Following in the footsteps of car owner Kasey Kahne, Sweet made a name for himself in the national open-wheel racing circuits. After being tapped to drive a part-time schedule for KKR in 2008, Sweet became a superstar in his own right in the USAC racing world with victories including the Belleville Midget Nationals, the Knoxville Midget Nationals and both the Sprint Car and Midget “Four Crown Nationals” at Eldora Speedway

Moving into the World of Outlaws ranks for KKR in 2013, he showed no signs of slowing down, winning the prestigious King’s Royal. 2014 was another breakthrough season for Sweet as he scored rookie-of-the-year honors and five feature wins. Sweet continued to be a threat on the World of Outlaws Series in 2015 with five wins, he earned eight wins in 2016, five in 2017 and 11 in 2018. Sweet and his NAPA AUTO PARTS team also finished second in the season point standings in back to back seasons in 2017 and 2018. Sweet earned the most coveted victory in sprint car racing in August of 2018 when he won the Knoxville Nationals along with its $150,000 payday – the biggest payout in all of sprint car racing.

In 2019 Sweet will once again compete for the World of Outlaws Sprint Car Series Championship with the backing of his crew chief, Eric Prutzman.
