Lizette Salas shot an 8-under 64 on Saturday to take a two-shot lead over Sung Hyun Park and Amy Yang after the third round of the Indy Women in Tech Championship.

The 29-year-old former Southern California player hasn't won on the LPGA Tour since 2014. She took the lead with a birdie on the par-4, 16th — after Park hit her approach into the water en route to a double bogey.
