Championship leader Marc Marquez made history as he became the first rider to climb out of Q1 and claim pole position at the inaugural Thailand MotoGP on Saturday.
The Spaniard had to fight his way through the first qualifying session after a crash in practice, but in Q2 he stormed to a time of lmin 30.088secs for his 50th pole.
It underlined the superb form of the Honda rider, who holds a 72-point lead over Andrea Dovizioso with five races remaining as he closes on a fifth world title.
"Of course I was happy how I finished the day," Marquez, 25, told reporters, describing his morning practice session as "unlucky".
Seven-time world champion Valentino Rossi, who along with Marquez is a firm favourite among Thai fans, was 11-hundredths behind Marquez with Dovizioso third fastest.
Yamaha's Rossi described his time as a "great result" after he qualified just 18th quickest last month in Aragon, his lowest grid position since 2006.
