The winner of the 2019 AT&T Byron Nelson gets a lot of money, and the AT&T Byron Nelson first-place payout is commensurate with winning on the PGA Tour
The 2019 AT&T Byron Nelson purse is $7.9 million, an increase of $200,000 from the prior year. The PGA Tour pays 18 percent of the total purse to the winner, so the 2019 AT&T Byron Nelson winner will earn $1,422,000 as the first-place payout.
In 2018, Aaron Wise won $1,390,000 as the AT&T Byron Nelson winner's check from an $7.7 million purse.
The AT&T Byron Nelson does not have the biggest purse in professional golf. That belongs to The Players Championship, which has a $12.5 million purse. The US Open is second best with a $12 million purse.
However, the tournament with the highest first-place payout in all of professional golf now belongs to the European Tour. The winner of the season-ending 2019 DP World Tour Championship on the European Tour will win $3,000,000, making it the biggest first-place payout in all of golf.
