Okinawa's Koki Eto failed in his bid to win the WBC super flyweight title on Saturday, losing on points to Mexico's unbeaten title-holder Carlos Cuadras.
The 27-year-old Cuadras finished the fight ahead on all three judges' cards (117-111, 117-111, 116-112) having largely dominated most of the entertaining 12-round slugfest.
"I was aiming to knock him out, but his resilience prevented that," said a jubilant Cuadras after the fight. "He has agility and he's a good fighter."
