On May 1, 1995, Manny Pacquiao won a six-round decision over Rocky Palma in Cavite, Philippines, pushing his record to 3-0. They both weighed 107 pounds, but Pacquiao had weights in his pocket to qualify for the minimum weight requirement of the division. Seventeen days later, Mario Barrios was born in San Antonio.
