Diestro/Piotto should be the more stable pair over a full match: Diestro’s experience in Platinum-level pressure points plus Piotto’s support play typically beats a less-established Garcia/Jimenez duo in long side-out sequences. In Lisbon’s usually medium-paced indoor-style conditions (controlled bounce, heavier balls), patience and net dominance decide more than raw power. Prediction: Diestro/Piotto in 2 sets if they win the first 8–10 games’ net battles.
