It won't go down in history like Rory McIlroy's opening tee shot at Royal Portrush in 2019, but K.J. Choi's first swipe at the ball on Thursday at the Open Championship may have been worse. And his ball stayed in bounds.

The first day off the 153rd Open Championship has officially started at Royal Portrush. Around 280,000 spectators from around the world are set to attend the tournament on the North Coast to see the very best golfers in the world battle for the famous Claret Jug.

Here are the groups that will be playing together in Round 1 of the 2025 Open Championship, plus their tee times. Coverage of the 2025 Open Championship can be found on NBC, USA Network, Peacock, and Golf Channel. Anyone looking to stream the event can do so with Fubo.
