Catriona Matthew is in a class of her own following her second round -7 under par 64 at the Manulife LPGA Classic at the Grey Silo Golf Course in Canada. Catriona followed her first round 63 with a second round score of 64, for a tournament total of -15 under par, three shots clear of the field. She said she had taken advantage of the chances that came her way; " It feels really good, I've holed a lot of putts but I've given myself a lot of chances. I wouldn't really say I've holed many super-long ones but just every time I've given myself a chance I'm kind of taking advantage of them." Angela Stanford is in second place at -12 under par, shooting a -4 under par 67, and said she was enjoying the soft conditions; " I think the firmness of the greens last year made it a little bit tougher, you had to kind of pay attention to where you were landing it. This week they're so soft you can kind of go pin hunting. Any time I'm feeling this way, I can't wait to try to make the putts. Course conditions determine a lot. This setup, like last year, was not easy, anywhere in the world if greens get soft, it makes it a lot more accessible. So I don't think the layout is what makes it easy. I think just the fact that they've had so much rain here and it's softer. But if it's firm and fast, then you've got to pay attention to where you land your ball and running through fairways. So I think it's just the greens being soft has been our gift this week." Anna Nordqvist of Sweden shot a second round of 64 and was one of many tied at -11 under par, including American Ryann O'Toole, Spain's Belen Mozo, South Korea's Chella Choi and Meena Lee. Inbee Park of South Korea, who is looking to win her fourth straight LPGA Tour event, shot a second round of -4 under par 67. Inbee is tied in eight place at -10 under par, five shots off the pace, and will need a good round tomorrow if she is to contend here.
