SVG's Playoff Life, Larson's Home Track, and the In-Season Challenge: What to Watch Sunday at Sonoma
Welcome to the Happy Hour Racing Race Preview - the storylines and what-to-watch companion to Friday's Track Preview. Every Saturday, we break down the human and competitive story heading into Sunday's race.
The Short Version
The NASCAR Cup Series runs the Toyota/Save Mart 350 at Sonoma Raceway this Sunday, June 28. Green flag is 3:30 p.m. ET on TNT and HBO Max. This is Race 18 of 36 in the 2026 season and the last road course on the schedule before the playoffs. It is also Round 1 of the 2026 In-Season Challenge, a 32-driver bracket tournament with a $1 million prize available for a perfect prediction. If you want one reason to tune in: Shane van Gisbergen is 5 points below the playoff cutline and this is his best track in NASCAR. What he does Sunday may define his entire season.
The Biggest Storyline: SVG Needs This One
A year ago at Sonoma, Shane van Gisbergen started from the pole, led 97 of 110 laps, and won by a comfortable margin. He made it look routine. This year is a different situation.
After getting collected in an incident at the Naval Base Coronado street course last weekend, van Gisbergen scored just 1 point and his finishing position dropped to 38th. He fell from 12th to 17th in the Chase standings. He is now 5 points below the final playoff position, held by Ryan Preece.
Sonoma is the last road course of the regular season. The next four races are ovals: Chicagoland, Atlanta, North Wilkesboro, and Indianapolis. Van Gisbergen has improved on ovals in his second Cup season, but not to the point where he can count on making up ground there. If he leaves Sonoma still below the cutline, his championship run is in serious trouble.
He starts sixth on Sunday after being fastest in Group 1 of qualifying. The speed is there. The pressure is something else entirely.
The Other Storyline: Larson at His Home Track with 41 Races Without a Win
Kyle Larson grew up in Elk Grove, California, about 90 miles from Sonoma Raceway. He has won here twice, most recently in 2024. He is the defending Cup Series champion. And he has not won a race in 41 starts.
That streak dates back to the Kansas race in spring 2025, over a year ago. Larson has been quick, leading 573 laps on the season and collecting seven top-five finishes. He finished third at Coronado last week. But the wins have not come.
Larson himself is not panicking. "I don't feel bummed or sad or anything of that nature," he said. "We have been consistent." He starts third on Sunday at a track where he has proven he can win. If there is a place to end the drought, this is it.
Drivers to Watch and Why
Shane van Gisbergen is the driver everyone else is racing against on road courses. He has won seven NASCAR Cup road course races. At Sonoma last year he was in a different class. On Sunday he needs to prove that was not a fluke and that his season still has a future. Start position: sixth.
Kyle Larson has the speed and the track history here. He grew up watching NASCAR from the hills around this region, and he has celebrated in victory lane at Sonoma before. Third on the grid means he is right where he needs to be to make a run early and control the race. A win here would be one of the more satisfying storylines of the season.
Tyler Reddick leads the Cup Series standings and has been the best driver in the field for most of 2026. Road courses have been his friend - he has four career wins on them. He starts 11th but has shown the ability to carve through the field. He also needs to advance in his In-Season Challenge matchup against Alex Bowman.
Denny Hamlin has won three times in recent weeks and is the hot hand in the sport right now. His 23XI Racing Toyota operation has hit a groove. He starts ninth and is paired against Ty Dillon in the In-Season Challenge bracket. He has not been a road course specialist, but he has enough experience to stay out of trouble and capitalize on other people's mistakes.
Connor Zilisch is the name to watch if you enjoy watching rookies turn a race upside down. The 19-year-old was leading at Coronado last week before getting collected in an incident. Oddsmakers have him as a top-five favorite. He was not seeded high enough to make the In-Season Challenge bracket, so Sunday is purely about the race result for him - and he has nothing to lose.
What to Watch for Sunday
The first lap through the hairpin. Ty Gibbs won the pole with a lap of 1:14.829 and will lead the field into Turn 1. Road course starts at Sonoma are always chaotic, and the carousel section historically sees contact in the opening laps. Gibbs gets his best-ever starting spot; the question is whether he can hold it under pressure.
Bubba Wallace from the back. Wallace crashed in qualifying and will start at the rear of the field in a backup car. Watch how far he climbs - and watch how many incidents he creates or avoids while fighting through traffic.
The In-Season Challenge within the race. There are 16 head-to-head matchups playing out inside the overall race. If you want extra stakes in every battle on track, pull up the bracket before the green flag. Every position swap between paired drivers is a bracket outcome changing in real time. Key matchups to watch: Reddick vs. Bowman (the #1 seed trying to advance), Larson vs. Herbst, and Elliott vs. Gragson.
Wind. The forecast calls for 10 to 20 mph west winds during the afternoon. Sonoma has 160 feet of elevation change and several exposed sections where wind direction matters for braking. Look for drivers to adjust their lines in the later stages, especially if conditions pick up.
Christopher Bell's wrist. Bell qualified 14th with a fractured left wrist. He has said road course steering is the hardest part of the injury to manage. Watch whether he fades in the second half as fatigue sets in, or whether he finds a way to push through. Bell has three career road course wins - he knows how to drive these tracks.
The Fan Debate
After Round 1 of the In-Season Challenge, fans will start arguing about whether this format actually works on a road course. The road course specialists - SVG, Larson, AJ Allmendinger - have a massive natural edge here that oval guys do not have. Is that fair for a bracket that is supposed to test the best overall driver? Or is that exactly the point: win on your best track, then survive the ovals. Bring it up in the group chat before Sunday and see what happens.
The Bottom Line
Van Gisbergen dominated Sonoma last year like few drivers dominate anything. If he races Sunday like he did in 2025, nobody in the field can match him. If his San Diego problems carry over, Sonoma may turn out to be the race that ended his 2026 playoff run. That story alone is worth watching. Add Larson chasing a drought-ending win at his home track, plus 16 bracket matchups playing out in real time, and Sunday's race has more layers than most. Set a reminder for 3:30 ET.
