Men's basketball games between the two in the UAAP are the most anticipated match-ups in the season, with most games being sold out. Both teams are guaranteed to face each other at the elimination round (regular season) twice, while they can meet for a maximum of three times in the playoffs (up to three times in the semifinals, or twice in the semifinals plus a seeding playoff). The games were played consistently from 1986 until 2006 when La Salle was suspended for fielding two ineligible players. Official UAAP league records since 1986 show that head-to-head championships between the teams have Ateneo leading 4 championships to 2. Including regular season, Final Four and Championship games in the UAAP, Ateneo leads 52 games to 37 as seven La Salle wins from 2003 to 2005 were forfeited due to the use of ineligible players using falsified documents. For comparison, these are the rankings of these two teams since the Final Four format was introduced. In terms of total collegiate and high school volleyball titles won in the NCAA and UAAP, La Salle leads with 42 championships compared to Ateneo's 15 championships.
