So Yeon Ryu takes 1-stroke lead at difficult Lake Merced

DALY CITY, Calif. (AP) — So Yeon Ryu shot a 2-under 70 on Friday afternoon at difficult Lake Merced to take a one-stroke lead over follow South Korean player Sei Young Kim and American Ryann O’Toole in the LPGA MEDIHEAL Championship.

Tied for the first-round lead with Eun-Hee Ji and Anne van Dam after a 67, Ryu chipped in for birdie from the fringe on the par-3 12th, but gave back the stroke with a bogey on the par-4 16th after advancing a chip from deep rough only to the fringe.

Ryu had a 7-under 137 total on the tree-lined course with tricky greens made tougher with shifting wind.

O’Toole birdied three of her last three holes in the afternoon in a bogey-free 65, matching the best score in the first two rounds.

Kim had a bogey-free 66, playing through back pain.
