Jenny is a past winner of the European Junior title, and other milestones are slowly being ticked off, including reaching the world top ten (in March 2005) and playing in England?s women?s team.
Talented and athletic, Jenny is clearly beginning to make her mark in the upper reaches of the world rankings. An indication of her development would be the win she scored over higher ranked Natalie Grainger in the first round of the Tournament of Champions in February 2005.
She also ended 2005 on a high beating Vicky Botwright to win the Prince Canary Islands Open.
There were mixed results in 2006 for the Harrogate, England based player, but she is such a good athlete with strong skills to match that it was only a matter of time before she was back on form.
However, if nothing else she could point to being part of the England side which triumphed at the World Teams in Canada in September 2006. And since then she showed that her confidence & game were blossoming as she won her national title for the first time in 2007 & was a semi finalist in the Seoul Open in Korea during April.
Her improved confidence was clear in her play as the year progressed.
Reaching the final of the Carol Weymuller US Open in November 2007 and also taking runner up slot in the Hurghada International in April 2008 did reinforce the conclusion that her top ten status was being consolidated; and this became more obvious when the British Open draw opened up and she reached her first British Open final in May 2008, only to be stopped by Nicol David.
This helped propel her up to a career best equalling six in the rankings, but this was bettered when she reached number five spot for the first time in August 2008 after quarter final placings in the CIMB Malaysian Open and Singapore Masters.
While momentum was maintained with a semi final finish at the World Open in October 2008, it was also an opportunity missed too. She had upset Natalie Grinham in the quarters only to beaten herself by surprise package Vicky Botwright in the last four. But the year did end on a high when she won the Sharm El Sheikh Open, beating Rachael Grinham in the final.
During 2009 she managed a Grinham double in May, beating Natalie in Cayman Islands and Rachael in Texas, but her first final came in Seoul where she again beat Rachael in the semis before being stopped by Nicol David.
In September Rachael got her revenge in the semi finals of the British Open and David beat her again in a very competitive World Open quarter final. Perhaps the toughness of this match was a signal for before the end of the year Duncalf had stunningly beaten David in the semi finals of the Qatar Classic and Carol Weymuller Open before going on to take both titles with final wins over Rachael Grinham and Alison Waters respectively. The winning bust had also taken in the Soho Square Open in Egypt, and saw her rising to number two in the WISPA rankings for the first time in December 2009.
While 2010 started well enough with her reaching the finals of the Chennai Open and Cayman Open, Nicol David reversed the defeats so she had to settle for runner-up slot in both events.
