Despite a goalless draw with Belgrano, Boca Juniors remain six points clear at the top of the Apertura table as the chasing pack all failed to pick up results. Racing Club managed a draw at San Martin, Atletico Rafaela were soundly beaten by Estudiantes, while Colon and Tigre could only muster draws.
The weekend began with Tigre's trip to Olimpo, where a draw seemed to be on the cards from the off as the hosts had drawn their previous two home matches and have shared the spoils in six of their 11 matches so far. Olimpo took the lead 15 minutes from time when Arturo Aquino arrived unmarked at the back post to lash home, but Javier Carrasco made it 1-1 five minutes later, nipping in front of his man to turn home at the keeper's near post. Newell's Old Boys drew 0-0 with Arsenal in an encounter that lacked goalmouth action but attempted to make up for it through physicality; Lucas Bernardi (Newell's) and Ivan Marcone (Arsenal) were both sent off after 31 minutes for their part in a fracas, and in the 77th minute Guillermo Burdisso (Arsenal) was also sent off for a dangerous tackle on Ricardo Noir.
San Lorenzo's match with Banfield saw an opportunity for either side to pick up valuable points, with both teams languishing in the wrong half of the table after poor starts to the campaign, and it was San Lorenzo who came away with the victory courtesy of Juan Manuel Salgueiro's 71st minute finish, lashing a loose ball past the keeper from just inside the penalty area. Independiente picked up a 2-1 win against Godoy Cruz, going in front just after half time when Leonel Nunez tapped home from a matter of yards after excellent work by Matias Defederico to set up the chance. Ruben Ramirez equalised after 63 minutes for Godoy Cruz, somehow turning home from close range after an awful mistake by Rojo keeper Fabian Assman, but the keeper's blushes were spared when Marco Perez put Independiente back in front in the 89th minute with a delicate finish.
Union and All Boys shared a 1-1 draw on Saturday; though the visitors were in front after just seven minutes through Fernando Sanchez, Union were level on the half hour mark when Paulo Rosales slotted home from the penalty spot. San Martin and Racing Club also shared the points in a goalless draw that did no favours to Racing's hopes of catching Boca Juniors at the top of the table. Estudiantes comfortably overcame Atletico Rafaela 3-0 to record just their second win of the campaign. Gaston Fernandez opened the scoring in the 23rd minute, rounding the keeper and finishing comfortably after neat build up play, before Mauro Boselli doubled the lead after an hour with a diving header at the back post. The points were sealed when Fernandez notched his second, a magnificent strike that flashed into the top corner from 25 yards, with 20 minutes remaining.
Argentinos Juniors and Colon drew 0-0 in a dour game that saw both sides play with 10 men for 78 minutes after Federico Higuain (Colon) and Miguel Angel Torren (Argentinos) were sent off, while Boca Juniors and Belgrano also played out a goalless draw. The final game of the weekend saw Velez Sarsfield come from behind to win 2-1 at Lanus. The hosts went ahead through Diego Valeri's 34th minute penalty, but Hector Canteros equalised just before half time for Velez with a superb curled finish from outside the penalty area. Diego Braghieri was shown a red card for Lanus after 73 minutes, and Velez made their numerical superiority count when, in the 87th minute, Fernando Ortiz found a late winner.
