Windahl/Vasquez should enter as the steadier, more complete pair: better net management, higher rally tolerance, and more reliable clutch patterns typical of experienced FIP pairs. Richters/Olsson can swing the match with power and fast points, but they’re more exposed if forced into long, diagonal exchanges and repeated lobs. Prediction: Windahl/Vasquez in a tight match, likely in 2 close sets or 3 if Richters dominates serve games early.
