The first-round leader (FRL) market is one of the best bangs for your buck in all of sports betting, and there’s no better tournament for FRL bettors than the Open Championship.
The wind, rain, and unique courses make the British Open a carnival of chaos, and when you shrink it down to just 18 holes the playing field gets leveled even more, which leads to some surprising names at the top of the leaderboard after Round 1.
Just look at the players who paced the field after 18 holes at the last five iterations of the Open:

As those names suggest, this is not the place – or the market – where you want to be spending your bankroll on players at the top of the board.
Instead, it behooves you to take some shots and sprinkle some sleepers being offered at big prices.

2025 Open Championship First-Round Leader picks
Marco Penge 80/1 (FanDuel)
Although not a household name on this side of the Pond, Marco Penge is starting to rack up impressive results on the DP World Tour.
The Englishman won the Hainan Classic at the end of April, finished T11 at the BMW International Open two weeks ago and then was a runner-up (with Rory McIlroy) at the Scottish Open last week.
Penge is someone to consider across all markets, but we’ll back him to get off the blocks hot Thursday.

Lucas Glover 140/1 (bet365)
There’s no right or wrong way to handicap the first-round leader market. It’s nearly impossible to predict.
But it doesn’t hurt that Lucas Glover is coming off back-to-back top-10 finishes at the Travelers Championship and John Deere Classic.
Padraig Harrington 500/1 (Caesars Sportsbook)
Glover has plenty of experience in this event, so he shouldn’t be overwhelmed by whatever Royal Portrush throws at him this weekend.
A two-time Open Champion, Padraig Harrington is well past his prime. That said, the Irishman still has it in his locker to go low for 18 holes in conditions that will be to his liking.
The 53-year-old should come into the week buoyed with confidence after winning the U.S. Senior Open at the end of June, and he made the cut at last week’s Scottish Open.

Lee Westwood 500/1 (DraftKings)
Like Harrington, Lee Westwood is into his 50s and well beyond his prime. However, the 52-year-old Englishman is playing some decent stuff on LIV and he finished T4 at Royal Portrush back in 2019.
That’s enough to get me in at this price.
