Ha Na Jang of South Korea is back at the No. 5 spot in the Women's World Golf Rankings released Tuesday after her 12th professional victory at last week's Women's Australian Open.
Jang, 24, finished with a three-stroke lead over Denmark's Nanna Koerstz Madsen at 10-under 282 in Seaton, South Australia. She was previously ranked No. 5 after winning the 2016 HSBC Women's Champions.
This marks Jang's third week ranked in the top five of her career. Since the start of 2016, Jang has four wins -- including two in her last six events on the LPGA Tour. She has the Tour's highest winning percentage (18.2 percent) during that span.
Only Thailand's Ariya Jutanugarn (five) has more wins since the start of 2016.
New Zealand's Lydia Ko remains No. 1 in the world for the 70th consecutive week. Ko, who finished tied for 46th at the Women's Australian Open, has spent 184 weeks ranked in the top 10.
Jutangran remains second while China's Shanshan Feng moved up one spot to third. South Korea's InGee Chun dropped one spot to fourth.
Lexi Thompson is the highest-ranked American, dropping one spot to No. 6. South Korea's So Yeon Ryu jumped two spots to No. 7 while South Korea's Sei Young Kim, Canada's Brooke Henderson and South Korea's Sung Hyun Park round out the top 10.
