New Zealand golfer Lydia Ko says she's pleased with her opening round peformance as she bids for a three-peat titles at the LPGA's Swinging Skirts Classic in San Francisco.
Ko carded a four under par 68 to be tied for fifth, five shots behind the breakaway leader South Korean So Yeon Ryu, who shot a nine under par 63.
The world No.1 recorded six birdies and two bogies.
Ko, who turns 19 on Sunday, was happy with her round following a less than auspicious start.
"The big key around this course is to hit a lot of fairways and there were some holes where I wasn't there but I made quite a few good up and downs I'm really happy with that and I made a few birdies along the way so that really helped kick start my round after starting with a bogey on my second hole."
Ko is the two-time defending champion in San Francisco.
