Double vision: Drivers who swept Sonoma, Watkins Glen

Since 1989, the Monster Energy NASCAR Cup Series schedule has had just two road courses throughout the season (a third -- Charlotte Motor Speedway in the fall -- was added last year). Only four drivers in five instances have pulled off the road-course double, sweeping both Watkins Glen International and Sonoma Raceway. Martin Truex Jr. takes aim at the road-course double this year after winning at Sonoma in June ... and finishing runner-up last year at Watkins Glen.
