Matt Crafton has reason to celebrate, and not just because he is close to winning the NASCAR Truck Series championship.

Crafton got a contract extension with ThorSport Racing on Thursday, ensuring him a 10th consecutive season with team owner Duke Thorson.

It's a fitting reward for Crafton considering he wrapped up his first series title last week at Phoenix. He has a 46-point lead over Ty Dillon heading into Friday night's season finale at Homestead-Miami Speedway. It's a big enough lead that Crafton only has to start the race to clinch the championship.

Crafton says he's endured "a lot of sleepless nights. You wake up at 2, 3 in the morning asking, 'How can I lose this thing?'"

Realistically, he can't.
