Aitken and Tan Battle for Winterfest Pro Mazda

An international field prepares for an intense season with the pre-season Cooper Tires Winterfest.

Two youngsters who have honed their skills in Europe in recent years staged a fine battle for the first three Pro Mazda Championship Presented by Cooper Tires races of the 2015 Cooper Tires Winterfest, with Briton Jack Aitken (Team Pelfrey) narrowly holding off Andretti Autosport's Weiron Tan in two of three races at NOLA Motorsports Park.Aitken, 19, from London, England, returned to the Pro Mazda ranks following an impressive debut performance in last year's season finale at Sonoma Raceway, where he finished fourth. His focus this year will be on a return to the Formula Renault Eurocup, but he used the opportunity to gain some racing mileage during the Winterfest to excellent effect.
