It was not until the thirteenth race of the season, the inaugural Aragon Grand Prix, that Stoner achieved his first victory. His victory in Aragon started a run of three victories in four races, as he also won the delayed Japanese Grand Prix, and won for the fourth consecutive year at Phillip Island. He eventually finished fourth in the riders' championship once again. With Rossi having fallen out of favour with Yamaha following Lorenzo's championship-winning season and Honda no longer willing to play second-fiddle to another Japanese manufacturer, an intense game of musical-chairs ensued in the MotoGP paddock that saw several of the top riders switch teams, Stoner among them. For 2011, Stoner joined Honda Racing Corporation after four years at Ducati Corse, where he was replaced by Valentino Rossi.
