Ko will be bidding for her first victory at a major championship at this week's U.S. Women's Open, having struggled at the year's opening two majors.
The 18-year-old began the year with six consecutive top-ten finishes, a run which included victory at the Australian Open. After struggling to a tie for 41st spot at the ANA Inspiration, Ko bounced back to win the Swinging Skirts LPGA Classic, but since then has not had the best of times.
A missed cut at the Women's PGA Championship last month extended Ko's run of woe at the majors, one she is hoping to turnaround at the Lancaster Country Club this week. The New Zealander enters the event on the back of a tie sixth-placed finish last time out at the NW Arkansas Championship, a result which has left her feeling buoyed.
"Getting that top-10 finish in Arkansas is definitely a good confidence booster for this week," she explained.
"Every tournament is different, week-by-week. You can shoot 20-under par one week and then shoot even par the next.
"I just kind of have to forget about it, just be excited again."
