Lydia Ko is golf’s youngest World No.1 at the age of 17

Lydia Ko became the youngest World No.1 in golf history by reaching the summit of the women’s rankings aged just 17.

The South Korean-born New Zealander secured the ranking by finished tied for second at the LPGA Coates Championship in Florida.

The victory eclipses even that of Tiger Woods, who at 21 years of age became the men’s World No.1 in 1997.

"It's amazing," Ko is quoted as saying on BBC Sport. "It's a huge honour to be in that ranking. All I was focused on was trying to play my best."

South Korea’s Jiyai Shin had been the youngest player to top the women’s rankings, achieving the status aged 22 in 2010.

Ko may have surrendered a four-stroke overnight lead in the opening LPGA event of the season, which was eventually won by South Korean Na-Yeon Choi, but it wasn’t enough stop her ascent to the top of the rankings.

Ko accumulated enough raking points to move past South Korea’s Inbee Park, who had been steadily holding her position as the top female golfer.

Of course reaching the World Rankings pinnacle isn’t the only record smashed by Ko in recent times. She became the youngest winner of an LPGA Tour event with victory in the Canadian Women’s Open in August 2012 at the age of 15.

Following this she turned professional in October 2013 and has surged ahead to claim five wins on the LPGA Tour and a single success on the European Tour.

"I'm just going to just focus on my golf, not think about the rankings," she said. "The rankings always come after the results."
