Iannone claims career first MotoGP pole in Mugello

Iannone trailed Yamaha's Jorge Lorenzo after the opening runs and his hot lap appeared to have drifted away as he completed the third of four sectors.

But Iannone latched onto the back of Lorenzo's Yamaha and took advantage of the slipstream along Mugello's long straight to take top spot with a 1:46.489 and demote the Spaniard to second position.

Andrea Dovizioso claimed third place to ensure two Ducati riders will start from the front row of the grid.

Cal Crutchlow was fourth while Aleix Espargaró escaped from Q1 and promptly set the fifth quickest time for Suzuki.

Ducati wildcard rider Michele Pirro will start from sixth place, ahead of Honda's Dani Pedrosa and Championship leader Valentino Rossi.

Maverick Viñales was ninth for Suzuki while Pol Espargaró, Bradley Smith and Yonny Hernández completed the Q2 runners as Márquez struggled.

Márquez failed to automatically qualify into Q2 by 0.007s in the final practice session, meaning that he had to participate in Q1 for the first time in two years.

Márquez initially posted the second quickest lap in the session but was demoted to third by Hernández and missed out on a slot in Q2.

That leaves Márquez in 13th place on the grid, ahead of Danilo Petrucci and Héctor Barberá.

Stefan Bradl was 16th, pursued by Scott Redding, Loris Baz and 2006 champion Nicky Hayden.

Karel Abraham recovered from a crash in the morning session to go 20th, ahead of Álvaro Bautista and Mike di Meglio.

The grid will be completed by Jack Miller, Eugene Laverty, Alex de Angelis and Marco Melandri.
