Vilarrubí was 17 when he began playing Davis Cup tennis for Uruguay. His deciding rubber win over Pablo González handed Uruguay a tie against Colombia in 2003. In addition to the Davis Cup he also represented Uruguay in the Pan American Games and the South American Games. He won both of Uruguay's gold medals at the 2002 South American Games in Brazil, the singles and doubles events, partnering Marcel Felder in the latter. His last Davis Cup match was played in 2007 and finished with a 10/8 overall record, from 11 ties. In 2003 went to two simultaneous surgeries while living in Barcelona and training under the arms of Francis Roig and Jordi Vilaro that put him away long time from the courts.
