WORTHAM, Texas — James Stewart swept the motos Saturday for his second consecutive 450 Class victory to start the AMA Pro Motocross season, and Eli Tomac dominated the 250 Class at Freestone Raceway.

Stewart, the Team Yoshimura Suzuki star from Haines City, Fla., raced to his 18th career victory. Red Bull KTM’s Ryan Dungey, from Belle Plaine, was second in both motos.

“I thought my day went good,” Stewart said. “It was a tough one, but fun. I got two good starts, made quick passes, and set the tone with a good pace. Ryan rode really well, but I did my own thing out front. I knew he’d be there the whole time. I felt like we were even today and if he had gotten out front, he could have done the same thing.”

Stewart extended his championship lead to 14 points over Dungey.

“I got off to good starts in both motos,” Dungey said. “I tried to make a pass happen the whole moto, but there was maybe more I should have done. It just didn’t come together. James is a tough competitor and it’s good for the both of us to push each other to new limits.”

In the 250 Class, GEICO Honda’s Eli Tomac, from Cortez, Colo., also swept the motos for his second career victory. He recently won the AMA Supercross Western Regional title.
