**Anna Leigh Waters dominates the top half of the women's singles draw at the 2026 PPA Tour Veolia Arizona Open in Mesa, with her extended winning streak making her the clear frontrunner to reach the semifinals.** The #1 seed faces limited resistance early, while #3 Kaitlyn Christian occupies the same half but has historically struggled against Waters. In the bottom half, #2 Kate Fahey holds strong positioning despite a tougher path featuring #4 Brooke Buckner, #5 Lea Jansen, and #6 Zoey Wang. Unseeded Sofia Sewing stands out as a potential semifinal threat due to her top-10 singles level and favorable early matchups, though she must navigate several ranked opponents. Recent draw analysis highlights the bracket's relative openness beyond Waters, with recent form and head-to-head records shaping trader views on quarterfinal advancement. The event runs through September 20, with main-draw play underway as of mid-September.
