Bolívar secured a significant away victory at the Arena do Grêmio, stunning hosts Gremio with a solitary goal to clinch a 1-0 triumph in the CONMEBOL Sudamericana. The decisive moment arrived in the 16th minute when Dairon Asprilla, expertly set up by Robson Matheus, found the back of the net, a lead Bolívar would fiercely defend. Gremio, struggling to break down the resolute Bolivian defence, made multiple tactical substitutions throughout the second half in a bid to find an equalizer. The latter stages of the match were marred by a flurry of yellow and red cards, with Gremio seeing Marlon and Erick Noriega sent off in added time, while Bolívar's Leonel Justiniano also received his marching orders in a chaotic conclusion that ultimately saw the visitors hold firm for a memorable win.
