(CNN) -- Teenage sensation Lydia Ko followed up her record-breaking round of 10-under-par on day one of the Women's Australian Open with a score of 69, but it wasn't enough to retain the overall lead. Colombian Mariajo Uribe, whose round of nine-under on Thursday was overshadowed by her 15-year-old rival, again kept a bogey off her card as a 67 took her one shot clear on 15-under. Korean World No. 7 Jiyai Shin is hot on the heels of Uribe, her round of six-under drawing her level with Ko on 14-under as the trio gear up for a battle in Canberra over the weekend.
