Primera champions Boca Juniors were made to work much harder than expected in their Copa Argentina clash with Nacional B outfit Guillermo Brown but eventually sealed a place in the last 16 thanks to Darío Benedetto’s second half penalty.
Despite dominating possession as expected, Boca failed to carve open their lower league opposition and this lack of incision in the final third not only boosted Brown’s confidence but frustrated Guillermo Barros Schelotto’s side.
With only a few half chances at both ends, the deadlock was broken on the hour mark when Pablo Pérez was tripped driving into the penalty area.
Benedetto stepped up and firmly dispatched the spot kick to the relief of Boca and took his tally in gold and blue to a staggering 29 in 34 matches. Holding on to the 27-year-old and increasing his release clause may have been the best business Boca did throughout the window.
Guillermo Brown couldn’t muster an equaliser and so Boca took their place in the last 16. Rosario Central, a side that Boca have shared recent history with in competition, are up next.
