In the third conference of the 1990 PBA season, Alaska finally advances in the finals for the third time in franchise history and their first since the 1987 season. Going up against the Purefoods Hotdogs, both teams were gunning for their first championship. Alaska had former Boston Celtic Carlos Clark and Sean Chambers as their imports to be pitted against Daren Queenan and Robert Rose of the Hotdogs. The Milkmen went up 2–0 in the best-of-five title series and on a threshold of winning their first trophy, but Purefoods came back and win the last three games to capture the 1990 PBA third conference crown.
