Luke Donald couldn’t help but bring it up again.

The European captain made multiple not-so-subtle jabs at the U.S. team during the Ryder Cup opening ceremony on Wednesday at Bethpage Black, hitting the Americans for getting paid to compete in the event while his team is doing it for free.

“It is not about prize money or world ranking points. It’s about pride,” Donald said while addressing the crowd during the opening ceremony. “It’s about representing your flag, your shirts and the legacy you leave behind.”

Minutes later, Donald brought it up again.

“We are fueled by something money cannot buy: Purpose, brotherhood and a responsibility to honor those who came before us, while inspiring those whose time is yet to come,” he said.

Captain Keegan Bradley and all 12 members of the U.S. team are receiving $500,000 each from the PGA of America for their participation in the Ryder Cup this year. That figure was increased this season for the first time since the pay-for-play model was introduced in 1999. Previously, golfers received $200,000 to donate to a charity of their choice.

This fall, golfers will donate $300,000 to charity. The remaining $200,000 is considered a stipend for them to do with what they wish. Bradley has said that he plans to donate all $500,000 that he receives to charity, and some players will do the same.

“I think that’s a personal decision,” Bradley said on Monday. “I don’t donate to charities to publicize what we’re doing. These guys on our team are incredible people, and they do a lot of incredible things with charity dollars and with their foundations. A lot of them aren’t comfortable sharing that sort of information, and I feel the same way.”

While the donations will undoubtedly do a lot of good, the stipend has drawn plenty of criticism from the Europeans. Rory McIlroy even said last year that he’d pay for the chance to play in the Ryder Cup, if that was necessary.

Donald’s comments on Wednesday echoed what he said on Monday afternoon. He confirmed then that the entire European team rejected the idea that they should be getting paid a long time ago.

“This isn’t a week to get paid,” Donald said Monday, via SkySports. “We have such strong purpose in this team, in what we play for, and to be honest we reinvest some of that money back into the experience of these guys.

“I feel like, if you have those experiences that you remember for the rest of your life, that’s worth more than a couple hundred thousand dollars in the back of your pocket.”

The Ryder Cup will officially kick off on Friday morning with a series of foursomes matches. The Europeans, who have won eight of the last 11 Ryder Cups, have lost the previous two on American soil.
