Lydia Ko

 ( Www.lydiako.co.nz Official Website ) 

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.

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.

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.

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.

Ko ended the 2017 season with a scoring average of 68.86 which ranked her No. 9 and a total season earnings of $1,177,450 which put her at No. 13 on the season's money list. This was the fourth consecutive season in which she won at least $1,000,000.

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.

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.

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.

On 28 November, she returned to the Number 1 ranking for the first time since 2017, but has since dropped to number 3 as of July 31, 2023.

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. The gold medal win qualified her to become the 35th and youngest inductee into the LPGA Hall of Fame.

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.
