Stanford senior Megha Ganne, the No. 2-ranked player in the country, shot four-under-par 68 on Thursday in Round 1 at the Omni La Costa Resort & Spa to be tied for the lead with 125th-ranked Ellie Bushnell (Oklahoma State). Ganne’s result led the top-ranked Cardinal women to a team score of six under, and they trail rival and No. 2 USC by one shot. Ten players were tied at three under, including No. 1-ranked Farah O’Keefe (Texas). The top eight teams after four rounds reach match play, and the current best team in trouble is sixth-ranked Auburn, which shot 14 over and is last in the field of 30.
