That will change on Sunday.
World No. 1 Park shot a 3-under 69 Saturday to finish with a four-shot lead at the Fubon LPGA Taiwan Championship over No. 2 Lewis and No. 6 Shanshan Feng. The trio will be grouped together for the final round.
Lewis started the day nine shots behind Park, but she birdied four of the final five holes to fire an 8-under 64 in blustery conditions at the Miramar Golf and Country Club.
"I knew I needed some help with the weather to get a little bit closer," Lewis told reporters after her round.
Lewis loves playing in the wind, and she'll likely get her wish for the final round as gusty weather is expected again.
Lewis and Feng will need all the help they can get if they want to catch Park. She took back the No. 1 ranking from Lewis this week and shows no signs of giving it back.
Park made two sloppy bogeys on Nos. 8 and 9, but bounced back with a birdie on No. 9 and a chip-in eagle on the par-5 12th. She hasn't won since the Wegmans LPGA in August, but the recently-married Park hasn't finished outside the top 10 in her last four events.
Feng has also been playing well this year and won in Malaysia in early October. She just missed an eagle putt on 18 Saturday to remain in a tie for second with Lewis.
The trio have separated themselves from the field as Lewis and Feng are four clear of Azahara Munoz.
Park also has a chance for another important record on Sunday. She needs to shoot a 7-under 65 in the final round to break Annika Sorenstam's all-time scoring record of 27 under par set at the 2001 Standard Register Ping.
But with Lewis and Feng playing right beside her, Park will have enough to worry about in the final round.
