Sonoma Raceway is one of only two road courses on the Sprint Cup schedule, meaning it's about as good of a chance as any for a dark-horse driver to shake up the running order at the end of the race. Turning left and right can lead to a ton of surprises, including when Kansas native Clint Bowyer won the first road course race of his career last year.
Crown Martin Truex Jr. the latest surprise road course winner.
The second Michael Waltrip Racing driver in a row to win in wine country, Truex ended a losing streak of over half a decade on Sunday by crossing the line first. He dominated the end of the event, pulling away from the rest of the pack to score an authoritative victory and set himself up to make moves down the stretch.
But not every driver was as fortunate as Truex on Sunday. Here are the folks who had standout weekends, for better or worse.
