Lydia Ko, who won the AIG Women’s British Open at St. Andrews in her last start, shot a third-round 3-under 69 around TPC River’s Bend in Maineville, Ohio, on Saturday and is alone in second, two back of Thitikul’s lead.

Thitikul (16-under overall) had a rocky closing stretch but did enough to expand her lead over Hall of Famer Lydia Ko with a 4-under-par 68.
