Sheldon Creed beat Sam Mayer on a restart with 13 laps to go Sunday at World Wide Technology Raceway to win his third Truck Series race of the season and a $100,000 bonus. Creed's victory pushed his bonus earnings to $150,000 this year in the Triple Truck Challenge. At the track outside of St. Louis, Creed battled with Todd Gilliland, who led a race-high 76 of the 160 laps. Moffitt tried to get around teammate Creed in the final restart but couldnt get his truck in position for the pass. The truck series next races Sunday at Darlington Raceway.

Busch won the NASCAR Trucks Series race at Homestead-Miami Speedway on Saturday night, his 58th career win on the circuit and his eighth victory in his last 10 trucks starts. Busch hadnt gone winless in three consecutive trucks starts since 2017. Brett Moffitt won the trucks race at Homestead in 2018 but didnt even get through 20 laps Saturday night, after he was part of a crash that also ended Zane Smiths race early. Elliott pitted, got four new tires to replace those ruined in the skid, and was part of the race within the race the battle for second behind Busch at the end. Ray Ciccarelli was in the race after a week where he made plenty of news for perhaps less-than-ideal reasons.

Marcus Lemonis, the CEO of Gander RV & Outdoors, which sponsors the Truck Series, agreed to match Harvicks pledge, bringing the total to $100,000 for pandemic relief. Elliott rubbed a little salt in the wound after the race, borrowing Buschs celebratory bow after the race. That is all.It was the first Truck Series race since Feb. 21 when Busch won at Las Vegas. Elliott, John Hunter Nemechek and Brennan Poole were the three full-time Cup drivers eligible to collect the $100,000 bounty. He followed up a fourth-place finish in the Coca-Cola 600 on Sunday by winning the Xfinity Series race on Monday in overtime after passing Austin Cindric on the final lap.
