Scott Pruett beat Alex Gurney in a sprint to the checkered flag to win Thursday's Brumos Porsche 250 at Daytona International Speedway in the closest finish in the history of the Grand-Am Rolex Sports Car Series.

It was the fifth -- and most dramatic -- victory of 2008 for Pruett and Memo Rojas in the No. 01 Lexus Riley. The winners of the 2008 season-opening Rolex 24 At Daytona, Pruett and Rojas extended their Daytona Prototype championship lead to 40 points after their seventh podium finish of the season.

The final margin of victory was 0.081 seconds, bettering the mark Pruett and Luis Diaz set in 2005 at California Speedway when they edged Wayne Taylor and Max Angelelli by .096 seconds.

Gurney and Fogarty were aiming for their second consecutive triumph in the No. 99 car. Gurney passed Pruett for the lead with 22 laps remaining, and led through the final 100 yards of the race.

The 70-lap, 250-mile race ended with a one-lap sprint to the finish following the fifth and final caution when Jeff Segal flipped the second-place No. 69 Mazda RX-8 after an altercation with a Daytona Prototype. Nick Ham and Sylvain Tremblay went on to win their third consecutive race at Daytona.

Ricardo Zonta and Nic Jonsson matched their best showing of the season by finishing third in the No. 76 Pontiac Lola. Fourth came down by a side-by-side battle between Brumos Racing teammates, with Joao Barbosa passing and holding off Darren Law.

It marked the best finish of the season for the No. 59 Porsche Riley of Law and JC France, while Law and David Donohue recorded the fourth consecutive top-five finish in the No. 58 Porsche Riley.

Tremblay bested Bryce Miller by 1.83 seconds to win in GT. Miller passed Robin Liddell at the line for his and co-driver Dirk Werner's best finish of the season.

Four cautions for 16 laps slowed the race's average speed to 102.690 mph.

The Rolex Series returns to action July 19 for the Porsche 250 Presented By Bradley Arant at Barber Motorsports Park near Birmingham, Ala.
