Sarah Schmelzel and Amy Yang share the lead at the KPMG Women's PGA Championship after strong performances in the second round, both sitting at 6-under par. Schmelzel carded a 5-under 67, marking six birdies and one bogey, while Yang's bogey-free 68 helped her overcome a back issue. Schmelzel attributed her success to patience and aggressive driving, while Yang found increased focus despite her back pain. Former world No. 1 Nelly Korda missed the cut after a disappointing 81, marking her third consecutive missed cut in a major. First-round leader Lexi Thompson, Jin Young Ko, and Hinako Shibuno are two strokes behind the leaders. Celine Boutier, known for her 2023 victories and major win at the Amundi Evian Championship, relies on PXG equipment, highlighting its impact on her performance.
