The 2015 Lucas Oil Pro Motocross Championship, sanctioned by AMA Pro Racing, hosted its fourth round on Saturday with its lone visit to the southeast region of the U.S. for the Red Bull Tennessee National at Muddy Creek Raceway. One week after he emerged with his first overall win of 2015 as well as the 450 Class points lead, Red Bull KTM's Ryan Dungey became the first two-time winner at Muddy Creek while also keeping KTM's undefeated 450 Class record at the facility intact. In the 250 Class, Yamalube/Star Racing Yamaha's Jeremy Martin put forth another strong effort to claim his third overall win in four rounds this season, becoming the third different 250 Class winner in three races at Muddy Creek.
