Diane Parry

Parry is one of very few women on tour with a one-handed backhand, and it shapes everything about how she plays: she slices to change pace, comes forward more than most, and is at her most effective when she can break an opponent's rhythm rather than out-hit them. It makes her a genuinely awkward draw, which is how she beat Mertens from a set down in Cincinnati.

Parry’s one-handed backhand makes her results streakier than her ranking implies — she is capable of beating seeded players and of losing to those well below her. That variance is priced into her outright numbers but not always into individual matches, where the market tends to treat her as a straightforward underdog against a seed.
