Ernesto Rubillar: Boxing Career and Notable Fights
Ernesto “Hard Rock” Rubillar was a Filipino professional boxer from Tagum City in Davao del Norte. PhilBoxing and BoxRec list a career record of 38 wins, 34 losses and seven draws across 79 bouts, including 14 wins by knockout.
A long lower-weight career
Rubillar competed through the minimumweight and flyweight ranges and took part in regional and world-level title contests. BoxRec records one world-title bout, while PhilBoxing’s record documents the broader run of opponents and results.
What the record shows
Rubillar boxed across several lower weight classes and faced opponents in the Philippines and abroad. His listed record documents 79 professional bouts.
National and international belts
Rubillar won the Philippine minimumweight championship against Flash Villacura in April 1999. He later captured the WBC International minimumweight title by stopping Zarlit Rodrigo in the seventh round on February 24, 2001. PhilBoxing’s detailed title record lists two defenses of each belt.
The WBC International reign ended with a split-decision loss to Armando de la Cruz on September 26, 2003. These were national and regional achievements, distinct from the world championship opportunity recorded elsewhere in his career.
A demanding list of opponents
Rubillar’s opponents included Chana Porpaoin, Keitaro Hoshino, Saman Sorjaturong and Rodel Mayol. BoxRec’s career summary also credits him with a victory over former world champion Eric Chavez. The list shows the level of competition he encountered beyond his own championship wins.
His lengthy record combines repeated appearances in the Philippines with overseas contests. That breadth is central to understanding his career: the overall win–loss total includes both successful domestic campaigns and difficult assignments against championship-level opponents. The preserved Porpaoin video provides a view of one matchup within that much wider body of work.
Further career results
His earliest professional record included repeated meetings with Arnold Fernández during 1990 and 1991. Rubillar also beat Kid Hagonoy twice over eight rounds in 1991 and stopped Al Tarazona in two rounds that April. Those domestic appearances preceded his national and international championship campaigns by several years.
