The 2025 Open Championship gets underway Thursday at 1:35 a.m. ET at Royal Portrush in Northern Ireland.
Xander Schauffele is the defending champion, while Shane Lowry won the last time the Open was played on the course in 2019.
Scottie Scheffler and Rory McIlroy head in No. 1 and No. 2 in the world and winners of two of the year's first three majors.
Will the big names battle it out at the top? What long shots could contend? And how will Royal Portrush play over the next four days?
