The Open Championship commences Thursday morning at Royal Portrush, highlighting the season’s final major in Northern Ireland. Fans in the U.S. may have to adjust their schedules for the early mornings or late nights, depending on their location, to keep up with their favorite athletes.

As usual, notable golfers will be paired together in the early rounds. Key matchups are expected on Thursday and Friday. The first notable tee time at 4:58 a.m. ET features Xander Schauffele, J.J. Spaun, and Jon Rahm, who is set to defend his title. Right after, at 5:09 a.m., the world No. 1 Scottie Scheffler will compete against Collin Morikawa and Shane Lowry. It’s essential to recall that Lowry won the last Open held at Royal Portrush.

In the afternoon slots, significant groups will begin their rounds in sequence, starting with Robert MacIntyre, Bryson DeChambeau, and Justin Rose at 9:48 a.m.; followed by Jordan Spieth, Ludvig Åberg, and Viktor Hovland at 9:59 a.m.; and concluding with Rory McIlroy, Justin Thomas, and Tommy Fleetwood teeing off at 10:10 a.m. McIlroy seeks his second major title of the season and aims to secure his first Open victory on home soil.
