The 1998–99 season of the Philippine Basketball League (PBL).
PTV 4, in partnership with Silverstar Sports as the line producer, covered the PBL games.
Tanduay scored a 3–0 sweep over Red Bull in the 1st Yakult-PBL Centennial Cup finals. The Rhum Masters clinch the title with a 71-65 victory in Game three.[1]
Tanduay Rhum Masters strung up 18 straight victories (18-0) in the 2nd Yakult-PBL Centennial Cup, before newcomer Blu Detergents halted their winning run. Tanduay wound up with a 19–1 win–loss record going into the finals.
Dr.J/ANA Water Dispenser won their first-ever PBL crown with a 3-2 series win over Tanduay and denied the Rhum Masters on what could have been a grand exit for the multi-titled ballclub as the Lucio Tan franchise leaped to the pro ranks.[2]
A PBL All-Star game was held in December 1998, Tanduay's Eric Menk leads the PBL-UAAP selection while Asi Taulava of Blu Detergent beef up the PBL-NCAA Hapee selection. The North vs South All-Star game had Yakult-South being coach by Leo Austria while the North All-Stars was handled by Gabby Velasco.
PBL Commissioner Yeng Guiao came up with the formation of the first-ever women's league in the PBL in mid-October to spice up the 2nd conference, among the teams which participated in the Women's Philippine Basketball League are Dr J/Ana Dispenser, Dreyers Ice Cream, Welcoat Paints, Ever Bilena, Tanduay, Chowking and Paralux/Ironcon. Notable WPBL cagebelles were former RP team members Mitchell Jimenez (Paralux), Ana Marie Tinasas (Dreyers), Joanna Franquelli (Ana Dispenser), Mary Ellen Caasi and Cherry Maralit (Welcoat), and four-time SEA games campaigner and silver medal winning-RP team in the Chiang Mai games, Julie Amos of Ever Bilena.
On December 28, 1998, Ever Bilena won the first Birch Tree-Women's PBL crown with a nail-biting 52-51 victory over Chowking at the Makati Coliseum.[3]
