Golf has the ability to unite people. Golf teaches you very good life lessons. It teaches you etiquette.""It teaches you how to play by the rules. It teaches you how to respect people. Sometimes this week we didn’t see that. So no, this should not be what is acceptable in the Ryder Cup. We will be making sure to say to our fans in Ireland in 2027 that what happened here this week is not acceptable," he added.The Europe team took the early lead in the game at the Bethpage Black Course. They had three points after the first-day matchups, which was increased to seven after the Saturday games.
