Open Championship returns to Royal Portrush in Northern Ireland, the site of Shane Lowry's triumph in 2019. As has been the case all year, the strong favorites entering the tournament are Scottie Scheffler (9/2) and Rory McIlroy (7-1).

That distinction belongs to world No. 1 and reigning PGA champion Scottie Scheffler. Masters — and Grand Slam — champ McIlroy is a clear second choice, with Jon Rahm, who has three top-10s in his last four Open starts, third.

The Open has had 28 different winners aged 38 or older all-time, the same number as the Masters and U.S. Open combined.
