Jeeno Thitikul took advantage of favorable weather conditions to shoot a 69 and secure a three-shot lead at the Mizuho Americas Open in West Caldwell, New Jersey. After a challenging front nine, Thitikul closed strong with four birdies in her last seven holes, bringing her total to 8-under 136. Jennifer Kupcho, who finished with a 15-foot par save on the 18th, sits three shots back at 5-under 139. The course presented difficulties, particularly with tough pin placements on undulating greens, which contributed to higher scores for many competitors. Lydia Ko managed a 75, leaving her six shots off the lead, while Andrea Lee fell significantly after a rough front nine, finishing with a 79. Notably, tournament host Michelle Wie West missed the cut after rounds of 82 and 80. The competition features 24 top players from the American Junior Golf Association, and the cut was made to 50 and ties.
