Sean Chambers was back anew for the Third Conference and "Mr.Excitement" Paul Alvarez was ready to play and rejoined his new teammates. The Milkmen were on top in Group B after the elimination round with seven wins and four losses. Alaska split their first four games in the semifinals and looks headed for another disappointing finish in search for their first championship as they were lagging behind Ginebra and Pepsi Hotshots in the standings, but just as quickly, the Milkmen bounced back with victories over Tivoli Milk and Ginebra San Miguel.

On November 21, Alaska Milk sealed a championship showdown with Ginebra by defeating San Miguel Beermen, 94-80, in the last scheduled date of the semifinal round for their 12th win in 19 games. Alaska won their first-ever PBA title with a 3-1 series victory over Ginebra San Miguel in the best-of-five series.

• Eugene Quilban was named the season's Rookie of the year.
