Lydia Ko has safely secured a place in the second half of the richest tournament in women's golf after posting a solid round on day two of the US Open.
Coming off a disappointing opening round in which she struggled to a one-over 72, Ko was far more steady on Saturday with just a single blemish on a scorecard stacked with 14 pars.
A bogey on the fourth hole was balanced by three birdies - two in her final four holes - to leave the world No 3 in a tie for 21st at one-under par.
However, she has plenty of work to do over her final two rounds if she wants to compete for the $2.77m first-place prize.
Ko sits eight shots behind leaders Minjee Lee of Australia and Mina Harigae of the United States. Lee shot a five-under 66, and Harigae had a 69.
