LEXINGTON, Ohio — Scott Pruett held off Ricardo Zonta down the stretch to win the Grand-Am Rolex Series race at Mid-Ohio Sports Car Course on Saturday.

Pruett, co-driving the No. 01 TELMEX Lexus Riley with Memo Rojas, beat Zonta's Ford Lola by .491 seconds in the EMCO Gears Classic.

The defending series champions overcame a first-lap penalty that put them a lap down and went into the points lead in the Daytona Prototype class.

The production-based GT class was won by Dirk Werner and Leh Keen in a Porsche GT3. They started last in the field of 32 cars, after failing post-qualifying inspection on Friday. Keen qualified the car on the GT pole before the penalty.
