Sherrock had secured one of two spots for female players in the 96-person field. The other qualifier, Mikuru Suzuki of Japan, lost 3-2 to James Richardson on Sunday, the BBC reported.
Sherrock said the history-making feat was exciting.
"This is definitely one of the best moments I've had. I'm just so happy. I've just made history. I can't believe it. I've made a great achievement for women's darts," Sherrock, who was the BDO Women's World Championship runner-up in 2015, told the BBC.
