Ko Jin-young

Having become a professional in 2013 at age 18, Ko won 10 times on the LPGA of Korea Tour over the period 2014 to 2017, winning the Nefs Masterpiece in August 2014 as her first professional victory. In 2015, she was second at the Ricoh Women's British Open.[5] Ko won the 2017 LPGA KEB Hana Bank Championship,[6] after which she announced her plans to join the LPGA Tour in 2018.[7]

Ko played in 25 LPGA Tour events in 2018, missing only one cut and finishing in the top 10 of 13 tournaments.[8] In February, she won the ISPS Handa Women's Australian Open.[9] For the 2018 season, the LPGA named Ko the Louise Suggs Rolex Rookie of the Year.[1]

On 24 March 2019, Ko won the Bank of Hope Founders Cup on the LPGA Tour, and on 7 April 2019, she won her first LPGA major championship – the ANA Inspiration.[10] The victory elevated Ko to number one in the Women's World Golf Rankings.[11]

On 28 July 2019, Ko clinched her second major title of the season, firing a final round 4-under 67 in the rain to win the Evian Championship by two shots with a 15-under total of 269.[12]

On 25 August 2019, Ko won the Canadian Women's Open in Aurora, Ontario. She shot a tournament record −26 (262) and won by 5 strokes. She did not make a bogey for the entire 72 hole tournament.[13] Ko went bogey-free for a tour-record 114 holes, ending her streak at the Cambia Portland Classic.[14]

Having won the season's money title and Vare Trophy for lowest scoring average, Ko was named the LPGA Rolex Player of the Year for 2019.[3]

On 20 December 2020, Ko won the season-ending CME Group Tour Championship in Naples, Florida and the LPGA Tour's money title with only four starts.[15]

Between July and October 2021 in the United States, Ko won the Volunteers of America Classic in The Colony, Texas, the Portland Classic in West Linn, Oregon, and the Cognizant Founders Cup in West Caldwell, New Jersey.[16][17] By shooting 66 in her final round at the Founders Cup, she tied Annika Sörenstam's 16-year-old record of 14 consecutive rounds in the 60s.[16][17] Ko's streak began in the final round of the Evian Championship in July, enabling two wins, a second-place finish, and a tie for sixth in the four tournaments of the streak.[17]

Later in October 2021, Ko won the BMW Ladies Championship in South Korea for her fourth win of the year, 11th overall on the LPGA Tour, and the 200th victory on the LPGA by a South Korean.[18] Ko is the fifth South Korean with at least 10 career LPGA victories.[16][17] The victory at the BMW Ladies Championship re-established Ko as the world number one in the official women's golf ranking as of October 25,[19] but the 8 November ranking dropped her to #2, a fraction of an average point per event (9.028 to 9.032) behind Nelly Korda, because the calculations are over a two-year rolling average.[20][21]

In November 2021, Ko successfully defended her title at the CME Group Tour Championship in Naples, Florida. She also won the Race to the CME Globe, Player of the Year, and topped the money list.[22]

In March 2022, Ko won the HSBC Women's World Championship in Singapore. The was her 13th career LPGA win and sixth win in her last 10 starts since June 2021.[23]
