The projected cut line at the Open Championship sat at +1 during the morning wave of Round 2 on Friday at Royal Birkdale, putting the field on a knife edge before the weekend spots were decided.
That mattered because only the top 70 golfers and ties after 36 holes would advance, and a live model from Data Golf gave the +1 line a 53.3% chance of holding, a 14.3% chance of moving to +2 and a 31.7% chance of dropping to even par.
Justin Rose was among the names hovering around trouble, and he had a particular reason to feel the pressure in England. He burst onto the professional golf scene as a 17-year-old amateur at Royal Birkdale in 1998, making the course part of his own story long before Friday’s cutoff drama.
He was not alone. Rory McIlroy, Jordan Spieth, Wyndham Clark and Brian Harman were all described as flirting the projected line after their opening 18 holes, a group that included a two-time defending Masters champion, a player whose last major win came at Royal Birkdale in 2017, a recent U.S. Open winner and the Open champion from three years ago.
That is what gives the number its weight: at this stage of the tournament, a single stroke can separate a player from the final two rounds. Dry conditions and minimal wind were forecast for England for the rest of the event, which can leave mistakes exposed and make the cut battle even more unforgiving.
The live picture still depended on the rest of Round 2, and that is where the uncertainty sat. Anyone at +1 or better was still on track, anyone below it was chasing, and the final verdict would come once Friday’s 36 holes were complete.
