They're unfamiliar names to Australian golf fans but young South Koreans So-Yeon Ryu and Hee-Kyung Seo already have a history of fighting out golf tournaments - and big ones at that.
The `Seoul Sisters' could be at it again on Sunday afternoon at Royal Pines on the Gold Coast in the finale to the Australian Ladies Masters after both shot flawless rounds of six-under 66 in the opening round yesterday.
The pair, who battled over the closing stages of last year's US Open before Ryu triumphed, ended the day tied for second with Dutch professional Christel Boeljon to sit one shot behind compatriot Bo-Mee Lee (65).
Teenage American star Lexi Thompson, a two-time winner last year, England's Felicity Thomson and Australians Nikki Campbell and Stephanie Na did their best to gatecrash the Korean party, finishing on five-under 67.
Thompson, 16, played with 14-year-old New Zealander Lydia Ko, who bogeyed two of her last four holes to finish on two-under 70.
Destined for a huge career, Thompson was impressed by her younger playing partner who last weekend made golfing history as the youngest player - male or female - to win a professional golf tournament.
