McIlroy shot an opening 4-under 66 that featured six birdies and long drives. "I certainly can tidy a few things up," he said, "but overall a decent day.”

Shane Lowry remains one of the best overall approach players on the PGA Tour, and he carries a tremendous track record on championship-style venues. With seven top-20 finishes in 10 starts in 2025, the Irishman has been one of the most consistent players on tour this year, and I’m expecting another strong performance at Philadelphia Cricket Club.
