The Monster Energy/Graves Motorsports Yamaha team continued its domination of the 2015 MotoAmerica AMA/FIM North American Superbike Championship at Barber Motorsports Park on Sunday, but this time it was Josh Hayes' turn to steal back some valuable points from his teammate Cameron Beaubier. With Beaubier crashing out of the lead in race one, Hayes took full advantage to earn maximum points and basically erase the 26-point lead that Beaubier had left Road America with. In race two, Beaubier bounced back to win with Hayes second, but his 26-point lead is now just six points.

Josh Chisum Racing’s Tyler O’Hara finished third in the Superstock 1000 Race 1 and Tuned Racing’s Jason Aguilar finished third in Superstock 600 Race 1.
