The teams from the Buenos Aires suburb of Avellaneda went into the derby in crisis mode after each suffered three-goal defeats last week.
Independiente, officially at home but playing at Huracan while their own stadium undergoes renovation work, went ahead in the third minute when Lucas Pusineri was able to head in after being given too much room at a free kick.
Daniel Montenegro added the second from a penalty in the 65th minute after Ismael Sosa was upended by Gabriel Mercado.

Juan Arraya put the northerners ahead in the 69th minute and Paraguayan Santiago Salcedo equalised six minutes later.
