Jorge Lorenzo has edged out Dani Pedrosa to be fastest in final practice for the San Marino MotoGP event at Misano.

Honda rider Pedrosa, 24, dominated Friday's session and was the only rider to break the one minute 35 seconds mark, but final practice was much livelier with five riders going under that time.

Championship leader Lorenzo, whose worst performance of the season was his third in Sunday's Indianapolis MotoGP, clocked 1:34.627 on his Yamaha, just 0.104 ahead of Pedrosa.

Australian Casey Stoner, the 2007 world champion, was the big improver after his disappointing session on Friday, and his Ducati whipped round the circuit in 1:34.763.

US rider Colin Edwards' Tech 3 Yamaha was fourth, and his time of 1:34.774 meant just 0.147 seconds separated the first four.

Seven-time world champion Valentino Rossi was fifth on his Yamaha in 1:34.981 and Italian Andrea Dovizioso's Honda was not far behind in 1:35.053.

Stoner's Ducati team-mate Nicky Hayden was seventh fastest in 1:35.069, just behind Dovizioso.

Young gun Hector Barbera powered his Aspar Ducati into eighth and US rider Ben Spies, who was runner-up at Indianapolis, was ninth on his Tech 3 Yamaha.

Loris Capirossi rounded out the top 10 on his Suzuki in 1:35.222.
