Grand Slam (PBA) - "The Pretenders"

In addition, several others won the first two conferences but were beaten on the last tournament. They are known as "The Pretenders".

• 1975 Toyota Tamaraws (lost to Crispa in the All-Philippine Championship)
• 1977 Crispa Redmanizers (lost to Toyota in the Invitational Conference)
• 1985 Great Taste Coffee Makers (missed Finals berth in the Reinforced Conference)
• 1986 Tanduay Rhum Masters (missed Finals berth in the Open Conference)
• 1995 Sunkist Orange Juicers (missed Finals berth in the Governors Cup)
• 1998 Alaska Milkmen (missed Finals berth in the Governors Cup)
• 2004 PBA Fiesta Conference to 2004–05 Barangay Ginebra Kings (missed Finals berth in the Fiesta Conference)
• 2010-11 Talk 'N Text Tropang Texters (lost to Petron in the Governors Cup)

In other instances, a team won three or even four consecutive conferences in two different seasons. Purists say this is not a true grand slam. These teams were:

• 1976-1977 Crispa Redmanizers (includes the 1976 All-Philippine Championship which was part of the 1976 Grand Slam)
• 1984-1985 Great Taste Coffee Makers (four straight championships)
• 1995-1996 Alaska Milkmen (four straight championship '95 Governor's Cup and '96 Grand Slam)
• 1997-1998 Alaska Milkmen (three straight championships)
• 2000-2001 San Miguel Beermen (three straight championships)

Also, the 1976 and 1980 Toyota Super Corollas and the 2004-2005 Talk 'N Text Phone Pals have the unfortunate distinction of losing all of the championship series in one season. Toyota lost all three against the Crispa Redmanizers in 1976 and lost to U/Tex, guest team N. Stoodley, and Crispa in 1980. The Phone Pals were defeated by the Beermen and the Barangay Ginebra Kings in the two-conference format.
