Hyo Joo Kim leads Lydia Ko after flawless first round at Open

She tapped in for eagle.

She was one of the early starters and had the alarm set for 3:30am but it worked out for her as she shot her best ever round at major tournament. She admitted she pressed the snooze button a few times before getting up to eat breakfast cooked by her mum.

She says her putting was good today and managed to sink a couple of long ones, while any mistakes she made landed in good places.

Not that the incredibly mature teenager bothers too much about breaking records.

“He flew above us at the flawless time and I was like, man, that’s a really nice helicopter”.

The American won the 2007 Kraft Nabisco Championship when she was two months short of her 19th birthday.

“The last couple weeks, I couldn’t swing very well”. “I would definitely think about doing it again next year”.

The two-time Ladies European Tour victor continued: “This is the first course I had never played as an amateur, as well”.

She said: “It was brilliant”. I was so intimidated by the course and I kept saying to my friend, if I shoot under 80 today, I’m going to be thrilled.

“But it is early days. I stayed patient. My game is in good shape, so excited to go out again tomorrow”.

Kerr hit a 5-iron to 20 feet and holed the putt for an eagle three at the 462-yard third.

She was also pleased with the remainder of her round, particularly her recovery play. “Turnberry’s great and the weather was spectacular”, said the 37-year-old.

She took part in the Scottish Open at Dundonald Links further up the coast last week.

Kim took advantage of the favourable weather to post a seven under par 65 and raise her hopes of adding a second major to her victory in the Evian Championship in France last September.

England’s Florentyna Parker shot a four-under-par 68, one shot ahead of world number one Inbee Park. “But three under is not bad for the first day”.

Oddest round of the day belonged to Paula Creamer. She was out in 40 and home in 31 for a 71.

The highlight of Ko’s round was four straight birdies from the second to the fifth hole.

“I was two different players”, said the 2010 US Women s Open champion.
