The stifling heat of Jacksonville, FL, was a new challenge for the riders to overcome in their goal of becoming the 2019 Pro Motocross Champion. Despite having little experience in the humidity this season, the Monster Energy/Star Racing/Yamaha riders dominated by taking two of the three podium spots. It was Justin Cooper who went two-two for his first ever overall pro win. Dylan Ferrandis worked his way from fifteenth to fourth in the first moto. He won the second moto and was up on the podium with a second-place overall. Nichols ended the day in seventh, Masterpool was fifteenth, and Oldenburg sixteenth.
