Laura Diaz digs deep late in her round to maintain the lead in the LPGA Marathon Classic in Ohio. Laura Diaz / Getty Images Laura birdied three of her final four holes to emerge from a three-way tie for the lead with a three-shot lead after the second round at the Marathon Classic. Her second round -2 under par 69 was good enough to separate her from the clutches of Lydia Ko and Lee Ann Pace. Laura posted a halfway total of -11 under par. She reported that having camera's on her was not a good thing; "For me, it was just a challenge because I haven’t been in this position in a very long time. For sure haven’t had cameras on me in a long time. So I was anxious for them to go away I think in a funny kind of way.” “A lot of the Golf Channel cameras were out and I was waving. They get in my face and I don’t really know what to do. I say, ‘Hi, kiddos, I love you.’ That kind of stuff.” Lydia carded a second consecutive round of -4 under par 67, to get to -8 under par for the tournament, and the 17 year-old was very happy to be playing solid golf; " You know what, I had two solid rounds. I thought I played pretty solid today and yesterday. Hopefully I can continue that through the weekend.” " I try and be calm, you know, that's what you have to do. Just I guess being overly happy or overly angry, that's not going to help me. That's what I think, so I try and stay calm." Lee Ann recorded a -3 under par 68 second round, and she also was very happy with her position going into the week-end; “I felt like I played really well, yeah, I’m very happy about the position. I would like to be in contention on the weekend. That’s when the fun starts, right? So hopefully I can keep hitting the ball like I am and make a couple of putts on the weekend, and you never know.” " It makes a big difference finishing birdie birdie, makes you feel a lot better going into tomorrow. I think back nine is definitely a little bit easier, more scorable, so very happy about this finish.” Worryingly Michelle Wie has now missed her second-consecutive cut after missing the weekend at the Women’s British Open last week, and now here, lets hope this is just a temporary set-back.
