It was a return six years in the making, and it was a return that perfectly encapsulated Rory McIlroy. Making the trek back to Royal Portrush for The Open Championship -- now as a career grand slam winner -- the Northern Irishman experienced a topsy-turvy day as the hard stuff came easy and the easy stuff came hard.

Will one of the world's top golfers win The Open Championship or will a long shot come from behind to capture the weekend? Here are the odds.

Rory McIlroy is returning to the iconic course 60 miles from his home, this time with a Masters green jacket. Lowry is in good form. World No. 1 Scottie Scheffler seems as powerful as ever. And now Jon Rahm is playing at an elite level again in time for a tough links test.

That's what is on the line this week at the 2025 Open Championship as Royal Portrush hosts the final major of the season in Northern Ireland. Returning to the par 71 for the first time since 2019 -- only the third time The Open has ever been held outside of Scotland or England -- the R&A has set up a tournament that will do its best to identify the man most equipped to deal with the elements and emotional toll one experiences across four rounds of major championship golf.
