Katherine Hull-Kirk is one of four players sitting atop of a jam packed leaderboard after the first-round of the LPGA KEB•HanaBank Championship.

The quartet of players, which includes Hull, South Korean Amy Yang, Swede Anna Nordqvist and KLPGA all carded 5-under 67’s to grab ahold of the lead.

The Queenslander has been a little frustrated with her results, as she has been hitting the ball really well but not holing enough putts.

“The last few years have been a little bit frustrating but at the same time, I`ve learned a lot and I think I`m a better player now than I was even when I won,” said Hull-Kirk. “I think my best golf is still ahead of me, so I`m excited for the future and hopefully a lot more wins.”

With her game better than ever, the Aussie wasted little time moving into the red numbers after reeling off three birdies in her first three holes. Momentum continued to swing Hull-Kirk’s way during the remaining opening 9-holes as she made the turn at 5-under needing only 11 putts.

“I had a hard time on the first nine holes I played,” said Hull-Kirk. “I think I had 11 putts through the first nine holes, so that was really what got my round going.”

Despite cooling off a bit on the back-nine, Hull-Kirk feels right at home this week in South Korea and on the immaculate Sky 72 Golf Club.

“This is definitely one of best golf courses we play all year,” said Hull-Kirk. “It`s always in perfect condition. The bunkers are great and I really love the greens here because they are so true and they roll probably on the faster scale for us.”

Swede Caroline Hedwall is outright fifth at four-under, while another seven players including Americans Michelle Wie and Brittany Lang and Norway’s Suzann Petterson just a shot further back. 32 players are under par after the first round.

Hull-Kirk is the only Australian playing this week in the limited field event.
