Sanz/Nieto come in as the more established P2 pairing with clearer role distribution and higher baseline in transition, which usually translates into steadier scoreboard pressure. Wakim/Zaghloul can be dangerous if they turn it into fast, flat exchanges and win the first volley battle, but over a full match the Spanish duo should control net time and minimize errors. Prediction: Sanz/Nieto in 2, with a tighter set if conditions play quick.
