SONOMA, Calif. – Scott Dixon surged ahead with three laps left for a victory at Sonoma Raceway on Sunday, while IndyCar points leader Will Power recovered from a mid-race spin to finish 10th heading to the season finale.
Power leads teammate Helio Castroneves by 51 points heading to the double-points finale at Fontana on Saturday. Castroneves struggled to an 18th-place finish at Sonoma.
Simon Pagenaud is 81 points back in third after a third-place finish on a wild day in wine country.
Dixon is out of the race to defend his 2013 title, but he grabbed his 35th win after leader Graham Rahal was forced to pit for gas with four laps left. Dixon slid inside Mike Conway for the lead and held on for Target Chip Ganassi Racing, moving him into a fifth-place tie with Bobby Unser for career victories on the circuit.
Rahal and Conway both tried to push to the finish on low fuel, but neither made it. Ryan Hunter-Reay finished second, and Takuma Sato was fourth.
