Two weeks after winning the Indianapolis 500, Helio Castroneves was likely hoping for a better finish than the fourth place he got in the Camping World SRX Series' inaugural race. After the opening weekend, the four-time Indy 500 winner sits at sixth place in the 2021 SRX Series standings entering Saturday's event at Knoxville Raceway in Iowa. The IndyCar legend is one of the biggest names in co-founder Tony Stewart's racing venture, but he may look like a fish out of water at SRX Series at Knoxville. The track is a ½-mile dirt oval and Castroneves says the last time he raced on dirt, he was an 8-year old.

The green flag for the SRX Series at Knoxville will drop at 8 p.m. ET and will be broadcast live on CBS and Paramount+. Castroneves is listed at 4-1 in the latest SRX Series at Knoxville odds courtesy of SportsLine. Stewart is the 2-1 favorite, while other contenders include Brian Brown (5-2) and Scott Bloomquist (3-1). Before scouring the Camping World SRX Series at Knoxville starting lineup and making any Superstar Racing Experience predictions, be sure to see the latest SRX Series at Knoxville picks from SportsLine's proven projection model

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

In the 2021 NASCAR  season, the model has correctly predicted at least seven top-10 finishers in seven of the last 13 races. And in April, McClure nailed Martin Truex Jr. to win at Martinsville for a strong 3-1 payout. Last week, the model nailed Kyle Larson to win the 2021 NASCAR All-Star Race for a 5-2 payout. Anyone who has followed its lead on those plays has seen some huge returns.

Now, the model simulated the SRX Series Knoxville race 10,000 times. Head to SportsLine to see the complete projected SRX Series at Knoxville leaderboard.

Top Camping World SRX Series at Knoxville predictions

One of the SRX picks from the model: Bobby Labonte, who is going off at 5-1 in the 2021 SRX Series at Knoxville odds, makes a strong run at the checkered flag. He's a target for anyone looking for a huge payday. The NASCAR Hall of Famer finished runner-up in Heat 1 last week and fourth in the Feature Race. He sits at fourth in the SRX Series standings, but only one driver ahead of him will be competing at Knoxville.

Labonte compared racing on dirt in the SRX Series to the trucks he steered as a part-timer on the Camping World Truck Series. Labonte competed 10 times on that circuit and had one win along with three other top-three finishes. He also co-founded Longhorn Chassis, which manufactures dirt late models, so he knows what makes a car dynamic on this surface. Labonte described racing on dirt as "a big challenge probably for everybody" but he has a leg up in terms of experience and knowledge on the surface.

And a surprise: Brian Brown, one of the favorites at 5-2, stumbles and doesn't finish in the top three. There are far better values in this loaded Superstar Racing Experience field. Brown is a veteran of Knoxville Raceway and garnered two top-10s there last week with the World of Outlaws. He is a four-time track champion, but all of that success came in a sprint car, so this will be something entirely new for him.

In addition to driving a different kind of car, Brown is at a disadvantage as a part-time driver on the SRX Series. That means he didn't compete in last week's inaugural event, so he didn't get a feel for the vehicle itself, and the type of racing that will go down on the track. 

Nine of the 12 drivers for SRX Series at Knoxville raced last week at Stafford, so Brown is one of the few who will have a steeper learning curve. With the race being just 100 laps, time isn't on his side to pick things up quickly which is a big reason the model is fading him for your SRX Series at Knoxville bets.
