RANCHO MIRAGE, Calif. — Lexi Thompson figured young friend Lydia Ko was dead in the woods to the left of the seventh fairway.

“I didn’t know she had that kind of shot because she was on an upslope,” Thompson said. “I didn’t know she could keep it under the trees.”

Trying to tie Annika Sorenstam’s LPGA Tour record for consecutive rounds under par, the 17-year-old Ko was even par with three holes left Thursday in the first round of the ANA Inspiration. And she was stuck behind five large trees.

To escape, she needed to a hit a sweeping, low hook.

She did, with the ball scampering onto the green and stopping pin-high 25 feet to the right.

She closed with a par for a 1-under 71 to match Sorenstam’s record of 29 straight rounds under par.
