LAS VEGAS — An incredible race-long scramble among the day’s front-running trio of veteran Aric Almirola and young talents Connor Zilisch and Jesse Love ended in favor of the experienced Almirola, but he really had to earn this trophy in Saturday’s Focused Health 302 NASCAR Xfinity Series playoff race at Las Vegas Motor Speedway.

Almirola, who led a race-best 107 of the 201 laps, took the lead for good from the season’s most dominant driver, Zilisch, with nine laps remaining and held off the championship leader by .696 seconds in one of the most competitive races of the season.

The win for the 41-year-old Almirola — who is racing part-time this season — gives his No. 19 Joe Gibbs Racing Toyota the first automatic berth for the owner’s championship in the Nov. 1 season-ending Championship 4 finale at Phoenix Raceway.

It was the third win of the 2025 season and 10th of his career for Almirola, who made the dramatic race-winning move — diving low on the 19-year-old Zilisch — and then had to out-run and out-maneuver the talented young star in the closing laps.

Almirola’s victory settles an owner’s championship position but also means the final four championship race is still open to four drivers — at least two of which will now advance based on points.

“Such an awesome opportunity to go race for an owner’s championship with [Gibbs’ late son] J.D. Gibbs’ name on the car,” Almirola said. “I’m having so much fun. This is the time of my life.

“Our car was good. Our car was really good, but the longer I ran the tighter I got and I was just struggling on the long run at the beginning of Stage 3 and finally on that re-start [with 23 laps remaining] I took off incredibly tight and couldn’t get going and was able to go chase the 88 [Zilisch] down. He looked pretty loose and I was able to capitalize on that.

“It was awesome racing them.”

Zilisch’s runner-up finish extends his series record consecutive top-five efforts to 18 races. He’s finished first or second place an incredible 11 of the last 13 races. However, that streak of success was no comfort in the immediate moments after Saturday’s checkered flag. He even apologized to his JR Motorsports team on the cool-down lap for not being more aggressive in the race’s closing laps.

“The frustration just comes from the fact this means so much to me and the chance to lock into Phoenix,” said Zilisch, who boosted his advantage in the championship to 82 points above the four-driver playoff cutoff line.

“I gave it my all and I drove as hard as I could. But I guess that’s all we had today. I just have to do a better job.”

“We put ourselves in the right spots, but unfortunately, I just didn’t come away with it,” he added. “Plus, 82 [points] is not bad; it could have been a lot worse, but having another “win” sticker on this thing would have been a lot better.

Zilisch’s JR Motorsports teammate Justin Allgaier, Saturday’s polesitter and the defending race winner, finished third followed by Hendrick Motorsports’ development driver Corey Day and Big Machine Racing’s Nick Sanchez.

Love, who led three times for 22 laps, finished sixth in the No. 2 Richard Childress Racing Chevrolet. He got caught up racing hard with Sanchez in the closing laps after running among the top three for most of the day. He was frustrated and he and Sanchez had words on pit road following the checkered flag.

“I had words with him and obviously I’m extremely pissed off,” said Love, who is now 20 points above the cutoff line. “It was my fault I was in the spot racing him. … I don’t run into people and don’t put people in bad spots for no reason and that’s why I’m upset about it.

“I did a lot of things really good tonight and I did a lot of things really really bad tonight,” Love added.

For his part, Sanchez said he was just racing hard, and although he is no longer playoff-eligible, he still intends to race hard for wins in these final races of the season.

Ryan Sieg, Taylor Gray, playoff driver Sam Mayer and Austin Hill rounded out the top 10.

Beyond Zilisch’s huge lead in the playoff standings, Allgaier is second, 44 points up on the cutoff. Love’s sixth-place showing moved him from fifth place into third place and Mayer is fourth, eight points above the cutline.

JGR’s Brandon Jones, who finished 13th Saturday, is now fifth in points, minus-8. Mayer’s Haas Factory Team teammate Sheldon Creed, who finished 11th, is now 21 points off the cutline. Zilisch’s JR Motorsports teammates, Carson Kvapil, who finished 15th and Sammy Smith, who finished 20th, are now 22 and 24 points, respectively, below the four-driver cutoff.

The series returns to playoff action next week at the 2.66-mile Talladega Superspeedway for next Saturday’s United Rentals 250 (4 p.m. ET, The CW, MRN Radio, SiriusXM NASCAR Radio). Sammy Smith is the defending race winner.

NOTE: Post-race inspection in the Xfinity Series garage concluded without issue, confirming Almirola as the race winner. No cars will return to the NASCAR R&D Center in Concord, North Carolina.

LAS VEGAS — All of the NASCAR Cup Series alpha dogs have advanced to the Round of 8. Let them bark.

Hendrick Motorsports, Joe Gibbs Racing and Team Penske — the flagship team for all three manufacturers — fill the eight positions in the Round of 8. This year joins 2021 as the only time that the eight spots were represented entirely by the three heavyweight organizations. Seven of the eight drivers in this year’s Round of 8 have appeared in multiple Championship 4 battles. Excellence personified.

“I wouldn’t say there’s any surprises in the Round of 8,” reigning Cup champion Joey Logano said on Saturday at Las Vegas Motor Speedway. “I think they are all capable of winning the championship this year — every one of them. There are none that are like, ‘I can’t believe this guy made it this far.’ I think you’ve got the best eight teams going for it; it’s going to be a battle right until the end.

“I don’t see a clear favorite or a clear this person is going to kill them all. It seems like it’s going to be close all the way to the end.”

The metrics skew in favor of these eight drivers. Every driver but Logano has multiple victories in the opening 32 events of the season and has accounted for 21 of the 26 wins on ovals. Josh Berry, Austin Cindric, Ross Chastain, Bubba Wallace and Austin Dillon are the outliers.

Over the six previous 2025 playoff races, Chase Briscoe, a JGR newcomer, has tabulated the most points with 233. Christopher Bell, his Joe Gibbs Racing teammate, ranks second with 223 points scored. All eight drivers are within 48 points of each other.

“These are some of the best teams,” 2025 Regular Season Champion William Byron said. “It’s pretty straightforward to get here this year. I think that changed with Talladega not being in the Round of 12. It made that round — I would say — based on merit. These are some great race teams.”

The consensus among the Round of 8 drivers is that experience pays dividends. Four of the eight drivers are Cup champions, no doubt future Hall of Famers. Denny Hamlin’s 59 career victories easily secure him a spot among NASCAR immortals. The stock for Bell, Briscoe and Byron continues to rise with each passing season.

“There is a lot of experienced drivers that made it to the Round of 8, and I think that experience allows you to get to the Round of 8 throughout the playoffs,” 2021 champion Kyle Larson said. “I guess I never thought about that, but it’s impressive, and hopefully we can do a good job to make it on.”

The lone driver to not have a prior Championship 4 berth is Briscoe, whose deepest run was to the Round of 8 in 2022 with Stewart-Haas Racing. The script has flipped on his outlook as he had an outside chance of advancing to the Championship 4 that season.

“You don’t luck your way into the Round of 8,” Briscoe said. “I feel like it’s probably the strongest Round of 8 we’ve ever had. Just when you look at the teams and drivers. It’s not going to be easy. The points are tighter than they’ve ever been; nobody has separated themselves. It’s going to be tough, but at this time of the year, you have to go perform.

“I at least know the intensity of the Round of 8. It was a way different situation because we were complete underdogs. It felt different from what it feels like right now, but at least having that experience and knowing how that Round of 8 feels is good. There is a reason the same guys get there year after year, and they have a lot of experience doing it.”

The points reset would concur with Briscoe. After the reset from the Round of 12, Hamlin is scored as the No. 1 seed, only eight points above the cutline. That’s the fewest in playoff history by a considerable margin, with the smallest gap previously being 18 points in 2019.

All eight drivers know getting through Las Vegas unscathed is paramount. The middle race in the round is at the hallowed grounds of Talladega Superspeedway, where a driver’s destiny can oftentimes be in the hands of their competition. Hamlin knows that firsthand, which is why winning the Busch Light Pole Award for Sunday’s South Point 400 (5:30 p.m. ET, USA Network, HBO Max, PRN Radio, SiriusXM NASCAR Radio, NBC Sports App) holds a high magnitude.

“We’ve got really two races to make it,” Hamlin said. “Talladega is going to be a coin flip for all of us, so we have two races to try to execute the best we can and hopefully speed wins out. Hopefully, you don’t get unlucky. That’s going to be the difference. Someone is going to get lucky and someone is going to get unlucky to either make or not make the final four.”

Playoff drivers governed the field in qualifying on Saturday, filling up the top six positions. Ryan Blaney, 2023 Cup champion, is the only driver not to crack the top 10 and will take the green flag from 14th position. The Round of 8 contestants have combined to win five of the last six races at Las Vegas.

LAS VEGAS — Denny Hamlin led a Joe Gibbs Racing sweep of the top three qualifying positions for Sunday’s South Point 400 playoff race at Las Vegas Motor Speedway (5:30 p.m. ET, USA Network, HBO Max, PRN Radio, SiriusXM NASCAR Radio, NBC Sports App).

Hamlin’s No. 11 JGR Toyota claimed the Busch Light Pole Award on Saturday afternoon with a lap of 184.849 mph around the 1.5-mile Vegas high banks — just bettering teammates Chase Briscoe in the No. 19 Toyota and Christopher Bell in the No. 20 Toyota Camry. All three are current NASCAR Cup Series Playoffs drivers. It was Hamlin’s first pole at Las Vegas.

And it’s the second time this season Toyota has swept the top three qualifying spots — the last time was at Indianapolis Motor Speedway during the summer, when the make swept the top five. It was the 25th time in Toyota’s history that it swept the top three starting positions on the grid.

“I felt good about it, truthfully,” said Hamlin, the 2021 Las Vegas playoff race winner and the current championship leader. “There wasn’t a whole lot left out there for it. But a great job by this team to get my car good. It was good in the short run in practice as well, got to work on it for the long run for tomorrow.

“But Saturday [qualifying] has always been our Achilles’ heel at this race track, and that’s a great way to turn that around.”

Heavy winds affected both practice and qualifying sessions, with drivers reporting substantial headwinds on the backstretch.

The eight playoff drivers starting this three-race penultimate round of competition all had solid qualifying performances. However, beyond the Gibbs front trio, Hendrick Motorsports’ Chase Elliott was fourth quickest, followed by his Hendrick Chevrolet teammates William Byron and Kyle Larson — a three-time winner in Sin City.

Reigning series champion and defending Las Vegas playoff race winner, Joey Logano, was ninth fastest in the No. 22 Team Penske Ford. His teammate, 2023 series champ Ryan Blaney, will roll off from the 14th on the grid.

Ross Chastain was fastest in Group A from practice, but his No. 1 Trackhouse Racing Chevrolet brushed the wall and the team spent the closing minutes of the session repairing it before qualifying. He will start 15th. Joe Gibbs Racing’s Ty Gibbs, who ended up fastest overall in practice, will start 10th on Sunday.

Gibbs fastest in practice

Ty Gibbs topped the leaderboard Saturday afternoon in practice at 181.733 mph over Hendrick Motorsports teammates William Byron (181.172 mph) and Chase Elliott (180.953 mph).

Denny Hamlin (180.741 mph) and Bubba Wallace (180.560 mph) rounded out the top five.

MORE: Practice results

Tyler Reddick (180.475 mph), Chase Briscoe (180.385 mph), Ross Chastain (180.288 mph), Kyle Larson (179.922 mph) and Christopher Bell (179.874 mph) completed the top 10.

Byron’s No. 24 Chevrolet had the best 5-, 10-, 15-, 20-, 25- and 30-lap averages. The only two playoff drivers outside of the top 10 were from Team Penske, as Ryan Blaney (179.104 mph) was 17th and Joey Logano (178.094 mph) was 28th.

LAS VEGAS – Dating back to mid-summer, William Byron’s 2025 statistics are full of waves. The bright spots include stretching his fuel tank at Iowa Speedway en route to his second victory of the season and clinching his first Regular Season Championship.

A deeper dive, however, shows more. Byron’s 11.17 average finish so far during the 2025 NASCAR Cup Series Playoffs ranks fourth among the eight remaining postseason drivers, despite having just one finish better than ninth in that span. That result was a third-place effort at arguably his worst circuit on the schedule at New Hampshire Motor Speedway.

RELATED: Las Vegas schedule | At-track photos

The No. 24 team’s highs haven’t been too high and its lows haven’t been too low — he’s playing on a level field. In the 17 events since Byron led a race-high 98 laps at Michigan International Speedway (only to run out of fuel in the closing laps), he’s led in just three races. He paced the field for a total of 147 laps in that span, with 141 coming in his Iowa triumph.

Byron isn’t concerned, however, shrugging off the possibility that the No. 24 team isn’t hitting its stride.

“All that is behind us,” Byron said Saturday at Las Vegas Motor Speedway. “We’ve done what we’ve needed to do. We haven’t done what we’ve wanted to do, but we’ve done what needs to be done to get to this point. The real race starts [in practice] and [Sunday]. Not really looking much at the past, but feel like we’re right where we need to be, at least from a preparation standpoint, going into Vegas. I’m pretty optimistic about today and tomorrow.”

Byron is a former winner at Las Vegas (spring 2023) and enters the weekend with five straight top-10 finishes in Sin City, the longest active streak in the series. With the points resetting, he drops to fourth, four points above Christopher Bell and the cutline.

The most recent intermediate track race at Kansas Speedway in the Round of 12 was disheartening for the No. 24 team. A late two-tire call by crew chief Rudy Fugle jumped Byron up the scoring pylon, gaining crucial track position and scoring a ninth-place effort. But the majority of the race was spent throwing “Hail Marys” to have a respectable showing.

The last 1.5-mile track before Kansas came at Charlotte Motor Speedway in May, when Byron crushed the field by winning the opening three stages and leading a career-high 283 laps. Ultimately, Ross Chastain got by in the closing laps to secure the victory.

After dissecting the Kansas performance, Byron feels like the No. 24 team can conquer Las Vegas (Sun., 5:30 p.m. ET, USA Network, HBO Max, PRN Radio, SiriusXM NASCAR Radio, NBC Sports App) and advance to the Championship 4 for the third consecutive season. He believes that it’s his best intermediate venue.

“This is a totally new beast now that we’re at the race track and see what we unload with,” Byron said.

Byron has pointed his way into the Championship 4 in each of the last two seasons. His average finish of 8.9 on 1.5-mile tracks is the best in the Next Gen era, according to Racing Insights. During Saturday’s practice session, Byron topped the scoring chart in five, 10, 15, 20, 25 and 30-lap averages. He’ll roll off fifth in Sunday’s 267-lapper after Joe Gibbs Racing swept the top three starting positions.

In each of the last two years, Christopher Bell has finished second in the Round of 8 opener at Las Vegas Motor Speedway.

The frustration in 2023 left him gutted after Kyle Larson beat him by 0.082 seconds. The disappointment he felt in 2024 after Joey Logano and the No. 22 team utilized a clutch fuel strategy call to earn the win by 0.662 seconds was summed up on his radio: “You’ve got to be [expletive] kidding me!”

MORE: Las Vegas schedule | Playoff standings

The memories of those defeats have lingered in the minds of Bell and crew chief Adam Stevens for the last year — particularly after missing the Championship 4 in 2024 in part due to his October loss in Sin City.

“That Vegas race we’ve been looking at and studying for basically since Vegas one earlier this year (in March),” Bell said ahead of last week’s race at the Charlotte Motor Speedway Roval. “Everyone knows how important that race is. It’s everything. I mean, we’ve seen it time and time again. That’s why the losses have been so heartbreaking. To come up close, to be so close to walking into that Championship 4 and not having it, everybody knows that Vegas is a super important race. Hopefully, we can dot our I’s, cross our T’s here at Charlotte, and then have that opportunity ahead of us next week.”

Indeed, it was mission accomplished for the No. 20 Joe Gibbs Racing team at Charlotte, where Bell took the checkered flag third and advanced to the Round of 8 for the fourth consecutive season. In two of the past three years, Bell has also qualified for the title race at Phoenix Raceway by locking into the Championship 4, a streak interrupted by last year’s ousting.

But what makes Vegas so important when it’s the first in a three-race round? That comes down to preparation in a championship pursuit. A win at Vegas for a playoff contender buys the successful party some cushion and mental relief from the stress of trying to lock in at the predictably unpredictable Talladega Superspeedway, in addition to short-track madness that could unfold at Martinsville Speedway.

Factor in an extra two weeks to focus preparations on the team’s car for Phoenix, and a Vegas win becomes priceless.

Bell finished 12th in the spring race at Vegas earlier this season, but he and his team have renewed reason to enter the Nevada 1.5-miler with confidence. At the most recent 1.5-mile track, Kansas Speedway, Bell was fighting for the lead when the white flag waved before ultimately placing third after leading 43 laps.

He described the team’s outlook as “very optimistic,” but a tinge of the anxiety that comes with this race’s results was also evident.

“I think Vegas races different (than Kansas),” Bell said. “It takes different things from your cars, but the general car potential and speed should be relevant. So yeah, I’m excited and obviously nervous, Vegas is a huge opportunity, and it seems like we’ve got the pace in our Camrys to go out there and do it.”

Stevens, Bell’s crew chief since the 2021 season, knows what it takes to win a championship, leading Kyle Busch to both of his titles in 2015 and 2019, respectively. He also knows how to get the most out of Bell.

“We know we can go there and be competitive,” Stevens told NASCAR.com. “Our intermediate stuff has really turned the corner here these last few weeks, and we feel like we’ll have the speed we need. And it’s up to us to execute the weekend and maximize our day.”

Sunday’s race (5:30 p.m. ET, USA Network, HBO Max, PRN Radio, SiriusXM NASCAR Radio, NBC Sports App) may not make or break Bell’s season, a campaign marked by four wins, 12 top fives, 19 top 10s and a series-best 11.7 average finish. But those 400 miles could determine whether Bell has a chance to win a championship — and that means everything.
