Anna Leigh Waters enters the Veolia Arizona Open as the clear top seed and overwhelming favorite in women's singles, backed by an undefeated PPA Tour streak exceeding two years and superior head-to-head records against the field. The draw places her in the top half with a relatively favorable path, while No. 2 seed Kate Fahey occupies the bottom half alongside Brooke Buckner, Kaitlyn Christian, Lea Jansen, and emerging threats like Sofia Sewing. Recent form, ranking points at stake, and Waters' experience in high-stakes singles finals reinforce trader consensus around her implied probability, though the competitive depth and potential for upsets in later rounds keep secondary contenders in play.
