SOUTHWICK, Mass. — Ryan Dungey raced to his seventh straight AMA Pro Motocross victory Saturday, winning the first 450 Class moto and surviving a pit stop to finish second in the second.

The Red Bull KTM rider from Belle Plaine had an 85-point lead over Mike Alessi, the Suzuki rider from Victorville, Calif., who was second and sixth in the motos to finish second overall.

In the 250 Class, Kawasaki’s Blake Baggett of Grand Terrace, Calif., raced to his fourth victory of the summer, extending his lead in the championship. He was third in the first moto and won the second.

Honda’s Ashley Fiolek of St. Augustine, Fla., raced to her third straight victory in the Women’s Motocross Championship, sweeping the motos.

In the first 450 Class moto, Alessi grabbed the holeshot, while Dungey quickly worked his way forward from a third-place start. The points leader paced his main championship rival for five laps before making a pass for the lead and pulling away for the win.

In Moto 2, Dungey once again found himself slotted behind Alessi, who captured the holeshot. This time, Dungey wasted no time taking over the top spot, crossing the line at the front of the field at the conclusion of the opening lap. After opening up a lead, Dungey tipped over on the sixth lap, losing the lead to Alessi.
