Europe captain Padraig Harrington will choose three wild cards instead of four when his team defend the Ryder Cup at Whistling Straights next year.
Nine players will qualify automatically with points earned in tournaments from the BMW PGA Championship in September until the same event in 2020.
“In my experience, a player is more comfortable when he has qualified automatically,” said Harrington.
Europe thrashed the United States 17½-10½ to regain the Ryder Cup in 2018.
Thomas Bjorn, 2018 captain, used his wildcards to bring experienced players Paul Casey, Sergio Garcia, Ian Poulter and Henrik Stenson into the team.
Spaniard Garcia became the Ryder Cup’s leading points scorer at Le Golf National in France while Poulter beat world number one Dustin Johnson to help Europe reclaim the trophy.
