Daytona Prototype points leader Scott Pruett will lead a record field of 38 cars to Mexico City's famed Autodromo Hermanos Rodriguez this weekend for Saturday's Grand-Am Rolex Sports Car Series Mexico City 400k.

Pruett, the 2004 Daytona Prototype co-champion, leads the 2007 Daytona Prototype driver standings by virtue of his victory in the season-opening Rolex 24 At Daytona alongside co-drivers Juan Pablo Montoya and Mexican rising star Salvador Duran. With Montoya focusing on NASCAR competition and Duran involved in various other forms of international motorsport and not entered to compete this weekend, Pruett essentially stands alone atop the points table.

The Rolex 24 victory was the 13th overall triumph in Rolex Series competition for the Californian, tying him with James Weaver for most career overall victories. This weekend, Pruett will be joined in the #01 TELMEX Chip Ganassi Racing Lexus Riley by his full-time co-driver for the remainder of the season, Mexican racer Memo Rojas. Last year in Mexico City, Pruett started from the pole position and combined with then-co-driver Luis Diaz to lead every lap in the race en route to a wildly popular victory.

A repeat this weekend, however, is anything but a certainty for Pruett, Rojas and the Ganassi team. Leading an extremely talented list of drivers with the potential to dethrone the #01 team are Italian racing standout Max Angelelli and Danish speedster Jan Magnussen in the #10 SunTrust Pontiac Riley. Angelelli and Magnussen combined with team owner Wayne Taylor and NASCAR superstar Jeff Gordon to finish third in the Rolex 24 despite battling various mechanical issues for a goodly amount of the twice-around-the-clock event. Absent mechanical problems this weekend, Angelelli and Magnussen would be tough to beat.

Rolex 24 runners-up Patrick Carpentier and Milka Duno also cannot be overlooked in the #11 CITGO/SAMAX Pontiac Riley. While Carpentier is considered a Rolex Series "rookie," the Canadian is no stranger to Autodromo Hermanos Rodriguez with three Champ Car starts at the historic circuit. He and Duno - a three-time winner in Rolex Series competition - could also prove to be a formidable combination.

On the heels of a fourth-place performance in the Rolex 24 and armed with a potent Porsche Riley combination, JC France and sports car racing legend Hurley Haywood also head south of the border looking to continue their momentum in the #59 Brumos Racing machine. Haywood is in his final season of full-time Rolex Series competition, while France was involved in a memorable altercation following an on-track incident with driver Chris Bingham in last year's visit to Mexico City. That being the case, a strong performance this weekend would be popular for several reasons.

The upstart AIM Autosport team - with youngsters Mark Wilkins and Brian Frisselle sharing the #61 Exchange Traded Gold Lexus Riley - also looks to build more momentum following a fifth-place performance in the Rolex 24. Last year, Frisselle turned in a career-best second-place qualifying performance at Mexico City, proving he knows the quick way around the 2.5-mile road course. That could bode well for the #61 team, which is competing in just its third Rolex Series event this weekend.

While a top-five finish in the Rolex 24 was a great way to start the season for those teams mentioned previously, there are several other talented combinations that will undoubtedly play a role in the outcome of the Mexico City 400k. Certainly, one cannot look past Americans Jon Fogarty and Alex Gurney in the #99 GAINSCO/Bob Stallings Racing Pontiac Riley.

Gurney started the Rolex 24 from the pole position, proving yet again that he and the #99 team are among the quickest in the Rolex Series. However, Gurney and Fogarty head to Mexico still looking for their first career Rolex Series victory after coming tantalizingly close on several occasions last season.

Another pairing that should be plenty fast this weekend and throughout the season is Patrick Long and 2006 Daytona Prototype champion J?rg Bergmeister in the #23 Ruby Tuesday Championship Racing Team Porsche Crawford. Like many others in the field, Long and Bergmeister will undoubtedly be front-runners if their #23 machine avoids mechanical pitfalls.

After picking up his first career Rolex Series podium result with a second-place run last year in Mexico City, 18-year-old Colin Braun and his new-for-2007 co-driver Max Papis will also be contenders in the #75 Krohn Racing Pontiac Riley. Braun's runner-up result in Mexico last year set the tone for a wildly successful season that yielded him a pair of victories, while Papis is always strong behind the wheel of a Daytona Prototype as evidenced by the 2004 title he shared with Pruett.

Mexico-born Memo Gidley, the winner of the inaugural Rolex Series event at Autodromo Hermanos Rodriguez, returns this weekend looking to recapture that glory alongside co-driver Jorge Goeters - who started the first-ever NASCAR Busch Series event in Mexico from the pole position - in the #77 Kodak/Star Motorsports Ford Doran for Feeds The Need/Doran Racing. It is the third different chassis and engine combination for Gidley in three events at Mexico City, as his victory in 2005 came in a BMW-powered Riley chassis and he co-drove a Ford Crawford in the event last year.

Finlay Motorsports, the team for which Gidley drove the past two seasons, also returns to the site of its first Rolex Series triumph this weekend with Canadian Michael Valiante and team owner Rob Finlay co-driving the #19 Z-Line/Mission Residence/Make-A-Wish Ford Crawford. Now in their second full season as co-drivers, Valiante and Finlay have the benefit of experience, which could translate to success this weekend.

Last year, both cars from Michael Shank Racing were extremely quick in pre-event practice sessions before crashes put the team behind the eight ball. If the team avoids a similar fate this weekend, look for both the #60 Lexus Riley in the hands of Oswaldo Negri Jr. and Mark Patterson and the #6 Lexus Riley with co-drivers Ian James and Henri Zogaib to be front-runners.

Zogaib, Patterson and Finlay head to Mexico looking to make up ground to owner/driver Tracy Krohn in the race for the 2007 Jim Trueman Award for the top sportsman driver in Daytona Prototypes. Krohn leads with 831 points, followed by Patterson with 732 points, Finlay with 416 and Zogaib with 271. Krohn will co-drive the #76 Krohn Racing Pontiac Riley this weekend with Nic J?nsson.

Completing the impressive driver lineups in Daytona Prototypes are Jim Matthews and Marc Goossens in the #91 Riley-Matthews Motorsports Pontiac Riley, David Donohue and Darren Law in the #58 Red Bull/Brumos Racing Porsche Riley, Christian Fittipaldi, Harrison Brix and Eddie Cheever Jr. in the #39 Crown Royal Special Reserve/Cheever Racing Porsche Fabcar, Bill Auberlen and Matthew Alhadeff in the #05 Luggage Express Team Sigalsport BMW Riley and Shane Lewis and Randy Ruhlman in the #3 Preformed Line Products/Southard Motorsports Lexus Riley.

The GT class will feature its largest Mexico City field to date with 20 cars on the entry list. Leading the way are class points co-leaders Carlos de Quesada and Jean-Francois Dumoulin in the Rolex 24 at Daytona class-winning #22 Gatorade/TodayMD.com Porsche GT3 entered by Alegra Motorsports.

If they are to retain their lead in the driver standings following the Mexico City 400k, they will have to overcome a strong challenge from several perennial front-runners in the class. Topping that list are #07 Banner Engineering Pontiac GXP.R co-drivers Paul Edwards and Kelly Collins. Edwards has won the GT class in both previous Rolex Series events in Mexico City and shared the class victory last year with Collins. The #07 duo is joined by Banner Racing teammates Leighton Reese and Tim Lewis Jr. in the team's #06 Banner Engineering Pontiac GXP.R.

While Edwards and Collins look for a repeat, so too does the TRG team for whom Edwards drove to victory in each of the past two Rolex Series events south of the border. TRG will bring a pair of Porsche GT3s to Mexico City, with defending GT co-champion Andy Lally slated to share the #66 CRG/Maxter/Rotax/MBA/NFP/F1 Air Porsche with RJ Valentine and Spencer Pumpelly entered in the #67 Cohen Financial Porsche alongside Scott Schroeder.

Another pair of strong Porsches has been entered by Tafel Racing. Nathan Swartzbaugh and Andrew Davis will co-drive the team's #72 North South Machinery/ANCA/Dunkel Bros/Tornos Porsche GT3, with lightning-fast German Wolf Henzler and New York teenager Eric Lux slated for the #74 Rembrandt Charms Porsche GT3.

The Porsche contingent is further bolstered by Patrick Huisman and George Biskup in the #81 EMC Mechanical/Gamewell Mechanical Porsche GT3 from Synergy Racing, the two-car Farnbacher Loles Motorsports line-up of Dominik Farnbacher and Leh Keen in the team's #85 Shoes for Crews/Recaro Porsche GT3 and Bryce Miller and Dirk Werner in the #87 Marquis Jet/Recaro Porsche GT3, and the #17 Minestar Solutions/Tim Horton's Porsche GT3 of Greg Wilkins and Dave Lacey with Doncaster Racing.

Adding to a manufacturer-rich GT class are Champ Car veteran Alex Tagliani and car owner Tom Nastasi in the #15 USG Sheetrock/Guardian Insulation Ford Mustang Cobra GT for Blackforest Motorsports; two Mazda RX-8s from SpeedSource with drivers Sylvain Tremblay and Nick Ham sharing the team's #70 Mazda/Mazdaspeed entry and Emil Assentato and Nick Longhi in the #69 FXDD RX-8; three Chevrolet Corvettes, including Joe Sahlen and Will Nonnamaker in the #42 Team Sahlen/HRPWorld.com Corvette and Joe and Wayne Nonnamaker in the similar #43 Team Sahlen/HRPWorld.com machine, and Dominic Cicero and 2006 GT co-champion Marc Bunting in the #57 Stevenson Automotive Corvette; the #41 Team Sahlen/HRPWorld.com Pontiac GTO for Michael Baughman, Sahlen and Joe Nonnamaker; and the Matt Connolly Motorsports BMW M3s for drivers Matt Connolly and Jason Workman in the team's #21 machine and John Lewis and Mexican driver Pepe Montano in the #24 MCM BMW.

Assentato currently leads the Bob Akin Award point standings for the top sportsman driver in the GT class with 709 points. Just four points behind is Joe Nonnamaker, followed by Sahlen with 666 points and Lux with 498 markers.
