One of the first matches he played was a friendly against Numancia on 23 July 1911, and some sources state that he is the youngest player in history to wear Europa's shirt, but it's not known for sure due to the lack of information.

[2] At Europa, he formed a partnership with the Pelaó brothers (Estebán and Bonaventura) and continued to score prolifically for the club, unfortunately, and due to the little statistical rigor that the newspapers had at that time, we know nothing about his goalscoring records with Europe.

[2] His goalscoring records eventually drew the attention of Barcelona, who signed him in 1915 in what is considered one of the first major transfers in Europe,[3] because at the time, club changes, especially of the main star players, were not too common.

[2] With Barcelona he won 5 Catalan championships in 1915-16, 1918-19, 1919-20, 1920-21 and in 1921-22, along with two Copa del Rey titles in 1920 and 1922, with Martínez scoring the opening goal in the former final.

[2] He was summoned by the Catalonia national team for 9 games, where he would score 4 goals, including the winner against a Paris XI on 1 November 1925, two years after he had already retired from football.
