The Mar del Plata classic had not been played for 27 years due to violent antecedents. It will be played again in the second round, with the home field reversed.

The match had no goals, but it did have controversies. El Tiburón was close to opening the scoring when near the end of the first half, Alan Sosa kicked a free kick that passed close to the goal. In the next, all of Alvarado claimed a penalty for a hit by Gonzalo Soto on Guido Vadalá that referee Nazareno Arasa did not validate.
