After a dominant performance at the Irish Open, Jon Rahm now has the second-best British Open betting odds. Rahm is listed at 12/1, the same odds given to Jordan Spieth by Westgate Las Vegas Superbook. That’s a lot of respect for a 22-year-old who will make just his second start at The Open next week at Royal Birkdale.

Rahm finished T-59 in his tournament debut at Royal Troon last year. Dustin Johnson remains the tournament favourite at 10-to-1 odds. Other betting agencies list Rahm as high as 19/1, behind the likes of Johnson, Spieth and four-time Major champ Rory McIlroy.

In Vegas, McIlroy, reigning Masters champ Sergio Garcia and Rickie Fowler have the next-best odds (15/1), followed by a group at 20/1 that includes former World No.1 Jason Day, defending champ Henrik Stenson, and current World No.2 Hideki Matsuyama.

Also listed at 20/1 are a pair of players with connections to Royal Birkdale. Justin Rose finished T-4 at the venue in 1998 when he was a 17-year-old amateur. And red-hot Tommy Fleetwood, who won the French Open two weeks ago, and grew up just down the road from the Southport course.

Recent US Open winner Brooks Koepka fell to 30/1. Koepka decided to not play any events between the two majors. He’s joined at 30/1 by Adam Scott, who had three consecutive top-fives at The Open from 2012 to 2014.

Phil Mickelson, who finished T-20 at the Greenbrier Classic in his first event since parting ways with longtime caddy Jim “Bones” Mackay, is currently 40/1. The five-time Major champ’s last win anywhere came at the 2013 Open at Muirfield.
