Greaves is officially 120th in the PDC world rankings, which are based on prize money, and her ranking is likely to rise when she joins the main tour.
“In the ladies’ series, winning every time, that feeling becomes repetitive. Once you step onto the main tour and you’re losing a lot more it can knock your confidence,” added Humphries.
“But she’ll gain experience from it and playing against the best players week in, week out will make her a better player.
“If she’s at this standard now, give her two or three years and I do think she’ll be a top-32 player, maybe even top-16 or close to it. She’s got a great throw, good temperament, she’s good under pressure as well.”
As for this World Championship, Greaves would face world number 42 Callan Rydz in round two should she overcome Gurney, with 11th seed Josh Rock a potential third-round opponent.
“Fallon Sherrock got through a couple of rounds, but Beau Greaves could go further,” says Matt Edgar, who made three PDC World Championship appearances.
“She could go deep, she’s got the levels, I wouldn’t be surprised in a few years if we are talking about Beau Greaves being one of the favourites coming into this event once she’s gained a little more experience.
“She’s shown she can compete with the very best in the world.”
