Olimpo moved up two places to fourth in the Clausura standings thanks to a 1-1 draw away to Lanus on Monday night.
Lanus looked set to continue their 100 per cent home record from five games when substitute Silvio Romero put them in front in the 77th minute, just three minutes after coming on.
However, Olimpo rescued a point thanks to Juan Cobo's 89th-minute effort.
