Second seed Sharon Wee made it through to the semi-finals of the Women's Berkshire Open in Williamstown, USA - but the Malaysian had to save two match balls before overcoming England's seventh seed Lauren Siddall in the WISPA World Tour squash event at Williams College.
In a quarter-final described by event spokesman Zafi Levy as 'the match of the night', 22-year-old Siddall, from Yorkshire, took the opening two games. But the defending champion swept back to draw level for the loss of only two points.
The dramatic decider went to nine-all before Wee finally prevailed 3-9, 4-9, 9-0, 9-2, 10-9.
Wee will face Latasha Khan, the third seed from the USA, for a place in her second successive final.
The other final will be an all-New Zealand affair between top seed Shelley Kitchen and fourth seed Louise Crome - both of whom enjoyed straight games quarter-final victories which have set up a repeat of last month's New Zealand Nationals final.
Semi-final line-up:
[1] Shelley Kitchen (NZL) v [4] Louise Crome (NZL)
[2] Sharon Wee (MAS) v [3] Latasha Khan (USA)
