Still three months short of her 17th birthday when she won last year's European Amateur Championship on July 23 and with it became exempt for the 2022 AIG Women’s Open. Tied for the lead with England’s Charlotte Heath after 54 and 72 holes, both finishing 19 under par, they could not be separated in the three-hole aggregate play-off, but when they went into sudden death De Bock’s par made her the first Belgian winner of the title since Florence Descampe in 1988.
De Bock held her nerve in an even longer play-off to reach this year's Championship. She eventually progressed from Final Qualifying at Hankley Common after parring the seventh hole of a play-off that started with 13 players, was halted due to darkness on Monday, and was then completed the following morning.
