Gil/Sánchez should enter as the more stable, higher-ceiling pair: Gil’s left-side management and Maxi’s control normally produce longer, higher-percentage rallies. Hernández/Collado can threaten with pace and first-strike volleys, but in Gijón’s typically heavier indoor conditions the match often tilts toward patience, depth, and net-occupation discipline. Prediction: Gil/Sánchez in 2, unless Hernández/Collado win the serve-return mini-battles early and shorten points.
