The rivalry is said to have begun even before Purefoods entered the PBA . Ginebra playing coach Robert Jaworski had a simmering feud with former Toyota teammate Ramon Fernandez . The hostilities between two of the biggest stars in the league during that time started to peak in the 1986 PBA season . Jaworski 's Ginebra and Fernandez 's Tanduay Rhum Makers battled each other in the All-Filipino Finals . Fernandez led Tanduay to a 3 – 1 victory against Ginebra , but Jaworski would get his revenge when his team ended Tanduay Rhum 's grandslam bid with a 151 – 130 rout in the season 's third conference . Since then , whenever teams of Jaworski and Fernandez meet , the fans anticipate greater physicality and intensity because of their apparent hatred for one another . The Tanduay PBA franchise was eventually bought by Purefoods in 1988
