Hull had just played an exquisite chip shot to 10 feet from a tough position left of the green, and as she went up to mark her golf ball play was briefly halted as several protesters strode onto the green with smoke flares and plumes of red and yellow dust.
While it was initially thought the protesters were from Just Stop Oil like we have seen at multiple sporting events in the country this season, it was in fact Money Rebellion, an arm of protest group Extinction Rebellion, who were protesting at the tournament sponsors.

Hull, 27, went on to miss her par save but she would hole a brilliant putt for par from 30 feet on 18 to finish 8-under par and secure her second runner-up finish in a major this season following her tie for second at the US Women's Open at Pebble Beach.

After the round, Hull gave her verdict on the protesters to Telegraph Sport:
Lilia Vu, who was playing alongside Hull in the final group in the final round, went on to win emphatically by six strokes - just as her American compatriot Brian Harman did at The Open Championship at Royal Liverpool last month.
Vu, 24, now moves to World No.1 for the first time in her career.
She also becomes the first American to win two major championships in a single season since Juli Inkster in 1999.
Vu won the Chervon Championship earlier in the season, and she has now won three times on the LPGA Tour in 2023.
