the Ateneo campus in Intramuros to play basketball with the Ateneans, which led to Ateneo forming the first organized cheering squad and pep band in the Philippines and what is now known as the Blue Babble Battalion. This would later become "UAAP's Battle of Katipunan" when both universities transferred to their respective campuses along Katipunan Avenue in Quezon City, and when the two schools began competing in the UAAP. Ateneo–La Salle Arguably the most popular rivalry in Filipino sports was forged in the NCAA: the Ateneo–La Salle rivalry. Historical records are unclear on when the rivalry began, although there are arguments pointing to La Salle's 1939 defeat of a top-seeded Ateneo basketball team and their being dethroned by the Ateneans who beat the Lasallites in the elimination round. While La Salle held their victory parade, they threw fried chickens at the Padre Faura gate of the Ateneo. However. the La Salle cage team was disbarred for fielding an ineligible player the following year (although the title would not become Ateneo's until 1941, two years after the defeat). Ateneo–La Salle games were always heated, for both schools were exclusively for males. However, La Salle during its stint in the NCAA was not as strong a contender as Ateneo was (see Ateneo–San Beda rivalry), with Ateneo not meeting La Salle again until the 1958 Finals, where Ateneo prevailed. Ateneo–La Salle games are now some of the most anticipated games of the UAAP season. Ateneo–San Beda With the departure of University of the Philippines, the Ateneo de Manila and San Beda College fielded the dominant basketball teams for several seasons, having won the last six titles between them. It was in this context that the fierce rivalry between the Ateneo and San Beda emerged. The two teams traded championships in the 1930s that was halted when La Salle scored an upset over Ateneo in the 1939 season. By the time World War II began, Ateneo already had the most number of NCAA senior's basketball titles with six, whereas San Beda had five titles to its name. The ensuing years saw the two schools trade championships and end one another's winning streaks. The rivalry between the Blue Eagles and Red Lions continued and there were memorable games in the 1950s that ensued between the two teams. Carlos Loyzaga's San Beda Red Lions toppled the Ateneo Blue Eagles from 1951 to 1952. Then, the Blue
