole last year - was the only non-RC212V in the top five, with Dani Pedrosa (+0.358sec), Marco Simoncelli (+0.763sec) and Andrea Dovizioso (+0.788sec) behind him.
Then came the satellite Yamaha of Texan Colin Edwards (+0.900sec) while reigning world champion Jorge Lorenzo could only manage seventh, and over one-second off the pace, on the second factory M1.
Valentino Rossi was eighth (+1.160sec) and the leading Ducati rider, with Pramac's Randy de Puniet ninth and Suzuki's Alvaro Bautista tenth.
Rossi's American team-mate Nicky Hayden could only manage eleventh, while rookie Cal Crutchlow made progress to claim twelfth for Tech 3.
Gresini's Hiroshi Aoyama completed a 17-rider field covered by 2.351sec.
Qualifying takes place this afternoon.
