Monster Energy Kawasaki’s Eli Tomac passed defending champion Ryan Dungey in the closing laps of Saturday night’s 450SX Main Event to claim the win in Oakland, Calif. It was the second consecutive victory for Tomac, who now trails Dungey by just 17 points.

Tomac and Dungey struggled with the early start in Oakland, failing to transfer out of Heat 2. But the extra track time would pay dividends as both would go on to win their respective semi races and eventually battle for the victory in the main.

“I had to work for that win tonight and it feels good to grab my second straight win,” said Tomac. “The track was real technical and I had a good flow going in the middle of the race. I snuck to the inside of [Dungey] and kept pushing until the checkered flag.”

While it was Vince Friese who grabbed the holeshot in the main, Dungey quickly charged past him to take over the top spot. Tomac, however, had had a less-than-stellar start and was buried in eighth place at the end of the first lap. But Tomac quickly went to work and found himself in podium contention just before the halfway mark.

After disposing of Cooper Webb for second, Tomac set his sights on Dungey and would pull to his rear fender with five minutes left on the clock. A torrid pace through the whoops gave Tomac the inside line and ultimately the race lead. Tomac went on to win by 10 seconds over the KTM rider.

Webb held on to finish third, capping off a night of firsts for the standout rookie. Webb kicked off the day by earning his first pole, then his first heat race victory and finally his first 450SX podium.

Just off the podium was Jason Anderson, who edged out rival Cole Seely. Davi Millsaps, Blake Baggett, Chad Reed, Marvin Musquin and Dean Wilson rounded out the top 10 in the Bay Area.

In the 250SX Class, it was yet another dominant performance out of Pro Circuit Kawasaki rider Justin Hill. The #46 led every lap en route to his third consecutive victory and the championship lead.

“The track was insane, extremely rough, rutted and technical,” said Hill. “I was able to get out front early, but had a little scare halfway through with a small crash. Fortunately, I pulled it together and managed to hold on for the win. I’m stoked to gain control of the points lead and walk away with the red plate.”

Martin Davalos took the holeshot in the 250SX Main while Austin Forkner went down from second place in Turn 2, triggering a massive pileup. Hill was able to make it through and soon passed of Davalos for the lead. Meanwhile, Jimmy Decotis and Shane McElrath were battling for third. While McElrath emerged triumphant in that battle, it was not enough to hold on for the points lead.

Hill almost threw it all away though when he went down from the lead after hitting a piece of wood in a deep rut in the middle of the race. Fortunately for Hill, he had an eight-second lead at the time and was able to remount in the lead.

Davalos went on to finish second ahead of Mcelrath, Decotis and Phil Nicoletti.
