In 2019, Sherrock became the first female to win a match, and subsequently two consecutive matches, at the PDC World Championships, first by beating Ted Evetts 3–2 in the first round, and then Mensur Suljović 3–1 in the second round, before eventually losing 2–4 to Chris Dobey in the third round. The event saw her earn the nickname "Queen of the Palace" after the PDC World Championships' current venue, the Alexandra Palace.
