INDIANAPOLIS (AP) Lydia Ko shot an 8-under 64 on Friday to join Lexi Thompson atop the Women in Tech Championship leaderboard with one round left at Brickyard Crossing.

Winless in more than a year, the 20-year-old Ko had five straight birdies in the middle of her final nine before bogeying the par-4 eighth. Thompson followed her first-round 63 with a 66, scrambling for par on the final two holes to match Ko at 15-under 129.

Candie Kung was a stroke back after a 64.

Sandra Gal was tied with Kung at 14 under, then bogeyed the par-3 15th and hit two drives into the water on the par-4 16th en route to a 10. She finished with a 73 to drop eight strokes behind the leaders.
