Noriyuki Haga and Troy Corser took a win each in Sunday’s ninth round of the World Superbike championship at Laguna Seca, USA.

Haga won the opening race but only after Colin Edwards (Castrol Honda-Michelin) powered off the startline to take an early lead. Haga took over at the front on lap four of 28 and eventually won by 2.6s from Edwards.

Ben Bostrom (Team Ducati NCR-Michelin) narrowly missed out on third place which went to Troy Corser after a thrilling last lap with the dicing pair when they exchanged places three times in the last two corners.

Corser took 17 laps to hit the front of race two before easing away to win by 7.7 seconds from Haga. The Japanese Yamaha rider passed Bostrom on the last corner of the last lap to grab second place. Behind third placed Bostrom came Edwards, the American Honda rider completing his best ever day at the Californian track in 10 years of racing there.

Edwards commented: “It’s always a tough weekend at Laguna Seca but the next two rounds, at Brands Hatch and Assen really suit the Castrol Honda and the Michelins so I’m looking for wins there.”

Pole position rider Troy Bayliss (Ducati Infostrada-Michelin) crashed out of the first race while third, escaping injury and bounced back to take seventh place in race two.

Aaron Slight (Castrol Honda-Michelin) took eighth and ninth places while Juan Borja (Ducati Infostrada-Michelin) took ninth in the opening race but crashed out of race two, escaping injury.

Edwards continues to lead the championship, now by 18 points from Corser with four rounds, eight races remaining. Most of the World Superbike factory riders now head for Japan and the annual Suzuka 8 hours race on July 30.
