Anna Leigh Waters enters the Veolia Arizona Open as the clear frontrunner in women's singles, backed by her extended unbeaten streak and status as the top-ranked player on the PPA Tour. Recent draws place her in a favorable position with a path that avoids early clashes against top challengers, while her consistent performance across recent events—including multiple finals wins and triple crowns—reinforces trader expectations reflected in the 60% implied probability. Other contenders such as Kate Fahey, Kaitlyn Christian, Brooke Buckner, and Lea Jansen occupy the next tier based on current rankings and draw seeding, though each faces tougher roads in the bottom half or must overcome historical head-to-head deficits. The wide-open nature of the bracket and triple-digit heat in Mesa add situational variables, but Waters' form and experience continue to anchor market positioning ahead of round-of-32 and later stages.
