Stupaczuk/Yanguas arrive as the higher-ceiling pair: faster to the net, heavier in transitions, and better equipped to control tempo in a Platinum setting. Diestro/Piotto can make it ugly with volume, lobs, and counterpunching, but they’ll need long rallies and error extraction to keep the favorites off rhythm. Expect Stupa/Yanguas to take over through net dominance and targeted pressure on the less stable wing in key games.
