No. 16 racing team of David Donahue, Darren Law, Buddy Rice and Antonio Garcia gives Brumos Racing first victory in 2009 Rolex 24 hours at Daytona

DAYTONA BEACH -- David Donohue passed Juan Pablo Montoya with 39 minutes remaining and held on to win the 47th Rolex 24 At Daytona - on the 40th anniversary of his father, Mark Donohue's, victory in the 1969 event, according to a post-race Rolex press release.

Donohue joined Darren Law, Buddy Rice and Antonio Garcia to give Brumos Racing its first Grand-Am Rolex Sports Car Series presented by Crown Royal Cask No. 16 victory since 2003, denying TELMEX/Target Chip Ganassi Racing with Felix Sabates its fourth consecutive victory in America's premier sports car event.

"These guys have put a lot of effort into this," Donohue said. "I'm glad to be able to carry the flag."

Montoya pressured Donohue throughout the final 39 minutes, but the No. 01 Lexus Riley could not overcome the strong of the Brumos Porsche on the Daytona banking.

Joao Barbosa finished third in the No. 59 Brumos Racing Porsche Riley shared by JC France, Hurley Haywood and Terry Borcheller, while Max Angelelli took fourth in the No. 10 SunTrust Racing Ford Dallara co-driven by Wayne Taylor, Pedro Lamy and Brian Frisselle.

The record-breaking event had the closest margin of victory, most finishers on the lead lap and most cautions. The top four finishers covered 735 laps -- most in the Daytona Prototype era.

The GT race came down to a one-two finish for TRG Porsche, with Andy Lally and Justin Marks joined by Jorg Bergmeister, Patrick Long and RJ Valentine in the winning No. 67 Porsche GT3. Second, one lap behind, was the TRG No. 66 of Spencer Pumpelly, Tim George Jr., Richard Leitz and Emmanuel Collard.
