Tigre held, San Lorenzo beats Banfield
Javier Carrasco earned Tigre a 1-1 draw away to Olimpo in Friday night's Apertura action.
Host Olimpo had gone in front in the 73rd minute through substitute Arturo Aquino. However, Carrasco, also on from the bench, found the equaliser with 10 minutes to go.
San Lorenzo earned a 1-0 win at home to Banfield thanks to Juan Salgueiro's 72nd-minute strike, while the day's other match between Newell's Old Boys and Arsenal finsihed goalless.
