The NASCAR Cup Series heads to Martinsville Speedway this week for the 2024 Xfinity 500, which is the final opportunity to claim a spot in the championship race. Kyle Larson and Denny Hamlin find themselves on the wrong side of the cutoff line after Tyler Reddick secured his spot last week. Hamlin and Larson are the +500 (risk $100 to win $500) co-favorites in the 2024 Xfinity 500 odds, followed by Ryan Blaney (+550), Chase Elliott (+850) and William Byron (+1000). Sunday's race is set to begin at 2 p.m. ET. 

Before entering any 2024 Xfinity 500 props or NASCAR picks on sites like PrizePicks, DraftKings Pick6, Sleeper Fantasy, and Underdog Fantasy, be sure to see what elite expert auto racing handicappers Phil Bobbitt and Steve Greco have to say.

Bobbitt and Greco built a predictive engine that consistently beats the books. They find huge value and aren't afraid of volume. Over the past three years, their followers are up more than $26,100 on $100 plays. Last season, they called +4000 longshot Michael McDowell winning the Verizon 200 at the Brickyard and Blaney to win the NASCAR Cup Series Championship at +3000. 

The duo began 2024 by calling Hamlin to win the Clash at the Coliseum at +1100 and hit on three of its four top-five wagers. Three weeks later at Atlanta, they predicted Daniel Suarez's victory at +3500 and were 10-2 on matchup plays. They went 9-3 on head-to-head plays in the Toyota Owners 400 in March, going +13.58 units in that article alone. Their 2024 NASCAR All-Star Race preview nailed Joey Logano at +1100 and went 4-0 in matchup picks, and they hit Austin Cindric at +2800 in the Enjoy Illinois 300. They also nailed Ross Chastain as a 30-1 longshot in the Hollywood Casino 400. Anyone following Bobbitt and Greco has seen HUGE returns!

For the 2024 Xfinity 500, we can tell you Bobbitt and Greco are backing Martin Truex Jr. to finish ahead of Joey Logano in a head-to-head prop that pays +115. Truex has three wins in his last 10 starts at this track, and he led 47 combined laps in the two races at Martinsville last year. Logano has not won at Martinsville since the 2018 playoff race, so Bobbitt and Greco are backing Truex in this head-to-head prop.      

Bobbitt and Greco have locked in more NASCAR props, finishing positions, and outright bets, including a driver who is a massive 100-1 longshot to win it all! You ABSOLUTELY need to see their picks before locking in any NASCAR picks of your own.
