DAYTONA BEACH, Fla. --- Kyle Busch received intravenous fluids Saturday after his driving stint in the Grand-Am race at Daytona International Speedway, then retreated to his motorhome to rest before NASCAR's 400-mile Sprint Cup event.

Busch, the defending race winner of NASCAR's Coke Zero 400, drove 70 minutes in his sports car series debut. He split the Chip Ganassi-owned ride with fellow NASCAR driver Scott Speed .

"Very, very, hot in those cars," Busch said. "Just the biggest thing was to get some fluids back in me since I know I lost a ton of fluids. The faster you can get to the medical center after getting out of the car, the faster I could get taken care of and get some rest before tonight's race."

A spokesman for Busch said the driver received the IV as a precautionary measure. Speed also received an IV following the race.

Busch and Speed teamed to finish 10th in the race.

MARTIN'S MISERY: Mark Martin has never enjoyed Daytona Inter-national, not even when he nearly won the 2008 Daytona 500.

Martin, who despises restrictor-plate racing that keeps cars bunched together and often leads to big wrecks, now has more reason to hate the famed track.

Martin was involved in the first accident of the Coke Zero 400 on Saturday night. Former teammate Matt Kenseth tapped the rear off Martin's car coming off turn two on lap 13 and sent Martin spinning across the track.

Martin was taken to the infield care center, treated and released.

NEW CHALLENGE : Vince Carter 's off-the-court driving skills don't even compare to his on-the-court driving skills.

Carter spent several hours driving a car back and forth in his driveway one night this week, trying to perfect his stick-shift prowess before serving as the honorary pace-car driver for Saturday's Coke Zero 400.

The eight-time NBA All-Star, the Orlando Magic's biggest off-season addition, said he had never driven a car with a stick shift before this week.

So his first few attempts left a lot to be desired, so he went to the practice court -- his driveway at home.

Carter, a Daytona Beach native, accepted the invitation to drive the pace car before the Magic acquired him in a draft-day trade with the New Jersey Nets last week.

"So much has happened for me in the last week," Carter said.

INDYCAR SERIES: In Watkins Glen, N.Y., Ryan Briscoe won the pole for the Camping World Grand Prix.

Briscoe won his second consecutive pole on the 11-curve, 3.4-mile road course with a fast time of 1 minute, 28.5970 seconds in the Firestone Fast Six Shootout, breaking the track record held by Helio Castroneves by more than a second.

Justin Wilson finished second ahead of Scott Dixon , Mario Moraes and Graham Rahal.

Dario Franchitti crashed entering the final turn during the shootout and finished sixth, just ahead of rookie Mike Conway and Danica Patrick.

Castroneves failed to make it to the final round and will start Sunday's race in 14th.
