**Anna Leigh Waters enters the Veolia Arizona Open as the clear top seed in women's singles on the PPA Tour, carrying a dominant recent form and an extended winning streak that positions her as the heavy favorite to advance deep.** The Mesa event, running September 14–20 at Arizona Athletic Grounds, features a wide-open draw with several top players absent, elevating opportunities for seeded challengers. Round-of-16 matches are underway or imminent as of September 17, with quarterfinals scheduled for September 18. Waters faces a favorable early path, while players such as Kaitlyn Christian, Kate Fahey, Brooke Buckner, Lea Jansen, and Zoey Wang navigate tougher sections that include potential early clashes with in-form challengers like Sofia Sewing. Recent results highlight Waters' consistent edge in head-to-heads, though upsets remain possible given the competitive depth and single-elimination format. Trader consensus reflects these form and seeding dynamics in implied probabilities for quarterfinal advancement.
