Men's basketball results
After both Ateneo and La Salle left, San Sebastian (frequently shortened to "Baste") strengthened their basketball program. The recruitment of Paul Alvarez by San Sebastian and Samboy Lim by Letran provided several close games in the 1980s which led to the birth of the rivalry.

In the 1980s, Letranites were notorious for yelling profanities at the San Sebastian players, and on one occasion, led to a rumble at Vito Cruz Avenue when at the last second, a power interruption occurred, causing confusion on what team won the championship. The rumbles between the two schools have become more frequent which solidified the intense rivalry between the two schools. Paul Alvarez would later play for the Pennsylvania Valley Dawgs of the United States Basketball League.

The final four was instituted in 1997; prior to that the first and second round winners, plus the team with the best overall standing if it did not win either round, participated in the championship round to determine the champion.

The rivalry continued in the turn of the millennium when the Stags met the Knights in the finals twice. This led to several memorable games in which the Knights won the 1998 edition with a barrage of three-pointers and free way ows by Letran's Nicholas Pacheco with a few seconds remaining to win their 13th championship. The Knights also became the first 4th seed to upset the 1st seed in the Final Four when they defeated the Stags twice during the 1999 NCAA Final Four. That feat would soon be duplicated the following year when the 4th seed Stags upended top seed JRC Heavy Bombers in the 2000 NCAA Final Four. The Knights went on to win the 1999 NCAA championship. In the 2003 NCAA Finals, the Stags (defending champs) made a rally in the 4th quarter in the 3rd game of their series and kept Letran scoreless for almost 6 minutes that led them to take the lead but Boyet Bautista started the comeback by tying the game at 48-all and then his teammates Jonathan Piñera and Aaron Aban finished the game to win their 15th championship at the expense of the Stags. In 2004, they renewed their rivalry in the second round of eliminations wherein Letran denied Baste's Final 4 hopes and eventually broke their streak of Final Four appearances (since the inception of the final four format in 1998 San Sebastian is always in the Final Four) making it their worst performance in 6 years.
