Suzi Perry presents as coverage resumes with the San Marino Grand Prix at Misano. Italian Valentino Rossi looks to extend his championship lead over Casey Stoner with a third successive victory. Stoner gifted Rossi his 67th MotoGP win last time out, crashing out whilst leading his Italian rival in the Czech Republic. With just six races remaining, Australian Stoner simply cannot afford another slip if he is to retain his crown. Meanwhile, Britain's James Toseland is still looking for his first podium finish in his maiden season in MotoGP.
