However, she is yet to win three more Majors to complete a career grand slam.This week, she is at Erin Hills Golf Course in Wisconsin to claim a US Women's Open title, a Major Championship that she is chasing with intent. Heading into the second Major of the season this week, Ko talked about her career grand slam chase."I think as long as I'm playing, it's always good to have a goal so that when I'm working on things, I'm always going forward and not trying to think, 'Oh, I did this, so who cares?' It's more to keep myself more motivated. Hopefully not, but even if I never win a U.S. Women's Open, I don't think I'm going to wake up from my sleep and go, 'I never won'," she was quoted as saying by the LPGA Tour.Although the Kiwi golfer mentioned that she will be elated if she can win the Major event this week, she won't tie that into her identity."I'm very proud of the things that have happened, and I would be over the moon if I, especially this week, come off with a trophy. But I don't think that's going to connect me more so to my identity later on," she added.Lydia Ko is one of the marquee names on the LPGA Tour. The 28-year-old is already a member of the LPGA Hall of Fame and has 23 LPGA Tour titles to her name.
