He is a two-time golden boot winner, having won the award whilst at River Plate and most recently at Nacional in Uruguay's Primera División.

[2] He was joint leading-goal scorer of the tournament along with Danubio's Christian Stuani, establishing a new domestic record which prompted Uruguayan agent Paco Casal to buy the rights of Porta's contract for $1.1 million.

In July 2009 Porta was loaned to former club River Plate de Montevideo where he replaced striker Henry Damián Giménez who left for Bologna.

[10] On 21 October River Plate faced San Lorenzo in the next round of the Copa Sudamericana as Porta played 87 minutes of the 1–0 loss.

[12] Progressing to the semi-final stage of the Copa Sudamericana, Porta put River Plate 1–0 in front after nine minutes against LDU Quito as his side claimed a 2–1 victory at the Estadio Centenario on 12 November.

[18] On 16 February Porta debuted for Nacional at the 2011 Copa Libertadores in a 2–0 loss to Mexico's Club América when he was substituted onto the field on 46 minutes for Nicolás Vigneri.

[21] Three days later Porta was substituted onto the field for Maximiliano Calzada on 64 minutes in Nacional's 1–0 Copa Libertadores win against Argentinos Juniors.

[27] After five games of the Torneo Apertura, in October 2011, Porta announced that he was joining Diego Maradona in his new club Al Wasl FC in Dubai, the United Arab Emirates.

On 11 July 2012, it was reported that Porta had rejected an offer in England in favour of a two-year multimillion-dollar contract with UAE Pro-League side Dubai Club.

[37] By 16 January 2008 it was again reported by The Age that Pim Verbeek was poised to invite Porta to join the squad for Australia's 2010 FIFA World Cup qualifiers.

[39][40][41][42][43] On 7 November, Holger Osieck stated in an interview that the paperwork to officially enable Porta to play for Australia was underway and that clarification from The Uruguayan FA and FIFA was imminent.

According to the Sydney Morning Herald, Porta effectively cut ties with the Australian national team; this came after he was repeatedly stood up by the FFA, despite clearly voicing his interest in playing for Australia.
