Stupaczuk/Yanguas come in as the more established top-tier pair, with higher pace, tighter transitions, and better clutch patterns in P1-level pressure moments. De Pascual/Rodríguez can compete by slowing the match and forcing long left-to-left rallies, but they’ll need near-perfect lob quality to avoid getting pinned. In Buenos Aires conditions, I favor Stupaczuk/Yanguas in 2 tight sets unless the underdogs dominate the lob-battle.
