Mariajo Uribe / AFP Colombian Mariajo Uribe leads the ISPS Handa Women's Australian Open golf championship at Royal Canberra after the second round. Mariajo leads by one shot after her composed second round of -6 under par 67 on the par 73 lay-out, and a tournament total of -15 under par. Overnight leader Lydia Ko is tied in second place with South Korea's Jiyai Shin, both at -14 under par. Lydia had five birdies in her round but bogeyed the par four 14th. She said the bogey was the result of a big bounce; "I just thought 6-iron would be the club and I hit it well, but it just took a big bounce and it went straight over the green. Four-under is a pretty good score out there. It's not an easy golf course, so I'm pretty sure it is a good score for me." Mariajo thinks she not hitting the ball that well, but her putting is good; "It's funny because the tournaments I've played better are the ones where I'm not hitting the ball that well. I come in with lower expectations. I'm not hitting the ball all that well, but I'm putting great. I figured Lydia was probably making a birdie too, because I saw her card yesterday and she makes a lot of birdies."
