OK ... so, here goes.
When Chad Green beat Matt Hagan in Las Vegas in 2021, Hagan was the reigning champion (Hagan won in 2020), and it was the first round-win for Green. And, to date, his only round-win.
Including Green, there have been 14 drivers who won their first round against the reigning world champion: four in Funny Car, seven in Pro Stock, and three in Pro Stock Motorcycle. I haven’t found any in the Top Fuel class. Here's the complete list:
