Scott Pruett and Memo Rojas scored their second victory in three years at Homestead-Miami Speedway in the #01 TELMEX Chip Ganassi Racing BMW Riley on Saturday, when Pruett held off the charging #59 Brumos Porsche Riley of David Donohue and pole winner Darren Law by 0.255 seconds.

"I sure didn't want to see that last caution, but I was happy for the fans," Pruett said after scoring his 23rd Rolex Series overall victory. "This is tough competition. You never know what's going to happen until the checkered flag falls. It was pretty exciting in my seat, that's for sure."

Donohue was able to pull up to the back of Pruett several times in the closing laps, but was unable to get by. Pruett managed to weave through GT traffic in the infield on the final lap, and maintained the lead through the superspeedway banking.

The race began in controversial fashion, when Rojas's Riley and the #6 Michael Shank Racing Riley of Brian Frisselle had a coming together at the first corner of the first lap that left the MSR car off the track and its driver fuming; “I’m really disappointed in the officials for not penalizing him, if that’s not a racing incident, then I guess i can do that in the next race,” said Frisselle to the SPEED TV crew during the live broadcast. “It’s really a shame because Michael Shank Racing once again did a great job, we had the car to win today.”

Alex Gurney finished third in the #99 GAINSCO/Bob Stallings Racing Chevrolet Riley started by Jon Fogarty. Burt Frisselle finished fourth in AIM Autosport's #61 Ford Riley, followed by Ryan Dalziel in the debut of the #8 Starworks BMW Riley started by Mike Forest, the leading Daytona Prototype Pro-Am driver in the event.

“To finish third and come away second in the team points is a testament to how good the team is,” said Fogarty.  “For our relative pace in the race, we only had the 10th fastest race lap overall, but strategy wise we did everything right.  We didn’t make any mistakes and we stayed up toward the front and maintained our track position.”

“It was definitely a good day points wise but we had the usual struggle here at Homestead,” added Gurney.  “I feel like we have never really got the races right here. We were really light on downforce today and just struggled for grip.  It was a tough day but we held on for third and I think that is as good as we were going to do today.”

A turning point came on Lap 81 of the two-hour, 45-minute race. The cockpit of the #30 Racers Edge Motorsports Mazda RX-8 exploded into flames, and Jordan Taylor came to a stop in the middle of pit road. The blaze was quickly extinguished and the race remained under green, but Taylor's car was stopped in the middle of the pit lane when Law pitted in the race-leading #59 Brumos Riley.

"There was a car on fire, there were people on pit lane, and I almost came to a stop," Law explained. "I didn't want to hit anybody. It's unfortunate, because I lost all of the gap I had gained. Up until then, I was feeling really, really good."

Taylor was uninjured in the incident, but the Mazda started by Todd Lamb was eliminated after having a strong run. "It wasn't as big a fire as it looked," Taylor said. "It ended up being some of the insulation in the exhaust catching fire."

Donohue replaced Law on the ensuing pit stop. Pruett took the lead in the exchange and led the rest of the way.

Pruett and Rojas averaged 107.196 mph, completing 129 laps on the 2.3-mile circuit, and took the points lead by six (67-61) over Ryan Dalziel. The race remained caution-free until lap 115, for debris in Turns 4 and 8. Law led a race-high 71 laps, followed by Pruett with 48. Other race leaders included Fogarty, who led the opening six laps, and Ryan Hunter-Reay, who led two laps in the #95 Level 5 Motorsports BMW Riley.

Rolex 24 winners Terry Borcheller and Dalziel each led one lap in different cars. Borcheller was running in contention in the Daytona-winning #9 Action Express Racing Porsche Riley. Joao Barbosa, the 2009 Homestead winner seeking his third consecutive Rolex Series victory, went behind the wall early in his shift to replace the heat exchanger.

In GT, Jeff Segal passed SpeedSource teammate Sylvain Tremblay on the race's lone restart with 13 minutes remaining and went on to win in the #69 FXDD Mazda RX-8. It was the third triumph in the last six races for Segal and Emil Assentato.

Tremblay, who led 27 laps, fell back to fourth in the closing laps, but he and Jonathan Bomarito maintained the points lead by three (63-60) over Robin Liddell and Andrew Davis, who finished second in the #57 Stevenson Automotive Camaro;  “We were really at a disadvantage to the quickest Mazdas and the BMW," admitted Liddell. "On new tires I could just about stay with the #69 winning Mazda and the BMW, but after a few laps they were gone. Overall though the car performed very well throughout the weekend; we had no problems to speak of so congratulations to the guys again for preparing an excellent car for us to drive. Again, thanks to Johnny and Susan for putting together a fine team. It was a difficult day for them so being able to get second in GT hopefully helped to make amends!"

Finishing third were Leh Keen and James Gue in the #41 Dempsey Racing Mazda RX-8.

Bill Auberlen and Joey Hand finished a solid fifth in the #94 Turner Motorsport BMW M6. The car ran only three laps in practice prior to the race and did not qualify due to problems with the power steering. Team owner Will Turner installed a power steering unit from a Daytona Prototype prior to the race, and Auberlen and Hand ran in contention throughout the event, with Hand leading four laps.

Paul Edwards started from the GT pole in the Banner Racing #07 Mobil 1 Corvette and led the opening 31 laps before turning the car over to motorcycle legend Scott Russell. Edwards returned to the car for the closing shift, finishing sixth - one position ahead of Patrick Dempsey and Joe Foster in the #40 Dempsey Racing Mazda RX-8.

Ted Ballou and Andy Lally had the highest-finishing Porsche, placing eighth in the #66 AXA Porsche GT3. “We just couldn’t run the pace that the tube-frame cars could this weekend, it’s extremely frustrating to race like this,” said Lally. “When I got in the car I did everything I could to keep us on the lead lap, but after only a few laps the rear tires just burned off, and we were just doing what we could to hold on.”

The next race for the Grand-Am Rolex Series will be the Porsche 250 at Barber Motorsports Park in Birmingham, Alabama on April 10th.
