Carlos Checa continued his seemingly unstoppable charge towards the 2011 World Superbike Championship by winning both races at Misano.
The Spaniard got the better of reigning champion Max Biaggi on both occasions. In race one, Checa took control in the second half of the race to lead home Biaggi with Marco Melandri a distant third.
Race two wasn't quite as straight forward with accidents for Melandri and Leon Camier necessitating a red flag. Once the race restarted, Biaggi stormed into the lead but a critical error six laps from home handed the lead to Checa, who cruised to his eighth win of the year ahead of the Italian, with Noriyuki Haga completing the podium.
After his dramatic pole position on Saturday, Tom Sykes secured his and Kawasaki's best result of the year with fourth place but he was unable to repeat that in race two after a crash dropped him to 14th.
With the front two in a class of their own all day, the entertainment in race two was provided by the battle for third between Haga and BMW Motorrad Italia's Ayrton Badovini. The Italian looked to have won the battle after passing Haga on the final lap but on the drag race to the finish line, the PATA Racing Team Aprilia had too much for the BMW S1000 RR and denied Badovini his first WSBK podium.
Leon Haslam led both races early on but will have been disappointed with the final outcome after crashing out of fourth place in race one, before racing through the pain to finish fifth in race two. Eugene Laverty also had a mixed day after finishing fifth in race one but a rare mistake in the second saw him slide off the track before recovering to 13th.
Leon Camier got the second Alitalia Aprilia into the top six before crashing at the same time as Melandri in race two, while Jonathan Rea didn't race at all due to injuries sustained earlier in the weekend.
The season will reach the halfway stage this weekend when the Championship heads to the Motorland Aragon circuit in Spain, with Carlos Checa entering his home round with a 72 point lead over Max Biaggi.
