Leygue/Deus project as the steadier, more structured pair, likely aiming to win through disciplined side-to-side construction and controlled net occupation. Martinez/Valenzuela should bring more volatility—bigger first-strike intent and faster point endings—so their chances rise if they keep unforced errors down in Miami’s typically lively, humid conditions. Slight edge to Leygue/Deus over three sets, with margins decided by who controls the right-side tempo and transition game.
