From 1975 to 2003, and again from 2010 onwards, a traditional
Philippine Basketball Association season is composed of three conferences. Currently, these three are the
Philippine Cup,
Commissioner's Cup, and
Governors' Cup. In certain circumstances, the PBA may hold less than three conferences in a season. To pave the way for the Philippines' hosting of the
1981 SEA Games and
2023 FIBA Basketball World Cup, two conferences were held in the
1981 and
2023–24 seasons. Due to restrictions during the
COVID-19 pandemic, the
2020 season was reduced from three conferences to one while only two were held for the following
2021 season. From 2004 to 2009, the league switched to a two-conference format consisting of the Philippine Cup and the import-laden
Fiesta Conference. A Grand Slam can still be achieved by winning both titles but this was never done. As of 2024, the PBA Grand Slam has been accomplished five times by four teams and four coaches since the league's inception in 1975. The
Crispa Redmanizers are the only team to win two Grand Slams while
Tim Cone is the only coach to win two, doing so with the
Alaska Milkmen and
San Mig Super Coffee Mixers in 1996 and 2014, respectively.
Winners 1976 Crispa Redmanizers In the league's second season, the
Crispa Redmanizers became the first team to win all of the conference championships in a single season. Before the start of the 1976 season, they had won the All-Philippine Championship, the third conference of the PBA's maiden season. The Redmanizers won all of the 1976 season conferencesthe All-Filipino (reclassified as the First Conference in 2010), the Open (reclassified as the Second Conference), and the All-Philippine Championshipwith an overall season record of 47–15. All of their championships were won against the
Toyota Comets, who have been
the Crispa Redmanizers' rivals since both teams played in
MICAA. The Crispa Redmanizers' team was composed of future Hall of Famers
Bogs Adornado,
Atoy Co,
Abet Guidaben, and
Philip Cezar, and was coached by
Baby Dalupan.
1983 Crispa Redmanizers Crispa Redmanizers achieved the Grand Slam again in the 1983 season. The team still comprised many of the same players as the 1976 Grand Slam team, but they were now coached by former
U/Tex Wranglers tactician
Tommy Manotoc. Crispa began the season by winning 12 consecutive games in the
All-Filipino Conference, losing only their first game to Toyota in the start of the group stage. They finished the group stage with a 7–1 record, then won all of their playoff games, including their
best-of-five series against
Gilbey's Gin Tonics. The team's winning streak continued into the next conference, the
Reinforced Filipino Conference, as Crispa won their first nine games in the group stage and ended their streak with 21 wins. Also this conference, they hired former
Portland Trail Blazer player
Billy Ray Bates as their import. Crispa Redmanizers have won the conference championship against former Redmanizer Bogs Adornado and the
Great Taste Coffee Makers by
three games to two. In the
Open Conference, the final conference of the season, the Redmanizers again hired Bates as their import. They entered the finals against Great Taste. The Redmanizers again defeated the Coffee Makers in their
best-of-five finals series. Bates won
Best Import of the Conference awards for the Reinforced Filipino and Open Conferences. Abet Guidaben won the
Most Valuable Player award at the end of the season. The San Miguel Beermen also acquired former
Purefoods Hotdogs center and playing coach
Ramon Fernandez, controversially trading him for Abet Guidaben with the Hotdogs. With import Michael Phelps, San Miguel won the
Open Conferencethe first conference championship of the seasonagainst
Formula Shell Zoom Masters led by
Bobby Parks. The Beermen struggled in the group stage of the
All-Filipino Conference but went into the final against Purefoods Hotdogs and won the
championship series in six games. In the final conference of the season, the
Reinforced Conference, the Beermen performed poorly in the group stage and won most of their games in the semifinal round. They advanced to the finals against sister team
Añejo Rum 65ers. They have won their
best-of-seven series against the 65ers in five games. In the first conference of the 1996 season, the
All-Filipino Cup, the Milkmen played the Purefoods TJ Hotdogs in the
best-of-seven finals. In Game 5 of the championship series, Purefoods forced the game into overtime and held a one-point lead against Alaska, 92–91, with 10.3 seconds remaining. In the next play, Alaska was inbounding from their baseline behind the basket. Jeffrey Cariaso caught the ball in an alley-oop attempt but was fouled by Bong Ravena while trying to block the shot with 0.6 seconds left. Cariaso sank both of his free throws and gave Alaska the lead, 93–92. With no timeouts left, the TJ Hotdogs threw a desperate attempt from the opposite side of their basket and missed, giving the Milkmen the All-Filipino championship. In the second conference, the
Commissioner's Cup, the Milkmen hired
Derrick Hamilton as their import for the tournament. After the league found out about Hamilton's marijuana use, the Milkmen hired their resident import
Sean Chambers to replace Hamilton. The Milkmen played against the Formula Shell Zoom Masters in the
finals and won the championship in seven games. In the third and final conference of the season, the
Governors' Cup, the Milkmen played
Barangay Ginebra San Miguel. The Milkmen won their series against the Gin Kings
in five games.
2013–14 San Mig Super Coffee Mixers In 2011, the former Alaska coach Tim Cone took over the coaching duties of the B-Meg Llamados teamlater renamed the
San Mig Super Coffee Mixers. The team's core comprised twice-league MVP
James Yap,
Marc Pingris, and
PJ Simon. In the first conference of the 2013–14 season, the
Philippine Cup, the Coffee Mixers performed poorly in their first games of the tournament and were ranked in fifth place at the end of the group stage. They faced arch-rivals Barangay Ginebra San Miguel in the semifinals and won their series in seven games. They beat the
Rain or Shine Elasto Painters in the finals and won the championship by four games to two. In the
Commissioner's Cup, the Coffee Mixers hired
James Mays as their reinforcement for the tournament. Still struggling in the regular conference, the Coffee Mixers finished in sixth place with a 4–5 record. The team played the defending champions Alaska Milkmen in a best-of-three quarterfinal series. Alaska Milkmen won the first game 86–77, and were on verge of eliminating the Coffee Mixers. The Coffee Mixers won the next two games to advance to the semifinal round against
Air21 Express, an unexpected semifinalist who had eliminated the second-seeded San Miguel Beermen, who had
twice-to-beat advantage (equivalent to a 1–0 lead in a
best-of-three series). Air21 Express, led by
Asi Taulava, won the first game against the Mixers, 103–100. The Coffee Mixers won the next two games; they took the series lead and were one win away from a place in the finals. Air21 Express scored 94 points in Game 4 and forced a rubber match. Game 5 was won by the Coffee Mixers 99–83.
In the finals, they faced the
Talk 'N Text Tropang Texters, who had a 13–0 record before the start of their championship series. The Coffee Mixers won the first game of the series. Talk 'N Text won Game 2 of the finals but the Coffee Mixers won the next two games and their third consecutive championship. In the
Governors' Cup, the Coffee Mixers hired their import
Marqus Blakely as their reinforcement for the tournament. The team finished the group stage with a 5–4 record and tied with Alaska, San Miguel, Barangay Ginebra, and Air21 in third place. Because of the
quotient system imposed for tiebreakers in this conference, the Coffee Mixers were in fourth place, having the second-best quotient among the five teams. The Coffee Mixers defeated fifth-seeded San Miguel Beermen in the quarterfinals in one game (SMC had a twice-to-beat advantage), 97–90. The Coffee Mixers advanced to the semifinal round, where they played their Commissioner's Cup finals opponent the Talk 'N Text Tropang Texters. The Coffee Mixers won the first two games of their best-of-five series, giving them a lead to close the series and eliminate Talk 'N Text. However, the Tropang Texters won games 3 and 4, forcing a deciding Game 5. The deciding Game 5 was very close and no team led their opponent for more than seven points in the first three quarters. In the fourth quarter, the free-throw shooting problems and missed attempts in Talk 'N Text's paint allowed Coffee Mixers win the game and secure a place in the
finals. They played their Philippine Cup opponents, Rain or Shine. The Coffee Mixers won the series and the Grand Slam after five games.
