Australia's top two amateur golfers head up the leaderboard going into the final day of the Bowra and O'Dea WA Strokeplay Championships at Lake Karrin-yup Country Club today.
World No.1 Minjee Lee held a three-stroke lead going into yesterday's third round but world No.5 Su-Hyun Oh was able to narrow the gap to just one stroke ahead of what should be a thrilling final day's play at the prestigious course.
Royal Fremantle's Lee was unable to replicate the blistering pace of her opening two rounds yesterday, shooting a one-under-par 73.
Lee went on a birdie blitz on Monday but could manage just five in her third round, along with four bogeys.
Victorian Oh produced a consistent 71, which featured four birdies, to close in on her long-time rival.
Reigning champion Hannah Green is also within striking distance. The Mt Lawley teenager is two shots off Lee at 12-under after shooting a solid 71 in her third round.
WA Amateur winner Hayley Bettencourt is a further two shots back, with the Mandurah golfer seemingly the only other woman capable of claiming the title this afternoon.
Bettencourt beat Green in the final of the State Amateur recently and is hoping to lift her world ranking from 123.
Lee and Oh will tee off together this afternoon.
