Ariya Jutanugarn leads after the opening round of the Reignwood LPGA Classic, but admits there is still work ahead.
The Thai superstar leads by one stroke from Brooke Henderson following a superb eight under 65, one off the tournament record.
Despite ten birdies, Jutanugarn believes there is still work to do on the range.
"Today I think today my iron was not that good," said the Women's British Open champion after the round.
"Was okay. Just have to work on my iron a little bit today. Today I really like want to have fun and enjoy in the course and just like make sure I do like focus on like what's under my control. Not worry about the outcome, the result."
Meanwhile, Henderson closed with back-to-back birdies for her 66.
"I'm looking forward to being really in Asia for the first time," said the Canadian, who will spend some time travelling.
"I've visited a few other times, but this will really be the true taste of a bunch different countries and language and culture, so I am really looking forward to it."
