INDIANAPOLIS (AP) Lexi Thompson shot a 9-under 63 on Thursday to take a one-shot lead over Sandra Gal and Kris Tamulis in the LPGA Tour's inaugural Indy Women in Tech Championship.
Thompson had 11 birdies and two bogeys to fall a stroke short of the Brickyard Crossing record set by Mike McCullough in the PGA Tour Champions' 1999 Comfort Classic.
Gal, like Thompson, started her morning round on the back nine that features four holes inside the famous Indianapolis Motor Speedway. The German hit 12 of 14 fairways in regulation, avoided the bunkers and finished without a bogey.
Tamulis had the best afternoon score with four birdies on each side.
The 54-hole event ends Saturday.
