Alex de Angelis has shown his fourth place on the Indianapolis grid is no fluke by surprisingly leading the warm-up.

The rider from San Marino left it to the very last lap to shoot to the top with his Gresini Honda thanks to an impressive 1m40.446s lap that ruined what had been Dani Pedrosa's perfect weekend.

The factory Honda rider, who dominated qualifying after also topping all practice sessions, was leading the 20-minute warm-up when he took the chequered flag, but that was before being pushed down to second by de Angelis.

The Spaniard thus ended up 0.043sec behind, but his main rivals, namely Yamaha riders Jorge Lorenzo and Valentino Rossi, were still behind.

The two, who will join Pedrosa on the front row later today, ended the session respectively in third and fourth place but, most importantly, their gaps to the triple world champion have shrunk to less than three tenths of a second.

Toni Elias, in the second Gresini Honda, was fifth fastest, eight tenths behind his team-mate, but ahead of home favourites Nicky Hayden (Ducati) and Colin Edwards (Tech 3 Yamaha).

Italians Marco Melandri (Hayate Kawasaki), Andrea Dovizioso (Honda), and Loris Capirossi (Suzuki) round up the top ten.

Pramac Ducati's Niccolo Canepa crashed in the dying seconds of the session while stand-in team-mate Aleix Espargaro managed to end up 15th after beating Suzuki's Chris Vermeulen and Scot Honda's Gabor Talmacsi.
