Brian Harman will begin his defence of the Claret Jug at Royal Troon alongside Viktor Hovland and Sahith Theegala.
The tee times for rounds one and two of The 152nd Open were announced on Tuesday, with Harman, the runaway champion at Royal Liverpool 12 months ago, grouped with FedEx Cup champion Hovland and world no.11 Theegala.
That trio will tee off at 9.58am on Thursday and 2.59pm on Friday, with Rory McIlroy, Max Homa and Tyrrell Hatton following them each day at 10.09am and 3.10pm.
World number one Scottie Scheffler is out on Thursday afternoon at 3.10pm with 2017 Open champion Jordan Spieth and 2022 runner-up Cameron Young. That trio is preceded at 2.59pm by two former Open winners in Shane Lowry and Cameron Smith, who will play with Matt Fitzpatrick.
American Justin Leonard, who won the 1997 Open at Royal Troon, will hit the opening tee shot at 6.35am. He is playing with 2004 Troon winner Todd Hamilton and Scottish qualifier Jack McDonald, whose grandad is an honorary member at the club.
