Sorenstam, seeded No. 1 based on her position atop the 2001 LPGA money list, was 5-up with five holes remaining but had to hold off a late surge by third-seeded Lorie Kane. Sorenstam won the 16th hole to post a 4-and-2 triumph over her Canadian counterpart.
Pak, chasing Sorenstam for the season money title and Player of the Year honors, earned her spot in the championship tilt with a 6-and-4 drubbing of Japan LPGA Tour player Yu-Chen Huang.
The winner will collect $144,000 from the $960,000 purse. The runner-up takes home $90,000.
This event, the first match-play tournament on the LPGA schedule since 1992, is being contested at Sohsei Country Club in Japan. It replaced the World Ladies Challenge, an unofficial team event that pitted the LPGA against the JLPGA from 1979-2000. The LPGA dominated the series with a 19-3 record.
