What our Post expert thinks about the 2026 Open Championship
Scottie Scheffler won The Open last year and is the favorite to win it again this year, but his odds aren’t as far ahead of the field’s in a way we’ve been used to recently.
Scheffler has a 12 percent chance to win this weekend with Rory McIlroy just behind him at 9.8 percent. Matt Fitzpatrick (five percent), Tommy Fleetwood (4.5 percent), and John Rahm (four percent) round out the top five.
Must be 18 years or older and have a legal, U.S. residential address within the applicable state, D.C., or U.S. territories. Not available in AZ, IL, MA, MD, MI, MT, NV, and OH.
