Leona Maguire slumps to a 76 as Haeran Ryu leads the way in Canada

Leona Maguire struggled to a four-over-par 76 at the the CPKC Women's Open, where South Korean Haeran Ryu will take a one-shot lead into the final round.

Maguire began the day nine shots off the lead at Earl Grey Golf Club in Calgary after just making the cut, but Saturday was a day of toil for the Cavan native.

FULL LEADERBOARD

Four bogeys in the opening five holes was a sluggish start, but Maguire showed grit to then reel off three successive birdies, beginning at the sixth.

The back nine started steady before dropping a shot at 14 and concluding her round with double-bogey at the last for 76 to drop to seven over par.

That is 20 shots adrift of Ryu, who collected seven birdies and one eagle against just one bogey to sit at 13 under.

She swapped spots with second-round leader Lauren Coughlin, who carded a six-under 66 to drop to second.

It couldn't have been a much better start for Ryu, as the 23-year-old opened her round with four birdies before making par at the fifth. She then got right back on a roll with another birdie at the par-four sixth.

After settling for her lone bogey of the day at the par-four 12th, Ryu went birdie-eagle, then closed her round with four pars.
