Doey Choi came into the Riversdale Cup with high hopes. The Sydneysider has delivered early with a brilliant, opening 68 to lead the Riversdale Cup in Melbourne.

Meanwhile on the men's side, Perth's Josh Greer and New South Welshman Christopher Fan have made the early running in one of the premier amateur tournaments in the world.

The tournament finally began on Friday morning after Thursday's play was washed out.

Choi, 20, had a rollercoaster round with eight birdies and three bogeys in her five-under total.

The Golf NSW prodigy is one of the highest-ranked players in the field and stands out as a likely winner, especially with Golf NSW teammate Grace Kim having started slowly with a 76.

She leads Metropolitan Golf Club's Jeneath Wong by a shot through round one.

Greer, coached by renowned Perth instructor Ritchie Smith an an International team representative at the Junior Presidents Cup, shot an opening 67. He was joined at the top by Avondale Golf Club's Fan at five-under par.

Neither will have much time to rest on their laurels.

In the pack immediately behind are two of Australia's best amateurs, Sydney's Nathan Barbieri and Victorian Andre Lautee, a shot back after opening with 68s.
