The world No. 1 wished she had played a full 18-hole practice round ahead of the year's first major championship, but said “it’s on me.”

Nelly Korda’s defense of her Chevron Championship title got off to such a rough start that the world’s top-ranked golfer is in serious danger of missing the cut in the LPGA’s first major of the year.

Korda won her fifth consecutive event at last year's Chevron. The difference this year, she said, is that the putts aren't falling.
