JR Motorsports has dominated the 2025 NASCAR Xfinity Series season, and for the second time in four years, the organization has filled three of the four Championship 4 spots. Even after 5,123 laps in 2025, storylines are plentiful entering Saturday’s season finale at Phoenix Raceway (7:30 p.m. ET, The CW, MRN Radio, SiriusXM NASCAR Radio), with it all coming down to the final 200 circuits.
The youth movement took over in 2025, with half of the Championship 4 drivers (Zilisch, Kvapil) concluding their rookie campaign. Friendships will be tested; sophomore Jesse Love is looking to upset the dominant Connor Zilisch, who’s one of Love’s best friends away from competition.

Meanwhile, a familiar foe in Justin Allgaier returns for his eighth Championship 4 appearance. The Illinois native is looking to defend his 2024 championship and become the first repeat titleholder since Tyler Reddick in 2018 and 2019.
Let’s preview each championship-contending driver and where they stand heading to Phoenix.
Connor Zilisch
2025 regular-season finish: 1st
Playoff seed: 1st
What is there to say about Zilisch that hasn’t already been said? The 19-year-old prodigy has won double-digit races (10), led laps in 20 straight starts and set the new series record for consecutive top five finishes with 18, spanning from Charlotte Motor Speedway in May to Las Vegas Motor Speedway in October. (His 2.1 average finish in that span is best in series history, too.) He became the first driver in series history to win eight events in an 11-race span.
This is Zilisch’s lone shot at winning an Xfinity title as he will transition to the Cup Series for Trackhouse Racing in 2026. Phoenix is one of the few venues where he’s made multiple Xfinity starts, including a fourth-place finish in the championship race last year. In the spring race, he led two laps before dropping to 16th in the finishing order.
“We’ve been able to work on [Phoenix] for the last three or four weeks, assuming we were going to make it,” Zilisch said before his laps-led streak ended at Martinsville Speedway. “We’ve been doing a lot to make sure that we are better going back from the spring and that we execute the day and make the most of it. It’s been good so far, and I feel like we’ve gotten to a good spot, preparing myself for it.”
Justin Allgaier
2025 regular-season finish: 2nd
Playoff seed: 2nd
Coming off one of the better feel-good moments in series history last year in the “Valley of the Sun,” Allgaier is looking to play spoiler this weekend at Phoenix. The No. 7 team has three victories in 2025, with the last coming five months ago at Nashville Superspeedway.
The No. 7 team leads the league in stage wins in 2025 with 14 and is 13 laps shy of tying JRM teammate Zilisch for having the most laps led (986 vs. 973). Allgaier has finished races better than in his championship-winning season, already having four more top fives in 2025 (14) compared to 2024 (10). Along with Zilisch, Allgaier had a stress-free Martinsville, having secured a Championship 4 berth on points the previous week at Talladega Superspeedway.
Despite having seven fewer wins than the No. 88 team in 2025, Allgaier should probably be considered the favorite on Saturday evening. He has a pair of victories, 12 top-five and 20 top-10 finishes in 30 Phoenix starts. He has six times the experience at the 1-mile track than his fellow Championship 4 contestants combined.
“We’ve stayed working on Phoenix,” Allgaier said at Martinsville. “We’ve been lucky enough to focus on what we’ve needed to focus on and go to Phoenix. It’s cool for me because all four cars at JR Motorsports are going back with stuff that I’ve run before. All the setups are derived from where we’ve been at, and I know the strengths and weaknesses of all the different options of what we do as a company.”
Jesse Love
2025 regular-season finish: 4th
Playoff seed: 4th
As Love mentioned to Jayski.com in August, he has been ridiculously consistent in 2025. Nothing overly flashy, though, for the No. 2 Richard Childress Racing team, which has led nearly half of its 262 laps led in 2025 at superspeedways (129). Phoenix by no means correlates to superspeedway racing.
Despite the No. 2 team’s infrequency of pacing the field, Love’s 11.4 average finish ranks second among full-time drivers, trailing Zilisch’s 8.2. He also has the second-most top 10s in 2025 with 21, ranking just behind Zillich’s 22.
The elephant in the room, however, is Phoenix. Love is sneaky good at the venue and was leading during double overtime in last year’s championship race. He was used up by Allgaier on the restart, dropping to sixth. In three Xfinity starts at Phoenix, he has never finished worse than ninth.
“I know that we’ll be good at Phoenix,” Love said after a disappointing 23rd-place effort at Martinsville. “I know it’s one of my best race tracks. I have a lot of laps there. I put a lot of effort into it. I pride myself racing for championships and being the steady shoe. Phoenix has always rewarded that.”
Carson Kvapil
2025 regular-season finish: 7th
Playoff seed: 8th
Kvapil is aiming to follow the Daniel Hemric playbook in 2021, winning his first race en route to being crowned champion.
The short-track ace has transitioned to full-time NASCAR racing in 2025, but is racing for his livelihood as JRM announced last month that he won’t return to the team in a full-time capacity in 2026. While the No. 1 team has yet to visit Victory Lane, Kvapil has seven top-five and 14 top-10 finishes, on par with fellow rookies Taylor Gray and Christian Eckes. Among the Championship 4 drivers, though, he ranks the lowest in wins, top fives, top 10s, average finish (13.8) and laps led (104; 40 of those came last weekend at Martinsville).
The positive news for Kvapil is that Phoenix doesn’t measure 1.5 miles, which he believes is the biggest area of growth he still needs to make. He has just one Phoenix attempt on his resume, finishing 26th in the spring with multiple mechanical woes.
“I feel OK. I feel like there are tracks that I’d rather go to, right?” Kvapil said. “I feel like we didn’t have that great of a car and had some pretty big mechanical troubles at Phoenix earlier in the year, and we were still running 10th before we blew a rotor. Honestly, I feel like there’s no reason we can’t go outrun these guys and try to win a championship.”
