On the last day, Ryu leads on 11 under, one stroke behind American Korda, who is attempting to match the LPGA record of five wins in five starts.
Brooke Henderson of Canada is also tied for second place with 10 under.
After storms postponed play on Saturday, round three completed early on Sunday.
Play was paused in the first major of the year, with Thailand’s Atthaya Thitikul leading Korda and Henderson, who had recorded a spectacular eight under through her first 17 holes, by one shot at 11 under.
However, Thitikul is currently tied for third place at eight under with South Korea’s team.
