After winning the PGA’s FedEx Cup and its $10 million prize, 28-year old professional golfer Billy Horschel gave his caddie a $1 million tip.

It is typical for professional golfers to tip their caddies 10% of winnings for a particular tournament, but the FedEx Cup is a prize based on season-long points rather than a single tournament. As such, 10% of the $10 million prize was not automatic.

The caddie told Golfweek:

“Shock, happiness, joy,” said Fugitt, who will set up college funds for his two children. “You have such a wide range of emotions.”
