Magnolia's last two titles in 1990

The 1990 National Open championships drew only seven teams. Magnolia continued its mastery over Sta.Lucia Realtors, whom they beat 3 times in the last five PABL finals series.

Magnolia won the PBL first conference of the 1990 season, which turn out to be the last time they won under the name of Magnolia. The team did win a PBL title under the banner of Instafood Mealmasters in 1994.
