Mike took home $1 million when he won first prize at the World Series of Poker Circuit Tournament of Champions.
He got through 17 hours of the final table, and beat out some of the world's best poker pros at the Rio Hotel and Casino in Las Vegas.
Three time WSOP bracelet winner Daniel Negreanu came in second place, while Mike Matusow came in third.
Sexton won his first WSOP bracelet in 1989, so this was his first big win in 17 years.
He also plans to donate half his winnings to various charities.
Congratulations Mike!
