NASCAR results: William Byron dominates at Watkins Glen; highlights, full finishing order, updated playoff bubble

William Byron on Sunday proved once again that when a Hendrick Motorsports entry dials everything in, they are nearly unbeatable.

Byron led 63 of 90 laps en route to a dominant win at the Go Bowling at the Glen. Byron benefitted from a pit-lane violation committed by then-leader Michael McDowell on the first round of green-flag pit stops, assumed the lead on McDowell's pass through and never looked back. Pole-sitter Denny Hamlin never could muster enough to mount a serious challenge to the No. 24 machine, which had opened up a three-second lead by the final lap.

"I did a lot of driving in iRacing this week, got a new simulator at home, so thanks to those guys," Byron said after his first career road course win.

After the elation of last week's win, McDowell had a nightmare of a day, as the team was penalized on pit road again later in the race for having a man over the wall too early. They later retired the car with engine failure.

While it was all smiles for the No. 24 team, Hendrick teammates Kyle Larson and Chase Elliott were snake-bitten in upstate New York. Larson was in the mix for the win going into the second and final round of green-flag pit stops, but a speeding penalty shuffled him back toward the middle of the field. Larson wound up 26th after an incident with Austin Dillon going into the final corner of the race.

Elliott — in must-win mode to make the playoffs — brought out the only caution of the day on lap 55 when he ran out of fuel on the backstretch. Elliott started 15th and the team opted for an alternative pit strategy hoping things would break their way, but a miscalculation on when to refuel doomed the No. 9.

Go Bowling at the Glen top drivers and best bets

Chase Elliott's only chance at a playoff spot is a win in one of the next two races, and given that he's the winningest active driver on road courses with seven, he's the favorite this weekend at Watkins Glen, according to BetMGM. Kyle Larson has won the past two races at Watkins Glen and enters the weekend at 5½-to-1 odds. Current points leader Martin Truex Jr. has six career road-course wins to his name and is 7-to-1 entering the weekend. Tyler Reddick, who won earlier in the season at Circuit of the Americas, enters the weekend with 9-to-1 odds.

Best odds to win

• Chase Elliott +300• Kyle Larson +550• Martin Truex Jr. +700• Tyler Reddick +900

Yahoo Sports' Nick Bromberg wrote earlier in the week on the betting forecast and suggests good mid-tier odds on Chris Buescher (+2200), who has won the past two races on the trot, and Austin Cindric (+2400), who has bagged a pair of top-10s on road courses this season at COTA and the Chicago street race. If you want to take flyer on a long shot, Bromberg notes that Erik Jones (+25000) has four top-10s at Watkins Glen in five career starts there.

Go Bowling at the Glen weather

The forecast is partly cloudy for Saturday's Cup Series practice and qualifying runs, but a 52% chance of rain looms for race day. NASCAR's short-track and road-course packages include windshield wipers and grooved tires that can run on damp asphalt but not with rain coming down or standing water on the track.
