The new era at Racing Club got off to a less than auspicious start with Juan Antonio Pizzi beginning his tenure as manager with a 2-0 defeat away to Copa Diego Maradona runners-up Banfield.
Following a goalless first half an Alexis Soto error one minute after the restart allowed Juan Álvarez in behind to rifle a shot past Gabriel Arias.
A rather toothless Racing introduced Lorenzo Megarejo, Nicolás Reneiro along with new signings Tomás Chancalay and Maxi Lovera but it was Banfield that wrapped up the points, Guiliano Galoppo eventually bundling in from close range.
Colón made a winning start to the Copa De La Liga comfortably seeing off Central Córdoba in a wet Santiago del Estero. Copa Diego Maradona leading scorer Luis Rodríguez tucked the Sabalero in front after 12 minutes, 21-year-old Tomás Sandoval poked the visitors two in front just before the hour mark and substitute Nicolás Leguizamón added a third.
While in Santa Fe, Unión twice came from behind to salvage a point from the visit of Atlético Tucumán.
Ramiro Carrera headed Atlético into a 16th minute lead only for young midfielder Martín Cañete to drill in a fine equaliser from the edge of the box.
Debutant Santiago Vergini restored the lead before the break with an unmarked header and it looked to be enough to take all three points until deep in stoppage time when Marco Borgnino produced a wonderful 30-yard free-kick to beat Cristian Lucchetti.
