CHONBURI, Thailand -- Lexi Thompson shot an 8-under 64 Saturday in the third round of the LPGA Thailand to establish a four-stroke lead over Korean In Gee Chun at Siam Country Club.
The fourth-ranked American fired nine birdies - against a lone bogey on the 16th - for an overall 16-under 200.
"I missed a putt on the first hole which got me down a little bit, but I tried to stay positive going into the next hole and fire at pins like I did the first day," said Thompson, who is chasing her seventh LPGA Tour career victory.
