Mouriño/Quilez project as a steadier, structure-first pair likely to lean on controlled bandejas and low-error patterns, while Leal/Guerrero bring higher pace and more first-strike potential off the return and in transition. In Valencia’s typically quick indoor conditions, the match hinges on whether the favorites can slow exchanges and protect their second serves. Slight edge to Leal/Guerrero if they win the middle (net timing) early; otherwise Mouriño/Quilez can grind it out.
