Groupings and tee times for the third round of The 152nd Open at Royal Troon, where Shane Lowry heads into Saturday with a two-shot lead over the field.

Lowry added a second round of 69 to his opening 66 for a halfway total of seven under par and two-shot lead over English duo Justin Rose and Dan Brown, who both came through Final Qualifying earlier this month.

South Africa’s Darren Fichardt will hit the first shot of the day at 8.55am, with defending champion Brian Harman getting his third round underway just before lunchtime.

Lowry and Brown tee off in the final pairing at 3.45pm after world no.1 Scottie Scheffler, Rose and the rest of the chasing pack start their rounds.
