Few drivers have been on as strong of a run on the NASCAR Cup Series as Martin Truex Jr., who has a win and three top-five finishes in his last four races. He might have even been more successful had it not been for a crash that spoiled his race at Darlington, where he started on the pole. After this recent run, he is 15-2 in the latest 2023 Grant Park 220 odds listed on Caesars Sportsbook.

Truex's recent win came on a road course at Sonoma, which isn't a direct comparison to what lies ahead in NASCAR at Chicago, but is certainly closer than traditional oval-style speedways. Regardless, the competition will be tough, as he'll be racing against other 2023 Grant Park 220 contenders like Kyle Larson (15-2), Tyler Reddick (13-2) and Chase Elliott (11-2). Before scouring the 2023 Grant Park 220 starting lineup and making any 2023 NASCAR at Chicago predictions, be sure to see the latest 2023 NASCAR Chicago Street Race picks from SportsLine's proven NASCAR model.

Developed by daily Fantasy pro and SportsLine predictive data engineer Mike McClure, this proprietary NASCAR prediction model simulates every race 10,000 times, taking into account factors such as track history and recent results.

McClure's model is off to a red-hot start this season, already nailing Martin Truex Jr.'s Clash win (20-1), Joey Logano's Duel win (8-1), Kyle Busch's Fontana victory (10-1), Denny Hamlin's triumph in Kansas (6-1) and Kyle Larson's wins at Martinsville (6-1) and the NASCAR All-Star Race (13-2). In Austin, it listed Tyler Reddick as one of its best values and he went on to win for a 10-1 payout. It also impressively nailed five of Kyle Larson's wins during his historic season in 2021. 

All told, the model has nailed a whopping 12 winners since 2021. Anyone who followed its lead on those NASCAR picks saw huge returns.

Now, the model simulated the 2023 Grant Park 220 10,000 times. Head to SportsLine to see the complete projected 2023 Grant Park 220 leaderboard.

Top 2023 Grant Park 220 predictions

One surprise: the model is high on William Byron, even though he is a 15-1 longshot in the latest 2023 NASCAR at Chicago odds. Deciphering which driver is going to have the most success at NASCAR's first street race is anyone's guess, but Byron is a target for anyone looking for a huge payday. Byron has fared well on road courses, and should be well equipped to challenge for the win.

Earlier this season, Byron finished fifth at Circuit of the Americas and 14th at Sonoma earlier this month. In those two races, Byron finished with the fifth-highest positions finished above expected rating among all drivers (17.10). Byron has already won three times this season, and considering how well he's driven overall and on road courses this year, he'll be a threat to win in Chicago. See who else to back at SportsLine.

And a massive shocker: Martin Truex Jr., one of the Vegas favorites at 7-1, stumbles big-time and barely cracks the top 10. There are far better values in the 2023 Grant Park 220 starting lineup, according to the model. The current points leader has scored a couple of victories this year, including a win at Sonoma.

But he was 17th in the previous road race at Circuit of the Americas and failed to crack the top 10 in the last five road races of the 2022 season. He's also had eight finishes outside the top 10 so far this season is coming off a season where he missed the playoffs entirely in 2022. See which other drivers to avoid at SportsLine.
