Kathryn Norris got back to breaking course records as she opened up a five shot lead over the girls field with a round to play at the Drummond Golf 54 Hole Classic in the south west.
The 16-year-old carded a 70 to break the previous ladies course record at Collie Golf Club, set by Helen Beatty in 1997, by two strokes.
Earlier this year Norris claimed the ladies record at Kwinana Golf Club, when she beat the boys to win the club’s Junior Open with a round of 69.
Norris had to work, however, just to score the lowest round of the day in the girls’ field after she birdied the last to edge ahead of state squad team-mate Kirsten Rudgeley, who fired a 71 to be in second place overall.
Adam Brady leads the boys’ field by three strokes after the 14-year-old Vines member also carded a 70.
Brady showed maturity beyond his years during a solid, no frills round that leaves him clear of Jose De Sousa (Gosnells), Connor Fewkes (Goldfields) and Cooper Geddes (Mandurah) who are in a three-way tie for second place ahead of the final round at Bunbury Golf Club on Friday.
Brady, a scratch marker, used positional golf to navigate his way around the 6,004m par-72 layout that features tight dogleg fairways and small undulating greens.
Adam putted well holing four three-metre plus putts for birdie together with some precision iron play to notch up five birdies in total against three bogeys.
Starting on the 10th he quickly got his round going with a birdie at the short par-four 12th but overshot the green with his approach at 15 and could not get up and down.
Finishing the back nine with a birdie at 18 he turned in one-under 35 and that seemed to jump start him as he quickly moved to four-under for the day with birdies at the first, third and fifth.
With solid regulation pars in between those birdies he found himself at four-under for the day.
Unfortunately, he overshot the sixth green with his approach and short-sided himself at the par-three seventh, dropping shots at both holes but finished with strong pars to sign for a two-under 70.
Norris had taken control of the tournament with a 76 at Capel on the opening day of the three-course event, which pushed her four shots clear of the chasing pack.
And after the girls made the short trip across to Collie today they could not have realised that two of them would become the first two females to break par at the course.
Norris began on the back-nine and bookended her first nine with birdies on the dogleg left par-five 10th, and short 330m 18th, around her only dropped shot at the testing short par-three 14th.
Birdie at the reachable par-five third was followed with another dropped shot at a par-three fourth before a string of solid pars culminated with a birdie three at the ninth to edge ahead of Rudgeley.
