Shane van Gisbergen scored his third win in the last five races Sunday at Sonoma Raceway.

He led 97 of the 110 laps on the 1.99-mile road course north of San Francisco.

Chase Briscoe finished second and was followed by Chase Elliott, Michael McDowell and Christopher Bell.

Advancing to the semifinals of the In-Season Challenge were Tyler Reddick, Ty Gibbs, Ty Dillon and John Hunter Nemechek.

Bubba Wallace continues to hold the final playoff spot. He has a three-point lead on Ryan Preece with six races left in the regular season.

The Toyota/Save Mart 350 at Sonoma Raceway delivered high drama both on and off the track Sunday, as pit crews for Ty Gibbs and Brad Keselowski were involved in a heated altercation during green-flag pit stops on Lap 52.

The incident began when Gibbs, driving the No. 54 Joe Gibbs Racing Toyota, entered his pit stall and clipped the adjacent stall occupied by Keselowski’s No. 6 RFK Racing Ford. In the process, Gibbs’ car reportedly struck a tire being carried by Telvin McClurkin, Keselowski’s front tire changer, twisting his wrist and slowing the stop.

Immediately after the stop, McClurkin approached Gibbs’ pit box to express his frustration. That confrontation quickly escalated into a shoving match between crew members from both teams before NASCAR officials intervened to break it up.

Crew Reactions:

• Jeremy Bullins, Keselowski’s crew chief, stepped in to defuse the situation, telling Gibbs’ jackman, “If we were in that pit box, I would expect him [Keselowski] to do the same [expletive] thing, so we’re good”.
• Ty Gibbs, when asked post-race, defended his actions: “It’s my right of way. They’re on the wall for a reason… that’s kind of the consequence you pay”.

NASCAR’s Verdict:

After reviewing the incident, NASCAR determined that Gibbs had done nothing wrong, citing his position as the lead car entering pit road and the tight spacing between stalls.

While the physical scuffle was brief and no serious injuries were reported, the confrontation underscored the intense pressure and razor-thin margins that define pit road during high-stakes races. With emotions running high and playoff implications looming, this flashpoint may not be the last between these two camps.

As the series heads to Dover Motor Speedway next weekend, all eyes will be on whether cooler heads prevail—or if this rivalry continues to simmer.

AO Racing’s Dane Cameron took the lead with 14 minutes to go when Inter Europol Competition’s Tom Dillmann had a mechanical failure and crashed in turn 3 Sunday (July 13). From there, he rode around under yellow to win the IMSA WeatherTech SportsCar Championship Chevrolet Grand Prix along with PJ Hyett. It is the team’s first LMP2 victory in IMSA.

“Not really the way that we wanted to end the race,” Cameron told NBC Sports’ Matt Yocum in victory lane. “Honestly, I’m so proud of PJ. [His performance] was so phenomenal at the beginning. To lap half the class is incredible. We knew [winning] would be possible, but now we’re rolling.”

United Autosports’ Tom Blomqvist and Dan Goldburg ended up second, followed by TDS Racing’s Hunter McAlrea and Steven Thomas. They finished third on the road, but they were penalized due to an on-track incident and given a post-race drive-through penalty that dropped them to eighth.

TDS Racing’s penalty elevated Riley Motorsports’ Felipe Fraga and Gar Robinson to third overall. The second United Autosports ORECA 07 for Phil Fayer and Ben Hanley were fourth, while PR1 Mathiasen Motorsports’ Benjamin Pedersen and Rodrigo Sales were fifth.

AO Racing’s PJ Hyett started from the overall pole in “Spike.” While United Autosports’ Dan Goldburg had a slightly faster single lap, Hyett was able to pull out to a decent advantage early on.

Meanwhile, TDS Racing’s Steven Thomas, who started third, had an eventual start to his race. First, he spun exiting turn 9 while trying to pass Goldburg for second. Later on, he had contact with Wright Motorsports’ Elliott Skeer, nearly ripping the nose off of Skeer’s Porsche. He eventually had to make an unscheduled stop and dropped to 11th.

Following the first round of stops, there was trouble in Moss Corner. CrowdStrike Racing by APR’s George Kurtz ran in the back of Inception Racing’s Brendan Iribe, spinning both cars out. Pratt Miller Motorsports’ Chris Cumming and Riley Motorsports’ Gar Robinson were collected.

Everyone was able to continue, so the full course caution did not come out. However, both Kurtz and Cumming were forced to make unscheduled pit stops.

Hyett expanded his lead all the way up to 36 seconds when the race’s first full course caution came out 68 minutes into the race. Kurtz appeared to drop a wheel exiting turn 3. With the grass being wet after heavy rains earlier in the day, he lost control and went hard into the tires. Kurtz was able to get out of the car without assistance, but he was out on the spot.

During the caution, the LMP2 teams pitted to put their pros in the car. Cameron was able to turn in some of the fastest laps of the race after the restart in an attempt to get away from Blomqvist.

Behind Cameron, Dillmann was on the move. The defending race winner was able to get past Pedersen in lapped traffic, then made an aggressive move on Blomqvist at Moss Corner to take second. A lap later, Pedersen made a similar move on Blomqvist for third. McAlrea followed past into fourth.

No one could do the distance on fuel from the final restart. Dillmann was the first of the leaders to pit. Pedersen was next, but he was penalized for hitting one of his crewmembers, taking him out of the hunt.

Cameron was the last of the leaders to pit with 42 minutes to go, three laps after Dillmann. The stops were about equal, but Cameron got caught up behind slower traffic in those three laps. As a result, Dillmann beat Cameron out of the pits and took the lead.

Shortly afterwards, Forte Racing’s Mario Farnbacher slid off-course and hit the tires in turn 8 after contact from McAlrea to bring out the yellow. While Farnbacher was able to extricate himself from the tires and drive away, significant time was necessary to reset the tire barrier. McAlrea was given a drive-through penalty due to this contact, but was unable to serve it before the race ended, hence the post-race penalty.

The green came back out with 17 minutes to go. Dillmann had the lead and tried to drive away from Cameron, but trouble struck a couple of laps afterwards. The Inter Europol No. 43 appeared to suffer a mechanical failure that put him off the track and hard into the tires in turn 3.

Dillmann, who was going for back-to-back victories at CTMP, was able to get out of his car on his own, but ended up on the ground afterwards. He was eventually taken away on a stretcher, but gave the assembled fans a thumbs-up before he was loaded into the ambulance.

With the necessary barrier repairs taking up too much time, the remainder of the race ran behind the safety car. As a result, Cameron drove at a reduced pace to victory.

In GTD Pro, Paul Miller Racing’s Neil Verhagen started from pole in his BMW. He spent the first portion of the race slowly but surely driving off from Vasser Sullivan’s Aaron Telitz.

Verhagen led the race without issue until he stopped to hand over to Madison Snow. That resulted in a split pit strategy. AO Racing’s Klaus Bachler chose to stay out as long as possible.

The Kurtz crash occurred right after Bachler stopped for full service. As a result, everyone stopped under the yellow. Laurin Heinrich ended up in the class lead at the beginning of his time in the car.

Heinrich led until he made his final pit stop with 52 minutes to go. That gave the lead over to DragonSpeed’s Albert Costa.

Costa was on a fuel conservation strategy that would have likely forced him to stop with 10-15 minutes to go had the race gone green. However, the Farnbacher crash put the team in position to make their conservation strategy work. When Dillmann crashed, it locked in Costa and Giacomo Altoe into their first victory of the year.

Second went to Corvette Racing by Pratt Miller Motorsports’ Nicky Catsburg and Tommy Milner. Bachler and Heinrich were third, followed by Antonio Garcia and Alexander Sims in the second Corvette. Pfaff Motorsports’ Andrea Caldarelli and Marco Mapelli were fifth in their Lamborghini.

Vasser Sullivan’s Jack Hawksworth started from the GTD pole in his Lexus. On the opening lap, he was able to open a small gap over Winward Racing’s Russell Ward.

The key to Hawksworth being able to hold off Ward was being able to put Altoe in between himself and Ward. With Altoe serving as a blocker, Hawksworth was able to pull out to a seven-second lead.

Further back, Wayne Taylor Racing’s Danny Formal and Triarsi Competizione’s Onofrio Triarsi collided and spun in turn 9. Both drivers were able to drive away. Triarsi was given a drive-through penalty for causing the incident.

The pit stops surrounding the first caution of the race created a split strategy. Wayne Taylor Racing’s Trent Hindman was trying to go the full run from the yellow to the finish, while others stopped shortly after the restart for a splash of fuel.

As a result, Hindman ended with a 23-second lead over Farnbacher with the rest of the class further back. That gave him the ability to conserve some fuel, but he wasn’t going to make it to the finish without help.

Then, Farnbacher crashed and brought out the yellow. While his 20+ second lead was gone, it opened up the possibility of making it to the finish. Dillmann’s crash after the restart allowed Hindman to stretch his fuel to finish, giving himself and Formal their first WeatherTech victory together as teammates.

Unfortunately, the aforementioned incident on the first lap knocked the drink hose loose. Hindman had to drive an un-air conditioned Lamborghini for two hours with no water and was wiped out afterwards.

Ward and Philip Ellis finished second and expanded their points lead. Hawksworth and Parker Thompson were third, then DXDT Racing’s Alec Udell and Robert Wickens. The Heart of Racing’s Roman De Angelis and Casper Stevenson were fifth.

WeatherTech teams will take the next three weeks off. Next up on the schedule is the IMSA SportsCar Weekend at Road America for all four classes. The race will air exclusively on Peacock Aug. 3 at 2 p.m. ET.
