Racing, Colon stay undefeated
Racing Club eased to a 3-0 victory at home to Godoy Cruz to join the log jam of teams on four points after two Apertura matches on Wednesday.
Only Lanus have won both their fixtures, with five clubs managing a win and a draw.
Racing took the lead through Teofilo Gutierrez in the 11th minute and the result was never in doubt when Leonardo Sigali saw red for Godoy with just 21 minutes down.
Lucas Castroman and Gutierrez, again, added the gloss before the hosts also lost a man - Gabriel Hauce seeing red in the final minute.
Colon Santa Fe also have four points after a 1-1 draw with All Boys. Mauro Matos gifted Colon the lead when he diverted the ball past his own goalkeeper in the 14th minute but made amends with a 74th-minute equaliser.
Belgrano Cordoba and Olimpo drew 1-1 after Franco Vazquez (55) cancelled out the opener from Martin Rolle (8).
