Competition moves toward the true grit with men's head-to-head matchups locked in following an electric Day 4 at the EDP Ericeira Pro presented by Estrella Galicia. The swell continued to pulse and the men's top seeds took full advantage of the opportunity at hand with more dominant showings alongside early event threats making their surge to finish the Round of 64 before moving directly into the Round of 32. Kanoa Igarashi tapped into his world-class form with the event's best performance so far, former CT standouts Callum Robson, Miguel Pupo, and Alejo Muniz all surged toward the Round of 16. But the likes of Ryan Huckabee, Joel Vaughan, and more are right on their heels and ready to fight for their place among the Challenger Series rankings.
