The Open Championship Favorites & Contenders 

As has been the case in previous majors this year, Rory McIlroy, Scottie Scheffler, and Jon Rahm can all be found at the top of the Open Championship oddsboard at BetMGM.  

Rory McIlroy +5000

McIlroy, who finished runner-up to Wyndham Clark in the recent US Open, is the betting favorite to win this year’s Open Championship. He’s coming in strong off a victory in this past weekend’s Genesis Scottish Open.

Notably, though, he hasn’t won a major tournament since 2014 (PGA Championship at Valhalla). The Northern Irishman did win the 2014 Open Championship at Royal Liverpool, so he might be a good horse for the course this time around.

Scottie Scheffler

Scheffler showed out in his first three majors of the year with a T-10 at The Masters, a T-2 at the PGA Championship, and a solo third in the US Open. He also recorded wins at the Players Championship and WM Phoenix Open.

Jon Rahm +700

Rahm has arguably been the best player in golf over the past year, with four victories including his first win at The Masters in April. Among the top-ranked players in the world, he was the only one not to tee it up in Scotland last weekend.

Rahm’s best Open Championship finish came in 2021 when he was T-3 at Royal St. George’s.   

Cameron Smith +50000

Smith is the defending British Open champion after winning at St. Andrews last year. He’s coming into this year’s Open Championship in great form after winning the recent LIV Golf London event.

Brooks Koepka

Koepka is at his best in major tournaments with five career wins. He won the 2023 PGA Championship after starting the year with a T-2 at The Masters. Koepka finished T-17 in last month’s US Open.

British Open Value Picks

The Open betting odds offer some value as you move down the oddsboard. It’s always fun to target players at higher odds that are capable of winning the British Open, and providing a nice payday.

Justin Rose

Justin Rose is a great value at these 2023 British Open odds. The Englishman has two top-fives and three top-10s on his Open Championship resume. His best finish (T-2) came at Carnoustie in 2018.

Rose won the AT&T Pebble Beach Pro-Am earlier this year.

Jason Day +2800

Jason Day’s return to prominence culminated with a recent victory at the AT&T Byron Nelson. His best Open Championship finish (T-4) came at St. Andrews in 2015.

Here’s a look at more British Open sleeper picks to bet before the tourney tees off on Thursday.

How to Bet on Open Championship Odds in 2023

One important part of betting on the Open Championship is making sure you wager early. The tournament tees off in the early morning here in the US (like 3 a.m. early), so gets your bets in by late Wednesday night.

Betting on golf, specifically on the majors, is different from betting on baseball, football, and other major sports. First and foremost, it isn’t a team sport; there isn’t a “Team A” or a “Team B.” It’s one player against the rest of the field.  

It is always a challenge to pick the outright winner of a golf tournament. But the good news is there are plenty of other ways to bet on the Open Championship.

The Open Championship also offers an extensive list of prop bets. “Will there be a hole-in-one?” or “will there be a playoff?” are good examples.

You can also wager on head-to-head matchup bets on one player to beat the other. Another example of Open Championship prop bets? Betting on top finishers by country.
