[4][5] Being the son of a well-off family in Valls, Mallorquí was sent to France to complete his studies, and while there, he developed a deep interest in football, playing this sport with CU Sportive Marais and Crédit Lyonnais in 1911–12.

[4] He returned to his homeland in 1912, at the age of 18, and in that same year, he joined the ranks of FC Espanya de Barcelona,[3][4] where he formed an attacking partnership with Gabriel Bau and Antonio Baró, and quickly became a key element of the team.

[2][3] At Barça, Mallorquí was mostly used as a substitute by then coach Jack Greenwell due to the presence of Vicente Martínez, Paulino Alcántara, Enrique Peris, and his former teammate Bau.

[5][4][9][10] Like many other FC Barcelona and RCD Espanyol players of that time, Mallorquí was eligible to play for the Catalan national team, scoring two goals in 9 matches between 1915 and 1921.

[11] On 10 July 1927, Mallorquí was the subject of a tribute match along with José Maria Canals, which took place at the Sarrià Stadium between Catalonia and RCD Espanyol, playing for the former in a 1–4 loss.
