Experience is Lydia Ko's most valuable weapon as the Kiwi golfer fronts for tonight's start to the US Open.
The world No 1 has claimed multiple titles in four years as a professional and pinpoints that education as a boost for this year's third major on the CordeValle course in California.
Ko won the ANA Inspiration this year and was edged in a playoff with Brooke Henderson for the PGA Championship title last month. Ko's best finish in four US Open attempts has been 12th but she likes her chances this time.
Her game is in strong shape, the course suits her eye and she feels comfortable in the west coast conditions. Her time on tour had taught her about being patient especially in the majors.
"It is not thinking about low scores but being patient and consistent," she said. "You are never out of it, even if you are four or six shots behind you are still in a tournament like this."
