Lydia Ko

Ko was born on 24 April 1997 in Seoul, South Korea, and emigrated with her family to New Zealand when she was four, gaining New Zealand citizenship at age 12. She began playing golf as a five-year-old when her mother took her into a pro shop at the Pupuke Golf Club on Auckland's North Shore owned by professional Guy Wilson, who coached her until 22 December 2013. She was a seven-year-old in March 2005 when she first came to the attention of the media, for competing in the New Zealand national amateur championships. She was educated at Mairangi Bay Primary and Pinehurst School in Albany, New Zealand, and when she joined the professional golf tour she took correspondence classes with Pinehurst. Starting in 2015 Ko said she would study psychology extramurally with Korea University, Seoul. The Yonhap news agency reported her as saying "I'll have to listen to what the university says to decide how I will do my studies. I'll have to make sure I submit the required papers and projects as the majority of my classes will be done online." ==2012 Women's NSW Open==

On 29 January 2012, Ko became the youngest person ever to win a professional golf tour event by winning the Bing Lee/Samsung Women's NSW Open on the ALPG Tour. She was 14 at the time, and had placed second in the event the year before. The previous youngest person ever to win a professional golf tour event was Japan's Ryo Ishikawa at age 15 years and 8 months. Her record as the youngest winner of a professional event was broken later in 2012 by 14-year-old Canadian Brooke Henderson, who won the second event on that year's Canadian Women's Tour on 13 June. ==2012 and 2013 CN Canadian Women's Open==

On 26 August 2012, at the age of 15 years and four months, Ko became the youngest-ever winner of an LPGA Tour event, winning with a score of 275 (−13) at the CN Canadian Women's Open. She surpassed the record set by Lexi Thompson at 16 years and seven months in September 2011. Her win also made her only the fifth amateur to have won an LPGA Tour event, and the first in over 43 years. The 2012 CN Canadian Women's Open was a 72-hole event with a purse of $2 million; the winner's share of $300,000 went to runner-up Inbee Park who was three strokes back. Ko successfully defended her win at the 2013 CN Canadian Open, shooting 265 (−15) for a five-stroke victory over Karine Icher at the Royal Mayfair Club in Edmonton. The $300,000 winner's share went to Icher. ==Professional career==

After finishing runner-up to Suzann Pettersen in The Evian Championship in France, Ko announced that she would turn pro in 2014. However, on 23 October 2013, she stated in a YouTube video featuring New Zealand rugby player Israel Dagg that she was turning professional immediately and would play her first professional tournament in Florida in mid-November. She had been the top-ranked woman amateur golfer in the world for 130 weeks when she announced she was turning professional on 23 October 2013. She finished tied for 21st in her pro debut at the 2013 CME Group Titleholders. In October 2013, the LPGA Tour granted Ko's request to join the LPGA, waiving the Tour's requirement of members being at least 18 years old. "It is not often that the LPGA welcomes a rookie who is already a back-to-back LPGA Tour champion," tour commissioner Mike Whan said when he granted Ko's request. In November 2013, Ko began working with swing coach David Leadbetter. 2014 Ko won three tournaments in 2014. On 27 April 2014, she earned her first LPGA Tour win as a professional and her first win on U.S. soil, by winning the Swinging Skirts LPGA Classic. She celebrated her 17th birthday during this tournament. In July, she won her second tournament of the year, the Marathon Classic. In November 2014, she won her third tournament of the season, the season ending CME Group Tour Championship. She won the LPGA Rookie of the Year. Ko commemorated the occasion with the inscription "IV-XXVII-XIV" (4-27-14 in Roman numerals), on her right wrist. 2015 Ko won five times in 2015. On 2 February 2015, she became the No. 1 ranked woman professional golfer after a runner-up finish at the Coates Golf Championship, overtaking Inbee Park. On 22 February 2015, Ko won her first event of the 2015 LPGA Tour season at the ISPS Handa Women's Australian Open. The win was her sixth on the LPGA Tour, and her ninth victory overall. The following week, Ko returned home and won her tenth professional championship at the ISPS Handa New Zealand Women's Open. The victory in this tournament was her second of the 2015 season, the win was also her third on the Ladies European Tour, and fourth with ALPG Tour. Highlighted in her victory at New Zealand was her LET low-round tying and course record 61 during the second round. At the first major of the 2015 season, the ANA Inspiration, Ko shot a 1-under-par 71 in the first round on 2 April, tying her with Annika Sörenstam for the all-time LPGA record for consecutive rounds under par, at 29. Three weeks later, Ko would win her second LPGA Tour event of the 2015 season, when she beat Morgan Pressel in a playoff to win the Swinging Skirts LPGA Classic. She would defeat Pressel with birdie on the second playoff hole. The victory was her seventh overall on tour, and her second win at the event in as many years. Her win was also her third win worldwide in 2015. The victory would be the second time she has defended a championship on tour. The playoff win was also her second on tour, bringing her playoff record to 2–0. Ko would go on to miss the cut at the 2015 KPMG Women's PGA Championship. The missed cut would be her first in her fourteen major championship appearances. She would find solid success in her next two major championships with a T12 finish at the 2015 U.S. Women's Open, and a T3 finish at the 2015 Ricoh Women's British Open. On 23 August 2015, Ko won her third Canadian Pacific Women's Open in a playoff against Stacy Lewis. She defeated Lewis, with par on the first hole of the playoff. The victory was the eighth for Ko on the LPGA Tour, and the third of the 2015 season, and fourth win worldwide for her in 2015. The playoff victory was also her third win in such circumstances, and would bring her career LPGA playoff record to 3–0. On 13 September 2015, Ko won the fifth and final major on the 2015 LPGA calendar, the 2015 Evian Championship. She dominated the final round with eight birdies, winning by six shots over second-place finisher Lexi Thompson. Her 63 was the lowest-ever closing round score in a women's major championship. It was Ko's fourth win on the LPGA Tour in 2015, ninth on the LPGA Tour overall and fourth on the Ladies European Tour. Ko's victory also made her the youngest major champion in the history of the LPGA Tour and the youngest major champion in golf since Young Tom Morris, when he won the 1868 Open Championship. On 26 October 2015, Ko became the youngest player to win 10 events on a major tour at age surpassing Horton Smith who set the PGA Tour mark of 21 years, 7 months in 1929, and Nancy Lopez who set the previous LPGA Tour record in 1979 at 22 years, 2 months, 5 days. On 22 November 2015, Ko won the LPGA Rolex Player of the Year Award by two points over Inbee Park, making her the youngest winner in the 49 years of the award. 2016 Ko won four times in 2016. Ko's 2016 started where she left off from 2015, winning the ISPS Handa New Zealand Women's Open for a third time in four years by two shots from Choi Hye-jin, Felicity Johnson, and Nanna Koerstz Madsen. Just 11 minutes before she was due to tee off for her final round, an earthquake struck, with Ko vowing to donate her prize money to charity to help those affected. On the LPGA Tour, Ko won the Kia Classic in March with a four-shot margin over Inbee Park, and the following week, on 3 April, she made it consecutive major titles with a one-shot victory at the ANA Inspiration. The win strengthened her position as No. 1 in the world as she became the youngest double major winner in the history of the game since Young Tom Morris at the 1869 Open Championship. Later, she added two more victories on the LPGA Tour at the Walmart NW Arkansas Championship and Marathon Classic. In August, she represented New Zealand at the 2016 Rio de Janeiro Summer Olympics, where she won the silver medal. Ko was runner-up for the Vare Trophy (lowest scoring average) for a second consecutive year; however, last year's difference of 0.026 was, literally, twice as much as this year's 0.013 which separated her from winner Chun In-gee. Following the 2016 season, Ko announced that she had signed an equipment sponsorship contract with Parson's Xtreme Golf (PXG), ending her use of Callaway equipment. Ko also announced in December that she had parted ways with both her caddie and swing coach David Leadbetter, who had been coaching Ko since November 2013. The season ending CME Group Tour Championship was Ko's 100th tournament on the LPGA Tour as a professional. After just 14 LPGA tournaments (22 worldwide tournaments), Ko broke into the Rolex Rankings top-10 at No. 7 by winning her second Tour title on 25 August 2013. She has remained in the Rolex Rankings top-10 for the last 231 consecutive weeks (or ), as of 22 January 2018. Then after her first 44 LPGA tournaments, Ko ascended to the world No. 1 ranking for the first time on 2 February 2015. She was the world No. 1 for 85 weeks until June 2017. 2018 Ko entered 26 tournaments, won once, at the LPGA Mediheal Championship, and finished in the top-10 ten times. For her services to golf, Ko was named a Member of the New Zealand Order of Merit in December. 2019 Ko entered 24 events and finished in the top-10 four times. 2020 Ko entered 13 tournaments and finished in the top-10 four times. 2021 Ko entered 20 LPGA events, winning once.

In August, Ko represented New Zealand at the covid-delayed Tokyo Summer Olympics, where she won a bronze medal. Ko won the 2021 Vare Trophy for the lowest scoring average on the LPGA Tour. She closed the trophy out in November by finishing second in a playoff at the Pelican Women's Championship and shooting a final round 64 to finish in the top 10 at the CME Group Tour Championship. Nelly Korda and Ko Jin-young both finished the year with lower scoring averages than Ko but neither completed the required 70 rounds over the season to be eligible for the trophy. 2022 Ko entered 22 tournaments and won three times. She secured her 17th LPGA win on 30 January at the Gainbridge LPGA at Boca Rio, beating Danielle Kang by one stroke, 274 (14 under par) to Kang's 275 in a back-and-forth lead in the fourth round. She claimed her 18th LPGA win on 23 October, at the BMW Ladies Championship in Wonju, located approximately east of her Seoul, South Korea birthplace. In November, Ko won the CME Group Tour Championship and the record $2 million first prize. With the win, Ko won the season's money title, Vare Trophy for lowest scoring average and the LPGA Player of the Year for 2022. 2023 Ko entered 24 tournaments and won once. In February, Ko won the Aramco Saudi Ladies International in Saudi Arabia for the second time. The purse for this Ladies European Tour event was larger than that of all non-major tournaments on the LPGA Tour and the Ladies European Tour, providing $750,000 as Ko's winning award. In December, Ko won the inaugural Grant Thornton Invitational mixed team tournament with playing partner Jason Day. 2024 Ko entered 21 LPGA and Olympic events, winning 4 times. In January, Ko secured her first LPGA Tour title since 2022 by winning the Hilton Grand Vacations Tournament of Champions. On 10 August 2024, she won the gold medal in women's golf at the Paris 2024 Summer Olympics, giving her a complete set of Olympic medals – silver, bronze and gold – the only golfer in the modern era to achieve all three medals at three different Olympic Games. Two weeks later, Ko claimed the AIG Women's Open at Old Course at St Andrews, her third major championship. In September, she won the Kroger Queen City Championship, the first time since 2016 that she won back-to-back LPGA Tour events. In December, she was named a Dame Companion of the New Zealand Order of Merit (DNZM) for her services to golf, one of New Zealand's highest civil honors. In New Zealand and the Commonwealth – where Dame is the female equivalent of a Knight, Ko became the youngest person ever at the age of 27 to be appointed a Dame. 2026 At the 2026 Ford Championship in March, Ko posted a first round score of 60, a career low single-round score. == Personal life ==
