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 lowest tournament round score has been set at 63, with -180 for over, +700 for under and +210 for exactly 63. Winning margins of 1 (+210), 2 (+330), 3 (+550) or 4 or more (+300) are available, with +375 for the result to require a playoff. Odds for any golfer to make a Hole in One are -120 for Yes and -110 for No.
