Fans, players and staff of Racing Club celebrated long into the night on Sunday after La Academia secured its ninth national league title of the professional era, after a 1-1 away draw against Tigre.
For Racing, one of the traditional five giants of Argentine football, it was the team's second title in the tournament in five years. The traditional light-blue-and-white club have 18 national league titles overall, including those from the amateur era.
The team from Avellaneda, on the outskirts of Buenos Aires, lifted the league title with one game in hand after second place Defensa y Justicia drew 1-1 with Unión de Santa Fe.
Sunday's results kept the distance between the top two to four points, with Racing on 56 and Defensa y Justicia on 52.
Racing opened the score at the Estadio José Dellagiovana thanks to midfielder Augusto Solari on 57 minutes. Tigre levelled in the dying seconds of the match with a free kick by defender Lucas Rodríguez.
Racing's title-winning campaign racked up 17 wins, five draws and only two defeats in 24 matches. The champions will face second place Defensa y Justicia in the last round of the tournament, which just weeks ago looked like it would be a title deciding clash.
