Gateway Comes Down to 6 Cars

6 cars win 71% of our 10,000 runs of Sunday's Enjoy Illinois 300, and they come from 2 shops: Denny Hamlin, Christopher Bell, Chase Briscoe and Ty Gibbs in the Joe Gibbs Toyotas, Ryan Blaney and Joey Logano in the Penske Fords. Hamlin projects to finish 5th, the best in the field, Gibbs 8th, the worst of the six, and nobody outside them projects better than 9th, at a track where every Cup winner has started inside the top 7.

The market has read the same table and then priced in one more name. DraftKings Sportsbook, as of Friday afternoon, had Bell the favorite at +400 and Kyle Larson at +750, ahead of Briscoe at +1000 and Gibbs at +1200. Our sim gives Larson a 3.3% win chance, less than half of Briscoe's 7.8%. Larson can bolt from anywhere, and we would still rather have the Toyota at the longer price.

What our numbers say

Why Saturday decides it

The top of the table is flat, 6 drivers inside 3.5 spots of each other on average finish, and that is a table Saturday's qualifying will reorder. Since the current car arrived in 2022, only 2 ovals on the Cup schedule, Martinsville and Phoenix, tie a driver's finish more tightly to where he started than Gateway does, and everything else above it on that list is a road course.

The reason is that cars do not move much once the green flag drops. Gateway averages 72.1 green-flag passes per driver per race, 9th fewest of the 31 tracks in the current era, against 117.0 at the rest. What passing there is belongs to the same people every week. The 7 best net passers in Cup this season all gain positions at Gateway, and Tyler Reddick, Blaney, Larson and Bell each net 15 or more green-flag passes per race there.

Put the two together and the bet for Sunday, once the grid is set, is a driver who qualifies inside the top 12 and passes cars, in the top-5 and top-10 markets. Blaney starts 9.9 on average this season and nets 11.3 passes per race, the best in Cup, and Gibbs is the 2nd best passer from a similar starting spot. Bell is the one to watch on Saturday. The passing is there, but he has qualified 14.8 on average this season, and at Gateway his average start is 8.0.

The Penske half

Logano has finished inside the top 5 in all 4 of his Cup starts at Gateway, and his 3.5 average finish there sits against a field average of 17.9. The next best mark among Sunday's entries is Bell's 8.5, a full 5 spots back. His win came in the inaugural race from 7th on the grid, the only Gateway win not taken from the front row.

The season is the part that does not fit. His 16.9 average finish is the worst of the six, and it is why he projects to finish 7th. Our sim still gives him a 14.2% win chance. Both of his 2026 wins came on flat tracks, at North Wilkesboro and Richmond, and he arrives on the longest active Gateway top-10 streak in the field, 4 races.

Across 2025 and 2026 he averages 11.1 on flat tracks against 18.3 everywhere else. We expect the mean reversion to show up Sunday. At +700 he is the only one of the 4 favorites whose price pays better than our sim's win chance calls for, and that is the win bet we like.

Blaney is the Penske car the market and our sim agree on, and the one whose Gateway record is missing a result. He has a 9.5 average and 120 laps led across 4 starts there, the most laps led of anyone entered, and no win. His 6.0 average running position at Gateway is the best of anyone entered.

The rest of his sheet is why the sim likes him. Across 2025 and 2026 he averages 7.2 on flat tracks, the biggest flat-track edge of anyone entered at 8.7 spots. He arrives on the best 10-race stretch of anybody in the field, 399 points, with a win at New Hampshire inside it. Our sim gives him an 83% top-10 chance.

The Gibbs half

Hamlin holds the top of our table, with the best win chance in the field at 17.0% and the best top-10 chance at 86%. His last 3 Gateway starts read 2nd, 2nd and a win from the pole, and the only thing holding his average at 9.8 is a 34th in his first visit. At +425 the market is paying for all of that, and it is hard to argue.

The season backs it up. His 8.6 average finish is the best in Cup, and he has run 3,504 laps inside the top 5 this year, close to half of every lap he has turned. His 6.6 average on flat tracks across 2025 and 2026 is the best of anyone entered.

Bell is the favorite, and the market is paying for consistency plus a win. His average across 4 Gateway starts trails only Logano, and his first win of the season came at Darlington on Sunday after 7 runner-up finishes. What +400 does not include is a top 5 at Gateway. He has never had one there, and the day he led 80 laps in 2024 he finished 7th. Our sim gives him the 2nd best win chance in the field at 14.4%, and a top-10 chance behind Hamlin, Blaney and Gibbs.

Briscoe and Gibbs are closer to the favorites than their prices say. Briscoe's 19.3 average across 4 Gateway starts is the worst of the six, and the early visits are the reason. Over his last 2 he averages 9.5, including a 2nd last year in his first Gateway start with a Gibbs car. Our sim gives him a 7.8% win chance.

Gibbs has a 13.7 average across 3 Gateway starts and is the 2nd best net passer in Cup this season, behind only Blaney. He ran 2nd at Darlington on Sunday and won at Iowa, another flat track, this summer. Our sim gives him a 68% top-10 chance, better than Bell's, and he is the longest price of the six.

The one name our sim rates higher than we do is Reddick, at a 7.6% win chance, more than Gibbs. The reason is passing: 22.0 net green-flag passes per race at Gateway, the most in the field. The finishes do not follow. He averages 17.8 there, and his flat-track split across 2025 and 2026, 17.9 against 11.3 everywhere else, is the worst of anyone entered Sunday. Back-to-back 3rds at Daytona and Darlington say the slump is over, but this type of track is just not his specialty.

The bet outside the six

William Byron is the driver everybody has stopped talking about, and we think that is a mistake in the top-5 and top-10 markets. His season reads badly, no wins and a 16.9 average, and his 37th at Darlington on Sunday came late, while he was running inside the top 10 on both pace and position. The No. 24 also has one of the fastest crews on pit road.

The case for Sunday is the track type and the passing. Across 2025 and 2026 he averages 13.2 on flat tracks, 3.5 spots better than everywhere else, and he nets 14.5 green-flag passes per race at Gateway, so a mid-pack qualifying spot is not the end of his day. He projects to finish 11th. Top 5, top 10 and plus-money head-to-heads are where we would spend it, not the win market.

If you want a hedge inside the same shop, Larson to finish as the top Chevrolet is the one we like. Our sim has him 2 spots ahead of Byron, with Chase Elliott 1 more back and Carson Hocevar projected to finish 18th, and Larson has led 758 laps this season without a win. Hocevar, with the week he is having, is the one we would leave alone.

The DFS read

For DraftKings players, Gateway is a place to spread the laps-led money. Laps led and fastest laps together make up 14.0% of all DraftKings points in the last 2 Gateway races, against 15.6% at every other Cup track since 2015, and our sim splits what pool there is 4 ways, with nobody projected past 30 laps led. Fastest laps are the exception: the top car at Gateway takes 34.6% of them on average against 20.2% across Cup.

Ownership, the share of DraftKings lineups expected to hold a driver, is where the six get expensive. Bell is the chalk of the slate at a projected 45.5% ownership and the top salary, $11,000, with Blaney next at 39.6%. The leverage, meaning the driver whose lineup share runs well behind his chances, is Gibbs: $9,200, 25.7% projected ownership, and a 68% top-10 chance that beats Bell's. In a tournament, that is the Toyota to build around.

Saturday: Allgaier and the O'Reilly field

Justin Allgaier projects to finish 4th in Saturday's Nu Way 225, and nobody else on our O'Reilly table projects better than 7th. He wins 30.5% of our runs and finishes inside the top 10 in 88% of them, both the best marks in the field by a wide margin. The price is the top salary on the slate, $12,000, and a projected ownership of 45.0%, which is the O'Reilly version of the Bell problem.

The next best win chance belongs to Sheldon Creed at 11.6%. He has won at Gateway twice in the Truck Series, and nobody entered Saturday has won there more. Austin Hill, who runs both races this weekend, carries the 3rd best win chance at 8.4%. The one to think twice about is Carson Kvapil: the 2nd highest salary on the slate, 38.6% projected ownership, and a win chance of 4.9% that ranks 6th in the field.

The Nu Way 225 Powered by Bobcat and Sauced by Blues Hog goes green Saturday, Sep 12 at 7:30 pm ET on The CW, streaming on DIRECTV. O'Reilly Series practice runs Saturday, Sep 12 at 1:00 pm ET, with qualifying right after it.

The Enjoy Illinois 300 goes green Sunday, Sep 13 at 3:00 pm ET on USA Network. Cup practice runs Saturday, Sep 12 at 3:30 pm ET, with qualifying right after it. Our table comes from a sim run before anybody has turned a lap. At Gateway the grid is most of the argument, so Saturday's qualifying will move it more than it does most weeks, and the projections page re-runs the race the moment the grid is set.
