Tigre tame San Lorento
Tigre beat nine-man San Lorenzo 3-1 to move a point behind Clausura leaders Boca Juniors.
The hosts were two ahead through Ezequiel Maggiolo (36) and Roman Martinez (55) when San Lorenzo hit back through Leandro Romagnoli (63). But sendings off for Enzo Kalinski and Walter Kannemann ended their hopes of a comeback and Martinez added his second five minutes from time.
All Boys defeated 10-man Estudiantes 3-1. Eduardo Dominguez (33) and Jonathan Ferrari (49) scored for All Boys only for Estudiantes to pull one back through Gaston Fernandez despite Sergio Modon's red card on the hour. Mauro Matos completed the scoring in the 74th minute.
Struggling Olimpo moved one point above bottom club Banfield following their 2-2 draw with Lanus. Lanus were two up after Mario Regueiro's brace but Andres Franzoia (52) and Martin Guedes (77) levelled things.
Belgrano Cordoba went down 2-1 at Godoy Cruz. Alvaro Navarro and Ruben Ramirez netted in the first half, with Claudio Perez hitting a 90th-minute consolation from the penalty spot.
