Ricky Taylor moved his No. 10 Wayne Taylor Racing Cadillac DPi-V.R to the top of the third Continental Tire Monterey Grand Prix practice session Saturday morning with a fast lap of 1m18.216s. Following Nissan’s pace to close Friday, the slim margin among the leading Prototype entries should ensure a tight qualifying session as PR1/Mathiasen Motorsports’ Jose Gutierrez pushed the No. 52 Ligier JSP217 (+0.069s) and an ill Ryan Dalziel shadowed Taylor in third with the No. 2 Nissan Onroak DPi (+0.078s).

The ridiculously narrow leads were also found in the WeatherTech SportsCar Championship’s GT Le Mans and GT Daytona categories.

In GTLM, Ford returned to P1 as Chip Ganassi Racing’s Dirk Muller (1m22.678s) took control in the No. 66 Ford GT. Risi Competizione’s Toni Vilander came close in the No. 62 Ferrari 488 (+ 0.093) and BMW Team RLL’s Alexander Sims claimed third in his No. 25 BMW M6 (+0.432). Vilander’s Ferrari completed roughly half of the one-hour session before it was taken back to the Risi trailer. Vilander led GTLM at the time of their stoppage.

GTD saw the No. 48 Paul Miller Racing Lamborghini Huracan GT3 driven by Bryan Sellers (1m24.711s) edge Jeff Segal in the No. 86 Michael Shank Racing Acura NSX GT3 (+ 0.045s) and Turner Motorsport’s Klingmann in the No. 96 BMW M6 GT3 (+0.276s).

Daniel Morad was barely able to hold the GTD lead in his No. 28 Alegra Motorsports Porsche 911 GT3 R (1m25.816s) thanks to Colin Braun, who was fractionally slower (-0.015s) in the No. 54 CORE autosport Porsche 911 GT3 R. Jens Klingmann was third in the No. 96 Turner Motorsport BMW M6 GT3 (-0.219s) as the session started and finished without interruption.
