The Pro Mazda Championship Presented by Cooper Tires will kick off its 2014 season with a pair of races this weekend on the streets of St. Petersburg, Fla. A stellar 20-car lineup will contest the Allied Building Products Grand Prix of St. Petersburg, headed by Orlando’s Spencer Pigot, a rising star of American motorsports who took the recent four-race Cooper Tires Winterfest mini-series by storm with two victories and four pole positions.
