captured the overall and Prototype class pole for Sunday’s Continental Tire Monterey Grand Prix in his No. 2 Extreme Speed Motorsports HPD ARX-03b, in a thrilling battle with Richard Westbrook for the top spot.

Meanwhile Antonio Garcia took Corvette Racing to its second straight pole – after co-driver Jan Magnussen did so in Long Beach – in GT Le Mans.

Prototype:

“JVO,” who led second practice, and Westbrook in the No. 90 Spirit of Daytona Corvette DP traded fastest laps at a breakneck pace during the 15-minute session. But van Overbeek’s 1:18.561, set on his ninth timed lap, beat Westbrook’s 1:18.788.

Van Overbeek will share with Ed Brown, Westbrook with Michael Valiante on Sunday.

The second ESM HPD, of Ryan Dalziel and Scott Sharp, starts third with OAK Racing’s No. 42 Morgan Nissan of Gustavo Yacaman and Alex Brundle making it three P2-spec cars in the top four overall.

GT Le Mans:

Garcia, who will co-drive the No. 3 Corvette Racing Corvette C7.R with Jan Magnussen, led a tightly bunched top five in GTLM. Only 0.437 of a second covered two Corvettes, two BMWs and one Porsche.

Garcia’s early lap of 1:22.373 beat out the No. 56 BMW Team RLL BMW Z4 GTE of John Edwards, at 1:22.578. Edwards will share the car with Dirk Mueller.

It was still a good day for Edwards, who shared the car as it paced both practice sessions and was part of the winning lineup in the Continental Tire SportsCar Challenge race earlier Saturday.

Nick Tandy was third in the No. 911 Porsche North America Porsche 911 RSR at 1:22.678. Tandy seeks a repeat victory after taking the American Le Mans Series GTC class win last year with MOMO NGT Motorsport; he’ll co-drive the No. 911 with Richard Lietz.

Oliver Gavin was fourth in the No. 4 Corvette C7.R he’ll share with Tommy Milner; GTLM points leaders Andy Priaulx and Bill Auberlen start fifth in the No. 55 BMW Team RLL BMW Z4 GTE.

The best SRT Viper was sixth (No. 91 of Dominik Farnbacher and Marc Goossens) with the best Ferrari seventh (No. 62 Risi Competizione entry of Giancarlo Fisichella and Pierre Kaffer).

Prototype Challenge: 

Times in the PC qualifying sessions got into the 1:20s, in a four-horse race between the Starworks, RSR, 8Star and CORE teams.

Ultimately it was Junqueira, who also won the Sebring pole last race, who just broke into the 1:19 range and ended at a 1:19.929 on his ninth lap. He bettered it on his tenth lap, at 1:19.723.

It’s his second straight pole position in the No. 09 RSR Racing Oreca FLM09, and he’ll share the car with Duncan Ende.

Junqueira had a spin during the session but was able to recover rather nicely, all things considered.

Renger van der Zande ended second in the No. 8 Starworks entry, adorned in a new Martini livery this weekend that he’ll share with Mirco Schultis, after a best time of 1:20.117.

Sean Rayhall took the No. 25 Takis 8Star Motorsports entry to third at 1:20.421; he’ll share with the returning Luis Diaz on Sunday.

CORE autosport seeks its third straight win to open the season from fourth, with Jon Bennett and Colin Braun in the team’s No. 54 entry, and Alex Tagliani was fifth in RSR’s second car – the No. 08 he’ll share with Chris Cumming.

GT Daytona:

GTD qualifying was interrupted when Jack Gerber’s No. 51 Spirit of Race Ferrari 458 Italia GT3 went off course at Turn 4 and caused a red flag lasting more than five minutes.

But the session was able to restart and fliers could resume at that point. Keen appeared safe at a 1:26.962 before Pumpelly threw down on his eighth and final timed lap of the session to lay down the pole time of 1:26.695.

Pumpelly will co-drive the No. 45 Flying Lizard Motorsports Audi R8 LMS with Nelson Canache.

Keen starts second in the No. 22 Alex Job Racing Porsche 911 GT America that he’ll co-drive with Cooper MacNeil, who is still en route to Monterey after a final he took at the University of Colorado-Boulder this week.

Christopher Haase, the Rolex 24 at Daytona polesitter, brought the No. 48 Paul Miller Racing Audi R8 LMS to third at 1:27.101. He shares with Bryce Miller in the No. 48 car.

Kyle Marcelli was best of the Ferraris in the No. 64 Scuderia Corsa Ferrari 458 Italia GT3 at 1:27.121, with Dion von Moltke posting an identical time in the No. 35 Flying Lizard Motorsports Audi R8 LMS. Marcelli will co-drive with Stefan Johansson, von Moltke with Seth Neiman on Sunday.

Sebring winners Magnus Racing will roll off ninth, with Andy Lally clocking in at 1:27.448 in the No. 44 Porsche 911 GT America.

Sunday’s doubleheader will start at 1 p.m. ET with the PC/GTD race and will be followed by the P/GTLM race at 5:30 p.m. ET.
