Purefoods struggled in the 1999 PBA season All-Filipino Cup despite acquiring Filipino-American Al Segova and a new head coach in Derrick Pumaren. During the Commissioner's Cup, Codiñera was traded to Mobiline for Andy Seigle. The trade ended the long-time partnership of Patrimonio and Codiñera, who was known as the "Defense Minister." Segova was later banished after he was proven to be a fake Filipino-American. Purefoods failed to get past the quarterfinals of the first two conferences. They were ousted by Alaska Milk in a 3-game sweep despite finishing first at the end of the elimination round with a 7–1 card and lost their last 4 games after winning 6 in a row (8–1 record after the quarterfinals) in the season ending Governors' Cup. Derrick "The Flight" Brown led all imports in scoring and rebounding but was edged out by San Miguel import Lamont Strothers in the balloting for best import honors.
