Ko easily into second round at US amateur

Lydia Ko has easily progressed to the second round of the US Girl's Junior Amateur Championship in California.

Ko, who qualified as the No 2 seed for the event, beat American Mikayla Harmon by 7 and 6 to set up a second round match with Californian Hee Wook Choi who is seeded 31st.

A bogey on the first hole was the only blip for the world No 1 amatuer as she then reeled off eight wins in an 11 hole stretch.

"I don't think there were much negatives in my round today," said Ko.

"It's good to see my scores improving day by day."

The US Girls' Junior continues Thursday (local time) with the second and third rounds of match play.

The quarter-final and semi-final matches are on Friday, and the 36-hole championship final will be played Saturday.
