Tony Stewart ended a three-year NASCAR Sprint Cup victory drought by winning under huge pressure from Denny Hamlin at Sonoma.
Having qualifying 10th before dropping down the order in the middle of the race, Stewart chose to make an early final pitstop to pre-empt a potential debris caution.
The yellow came and Stewart stayed out as all the frontrunners pitted, enabling him to take the lead with 20 laps to go.
With the bunched-up pack behind him, the Stewart-Haas Chevrolet driver made it through another caution and restart in the lead when Michael McDowell parked his car on the side of the track.
After holding out until the final lap, it looked like the win was lost when Hamlin took Stewart on the inside to steal first place, before Stewart snatched it back with only two corners to go.
The win was Stewart’s first since June 2013 and gave him hope of reaching the Chase in his final season before retiring.
Having missed eight races at the start of the year due to back injuries from a pre-season dune buggy crash, Stewart must get into the top 30 in the championship to be Chase eligible regardless of his win status but the Sonoma victory brings him up to 32nd.
The closing lap fight livened up an otherwise uneventful race.
Martin Truex Jr joined Hamlin in pressuring Stewart before contact between them with eight laps to go.
Joey Logano finished third, with polesitter Carl Edwards, hampered by a long third stop, fourth ahead of Truex.
Road course expert AJ Allmendinger was a contender for the win before receiving a penalty for an uncontrolled tyre at his final pitstop.
It set him back to 35th but he made it up to 14th by the time the flag fell.
Kurt Busch had a disappointing race, struggling with a car that swung towards oversteer and losing six places from his qualifying position to finish 10th.
Aside from the McDowell caution and two for debris, the only other yellow came when Clint Bowyer’s HScott Chevrolet caught fire due to an electrical problem just six laps into the race.
