It all comes down to Sunday at Osaka, where Ashlyn Krueger faces Katerina Siniakova for the trophy. Ashlyn Krueger has won 3 in a row and 6 of the last 10 overall. Katerina Siniakova comes in at 5 wins from the last ten.

On paper it's close: comparable ratings, comparable serve numbers, small margins everywhere. This one is close to a coin flip, and the lean toward Krueger is exactly that — a lean.
