TROON, Scotland — Cut day at the British Open brings with it plenty of stress and anxiety as players well down the leader board are still keeping a close eye on the scores to figure out where they stand, and whether the numbers they’re posting will be low enough to play on the weekend. Exactly where that will fall at Royal Troon is made more uncertain by a weather forecast that calls for some wind and rain on Friday that could change the equation.

The rules for who makes the cut at the Open are similar to those at the PGA Championship: low 70 players and ties advance to play all four rounds. This differs from the U.S. Open, which makes the cut at low 60 and ties, and the Masters, which keeps the low 50 and ties around on the weekend. And there is no 10-stroke rule in effect to help determine the British Open cut.

All this is, of course, particularly relevant for handful of the game’s more familiar names, including the two central figures at the most recent major, the U.S. Open at Pinehurst. Both winner Bryson DeChambeau (76) and runner-up Rory McIlroy (78) have work to do Friday at Troon if they hope to find themselves merely playing on the weekend let alone back in contention.

Other notables that will be in search of a low score to keep their major season going include: Max Homa (76), Will Zalatoris (76), Tommy Fleetwood (76), Sahith Theegala (77), Wyndham Clark (78), Rickie Fowler (79) and Tiger Woods (79).

What are their chances of making Open Championship 36-hole cut and playing the weekend? Well if the cut was made after just 18 holes, you needed to shoot three-over-par 74 or better to be inside the top 70 and ties. With 30 players posting even-par or better scores in the first round, the projected cutline from datagolf.com as of 10 a.m. Eastern on Friday was a 55.2 percent probability of five-over 147 being the number and a 43.9 percent probability it rises to six-over 148. 

As a point of reference, here’s what the Open Championship 36-hole cut line has been for the last 10 Opens:

2023: 145 (+3), Royal Liverpool 2022: 144 (E), St. Andrews 2021: 141 (+1), Royal St. George’s 2019: 143 (+1), Royal Portrush 2018: 145 (+3), Carnoustie 2017: 145 (+5), Royal Birkdale 2016: 146 (+4), Royal Troon 2015: 144 (E), St. Andrews 2014: 146 (+2), Royal Liverpool 2013: 150 (+8), Muirfield

And here is the cut for the last three Opens at Royal Troon:

2016: 146 (+4) 2004: 145 (+3) 1997: 147 (+5)

Is it the British Open or the Open Championship? The name of the final men’s major of the golf season is a subject of continued discussion. The event’s official name, as explained in this op-ed by former R&A chairman Ian Pattinson, is the Open Championship. But since many United States golf fans continue to refer to it as the British Open, and search news around the event accordingly, Golf Digest continues to utilize both names in its coverage.
