Segundo Castillo's penalty lifted Ecuador into a 2-2 draw with Argentina in what was a friendly warm-up for the Copa America in Mar del Plata.

Both sides were made up of largely second-string players as they opted to field home-based players and it was the visitors who took the lead through Michael Quinonez. Argentina responded and goals from Claudio Yacob and Gabriel Hauche put them 2-1 up at the break, only for former Everton midfielder Castillo to level from the spot.

Quinonez put Ecuador ahead in the 28th minute. Segundo Castillo's long pass allowed Giovanni Nazareno to get a cross into the box, where the forward beat Juan Pablo Carrizo with a right-footed shot.

Yacob pounced to equalise in the 32nd minute after Ecuador goalkeeper Marcelo Elizaga failed to hold on to a Jonathan Maidana header. Just three minutes later Hauche was set up by Enzo Perez and beat Elizaga to give Argentina the lead, although the hosts were dealt a blow when Yacob limped off injured.

Argentina lost their lead in the 67th minute as the referee awarded a penalty despite Pablo Mouche appearing to have not committed a foul on Castillo, and the midfielder dusted himself off to level and earn a share of the spoils.

The Copa America gets under way in Argentina in July. The hosts have been drawn in Group A alongside Colombia, Japan and Bolivia, while Ecuador will play against Brazil, Paraguay and Venezuela in Group B.
