Pruett, Rojas win Grand Am season finale

Scott Pruett teamed with Memo Rojas to win the Rolex Sports Car Series' season-ending Utah 250 on Saturday at Miller Motorsports Park, the Daytona Prototype championship duo's record ninth victory of the season

Pruett, driving a BMW-powered Riley Daytona Prototype, led the final 39 laps on the 3.048-mile, 15-turn road course. The Chip Ganassi Racing with Felix Sabates entry finished 1.946 seconds ahead of 2009 race winners Alex Gurney and Jon Fogarty.

The 50-year-old Pruett finished the season with an unprecedented third Daytona Prototype title, while Rojas earned his second championship.

''It's just been unbelievable,'' Pruett said. ''It's right there at the top.''

Rojas, who qualified on the pole, led the first of 86 laps before being passed by Ricky Taylor. Rojas then turned the car over to Pruett, who beat Gurney and Taylor's co-driver, Max Angelelli, off pit road at Lap 48 and built leads of up to 8 seconds.

Angelelli was third, followed by Mark Wilkins and Ryan Dalziel.

Stevenson Motorsports teammates Robin Liddell and Jan Magnussen finished 1-2 in the race's production-based GT class (13th and 14th overall). Liddell edged Magnussen by 0.188 seconds for the first victory by a Chevrolet Camaro in the Rolex Sports Car Series. Emil Assentato and Jeff Segal finished sixth in class and 18th overall in their Mazda RX-8 to share the 2010 GT class championship.
