Spain's Iyana Martin has been the tournament's most efficient scorer, averaging 16.5 points per game with a 51.9 TIB rating—the kind of inside-out threat that forces rotations and punishes hesitation. Against a USA side built on ball movement and depth, Martin's scoring gravity becomes the fulcrum. Breanna Stewart, running at 47.1 TIB efficiency with 9.8 points and 2.8 assists in recent outings, remains the counterweight—a wing who reads space and relocates with timing that frustrates pick-and-roll offenses. Stewart's work away from the ball has been as valuable as her scoring; the question for Spain's defense is whether Martin's individual offensive load leaves enough cover for Spain's perimeter. USA's roster depth means Stewart doesn't have to do it alone, but her decision-making and spacing are core to how the Americans build walls. Spain and USA tip off now.
