In 2009, Hoenselaar finally won the Women's World Championship, beating Gulliver in the final to record her first World Championship title, and a winner's cheque of £6,000. This earned her a spot at the 2009 Grand Slam of Darts, and was drawn in Group D with Raymond van Barneveld, John Part and Kevin Painter. Hoenselaar won four legs over her three matches, as she bowed out in the group stages.
