Monster Energy Graves Yamaha teammates Cameron Beaubier and Josh Hayes both came away with MotoAmerica Superbike victories on Sunday at Mazda Raceway Laguna Seca.

Hayes finished third and first in the two races on WorldSBK weekend, but lost another four points to Beaubier in the race for the 2016 championship with one round remaining.

Beaubier takes a 29-point lead over Hayes to New Jersey with Yoshimura Suzuki’s Toni Elias another six points behind in third place.

Elias’ Yoshimura Suzuki teammate Roger Hayden basically took himself out of championship contention with a crash in race one and a fourth-place finish in race two.

Meen Motorsports’ Josh Herrin meanwhile became the second MotoAmerica champion of the 2016 season as he was crowned the Superstock title winner after finishing eighth in race two.

Australian Superbike regular Brayden Elliott was once again on track with the ADR Motorsports squad, finishing 15th in race one and improving to 13th in the second. David Anthony (Latus Motors Kawasaki) went DNF-14.
