BELMONT, Mich. (AP) -- Her ailing back a bit better, defending champion Lexi Thompson shot a 5-under 66 on Saturday for a share of the Meijer LPGA Classic lead with In Gee Chun.
Thompson birdied five of the first 13 holes at Blythefield in her bogey-free round to match Chun at 15-under 198. The 21-year-old American birdied three of the four par-5 holes and is 9 under overall on the par 5s.
Thompson won the Honda LPGA Thailand in February for her seventh LPGA Tour title. The long-hitting Florida player, ranked fourth in the world, also won a Japan LPGA event last month.
