Aussie Kirk's perfect 10-under LPGA round

Australia’s Katherine Kirk has produced a stunning form reversal with a record-tying 10-under-par 62 to lead the LPGA Tour’s Thornberry Creek Classic.

Less than a week after shooting a career-worst 83 at the Women’s PGA Championship, Kirk notched her personal-best score as she bagged 10 birdies on Thursday.

“Golf is funny,” Kirk told reporters after taking a one-shot first-round lead from South Korea’s Sei Young Kim.

“When you’ve played it as long as I have professionally you realise some days will be good and some will be bad.”

The defending champion Kirk was on fire from the outset, opening with three successive birdies and bagging seven in her first nine after starting from the 10th hole at Thornberry Creek at Oneida in Wisconsin.

Her round was about as close to statistical perfection as it gets in golf as she hit 14 of 14 fairways, hit 17 of 18 greens and needed just 25 putts.

Canada’s Brittany Marchand and American Megan Khang are tied third at eight under after a day of red-hot scoring.
