2025 event. After wins over
Stefan Bellmont, Rhys Griffin and
Mickey Mansell, she was drawn to play world number one
Luke Humphries in the fourth round. She led the match 7–5 but conceded the next five legs to lose 10–7. Humphries praised her in his post-match interview, stating, "She belongs in this environment. She really did test me there and if we were in a Premier League game she would have beaten me." Throughout the year, Greaves competed on all three of the
PDC's secondary tours: the
Women's Series,
Challenge Tour, and
Development Tour. In late February, following title wins on each tour, she occupied the top spots on the Women's Series, Challenge Tour and Development Tour Orders of Merit concurrently, becoming the first player in PDC history to do so.
