Yeng Guiao - First Coaching Stint

First Coaching Stint

Prior to his PBA coaching career, Guiao was the head coach of the Swift franchise in the Philippine Amateur Basketball League with Alvin Patrimonio as one of its top stars. The RFM franchise entered the PBA in 1990, as Pop Cola, joining market rival Pepsi. Guiao was the team's first head coach and led the renamed Diet Sarsi to its first finals appearance, losing to the Purefoods Tender Juicy Hotdogs in the 1991 All-Filipino Finals.

In the 1992 Reinforced Conference, he led Swift to their first championship with a 4-0 sweep of 7-Up in the championship. It was also Guiao's first championship in the PBA. He would also led the Mighty Meaties squad to two finals appearances in 1993 and 1994, losing to San Miguel and Alaska.

In 1995, Guiao and then-Pepsi mentor Derrick Pumaren were involved in rare coach for coach trade. While Pumaren led the rechristened Sunkist Orange Juicers to two championships that year, Guiao had two forgettable seasons with Pepsi and then-renamed as Mobiline before leaving his coaching position in 1996.
