Guerrero/Navarro enter as the more structured pair: Navarro’s left-side control and experience should stabilize rallies and create finishing patterns for Guerrero. Gutierrez/Oria can compete if they speed up points and win the first volley exchange, but over a full match Brussels’ typically slower indoor conditions favor the team that defends and builds patiently. Prediction: Guerrero/Navarro in 2 tight sets, with a decisive break late in each set.
