Jack McDonald

The grandson of Gordon Cosh, who played in the famous “Duel in the Sun” Open at Turnberry in 1977, Jack McDonald will play in the championship for the second time in three years.

This is not the first time McDonald has followed in his grandfather’s footsteps.

In 1965, Cosh won three of his four games as the Great Britain and Ireland Walker Cup side drew in Baltimore – the first time America had not won since the series began in 1922. McDonald played the same match at Royal Lytham and St Annes in 2015 as part of a side that beat a United States line-up, which included Bryson DeChambeau, by a record seven-point margin.

Jack is now returning to The Open after coming through Final Qualifying at Dundonald Links, just as he did in 2024. McDonald was the leading qualifier at the Ayrshire venue this time around, with a five-under aggregate for 36 holes.

He missed the cut by one shot in The 152nd Open and said: "After I played at Troon I just wanted to play The Open again. It was such a good event that I wanted to get back there."

As a 19-year-old amateur, he made the cut at the 2012 Scottish Open. McDonald is also a former winner on the EuroPro Tour.
