Another standout grouping on Thursday morning will see world number one Dustin Johnson go out alongside Justin Rose and Will Zalatoris at 10:20am BST, 55 minutes after Jordan Spieth and Bryson DeChambeau get their campaigns under way in the company of South Africa’s Branden Grace. At the last two Opens, Grace played with the eventual Champion Golfer in rounds one and two (Francesco Molinari in 2018 and Lowry in 2019).
