Tee times for the first two rounds of The Open Championship at Royal Portrush were announced Tuesday.

It’s the final men’s major championship of the year, with the world’s best heading back to Northern Ireland after a triumphant return in 2019, the first since 1951.

The first three majors of the year saw Rory McIlroy complete the career Grand Slam at the Masters, world No. 1 Scottie Scheffler continue his torrid run by winning the PGA Championship and J.J. Spaun collect his maiden major victory at the U.S. Open.

Here's a look at some notable groupings for the first two rounds (all times in ET):

4:58 a.m./9:49 a.m.: Xander Schauffele, JJ Spaun, Jon Rahm

The defending Champion Golfer of the Year Schauffele returns to the spotlight with a chance to go back-to-back. Spaun, fresh off a stunning U.S. Open victory, aims to prove it was no fluke. And Rahm, newly energized and declaring he is swinging it the best in over a year, is hunting major number three.

5:09 a.m./10:00 a.m.: Shane Lowry, Collin Morikawa, Scottie Scheffler

Lowry is back where he became a national hero in 2019, looking for more Portrush magic. Morikawa, already a Champion Golfer, is chasing another slice of history. Meanwhile, world No. 1 Scheffler eyes his first claret jug, and a confirmation that his game travels on links.

9:59 a.m./4:58 a.m.: Jordan Spieth, Ludvig Åberg, Viktor Hovland

This trio could produce fireworks or chaos. Spieth is searching for consistency as he chases his second win at The Open. Åberg looks to add a major to his meteoric rise, and Hovland hopes to confirm his return to form.

10:10 a.m./5:09 a.m.: Rory McIlroy, Justin Thomas, Tommy Fleetwood

All eyes are on McIlroy as he returns to Portrush riding high after a stellar showing at the Genesis Scottish Open. Thomas seeks a bounce-back major moment at a venue where he’s surprisingly had his best The Open finish, and only in the top 30. Fleetwood, a fan favorite, hopes this could be the week he can finally deliver his long-awaited major breakthrough on a track he sets up well for.
