The YCO Shine Masters were a Philippine Basketball League (then known as the Philippine Amateur Basketball League (PABL) team that played for three conferences through the 1986 and 1987 seasons, winning two PABL titles.
YCO won the 1986 PABL Third Conference Crown, known as Filipino Cup, at the expense of ESQ-Sta.Lucia Realty.
Other players in that maiden lineup were Ato Agustin and Andy De Guzman.
The following year, the Shine Masters would meet RFM-Swift Hotdogs twice for the championship, losing the first time when the Hotdogs benefited for getting top players like Jojo Lastimosa and Nelson Asaytono from eliminated teams.
YCO gained a measure of revenge over RFM-Swift's the following conference via 3-0 sweep.
