GRAND RAPIDS, Mich. -- Lexi Thompson shot a 64 on Saturday on the Blythefield layout reduced to a par of 69 because of flooding, giving her a one-stroke lead in the Meijer LPGA Classic.
The fifth hole was played as a 111-yard par 3 instead of a par 5 because of the flooding from overnight rain.
Coming off a playoff loss to Ariya Jutanugarn last week in Canada, Thompson had six birdies and a bogey to reach 15-under 196.
Brooke Henderson, the leader after each of the first two rounds, had a 67 to drop into a tie for second with Lee-Anne Pace (61), Sung Hyun Park (62) and Jenny Shin (63).
Hyo Joo Kim (65) was 12 under, and Lydia Ko (64), Michelle Wie (64), Moriya Jutanugarn (67) and Carlota Ciganda (68) followed at 11 under. Ko dropped to No. 2 in the world Monday after an 85-week run at the top. The top-ranked Ariya Jutanugarn, Moriya Jutanugarn's younger sister, was 9 under after a 64.
Thompson won the Kingsmill Championship last month in Virginia for her eighth LPGA Tour title after losing the ANA Inspiration in a playoff after being penalized four strokes for a rules violation reported by a television viewer.
At Rancho Mirage in early April, Thompson was given the four-shot penalty with six holes to play in the final round. She had a 15-inch putt on 17 in the third round when she stooped to mark the ball, and quickly replaced it about an inch away. The television viewer contacted the LPGA Tour the next day, and officials determined it was a clear violation.
Thompson was assessed a two-shot penalty for where she replaced the ball, and because it happened the day before, she received a two-shot penalty for signing an incorrect scorecard. She went from a three-shot lead to one shot behind, and eventually lost to So Yeon Ryu in the playoff.
