Hector Barbera kept up the pace he set earlier today in free practice to claim the top slot on the timesheets in the final 250cc qualifying session.
Barbera fended off Simoncelli in the final qualifying session today, but it was certainly close. Simoncelli was just 0.077 of a second slower than his rival Hector Barbera.
Spanish rider Aleix Espargaro took third place, giving him his first ever front row start in tomorrow's race.
Yuki Takahashi claimed 4th place for JiR Team Scot 250 ahead of his countryman Hiroshi Aoyama who took 5th position.
Sixth place went to Thomas Luthi of the Emmi Caffe Latte team, closely followed by Spaniards Julian Simon and Hector Faubel.
That left Mattia Pasini of the Polaris World team and Mika Kallio on his Red Bull KTM 250 to round out the top ten.
