'I feel pretty great in my life. No complaints, especially this week,' said Pak. 'My swing feels great. I enjoy the game but it's a good thing I won the tournament.'
Pak captured her third title of 2002 and her 16th since joining the LPGA Tour in 1998. Her name will now go down in the Betsy King Classic record books.
Pak's 63 matched the course record set by Tina Barrett in the first round of the 2000 edition, and her tournament total of 267 was three better than the record Annika Sorenstam put up in winning the 1996 title.
The 24-year-old South Korean also posted the lowest 72-hole total of 2002, once again trumping Sorenstam. The Swede held the distinction for her 19-under-par 269 in the Evian Masters.
Angela Stanford carded a 66 in the final round to finish alone in second place at 18-under par. Karrie Webb shot a 3-under 69 to take third place at minus-16.
Pak began the round three shots behind Michelle Ellis and despite a birdie at the opening hole, things did not look promising. She missed the green at the second and failed to save par from six feet. Pak lost another stroke a hole later when she could not recover from another missed green, but those would be the only miscues she would face the rest of the way.
Pak eagled the par-5 fifth to reclaim the lost strokes and drained a 20-foot birdie try at the sixth. She holed a 15-foot birdie putt at the eighth to polish off a 3-under 32 on the front side.
On the back nine, Pak climbed the leaderboard and eventually passed the field. She ran home a six-foot birdie at 12 and made it two in a row with a a six-footer at the 13th.
Stanford had taken the lead on the back nine but Pak was too dominant in the end. Pak converted a 20-foot birdie at the 15th and took advantage of another par-5, the 16th, to birdie the hole and reach 19-under par.
Pak played a 9-iron to six feet at the 17th and wrapped up the title with a two-putt birdie at the last after nearly holing her second shot for double-eagle.
'I saw ahead of me Angela making birdies and I heard the crowd and it was pretty exciting,' said Pak, who earned $180,000 for the victory and moved to second on the 2002 LPGA money list. 'I said go out there and do my best.'
Stanford collected seven birdies and one bogey Sunday on her way to her highest finish as a professional.
Catriona Matthew carded a 65 and finished fourth at 15-under par. Wendy Doolan took a solo fifth at minus 14.
Ellis struggled to a 2-over-par 74 and shared sixth with Joanne Morley and Danielle Ammaccapane. The group came in at 13-under-par 275.
