Millonarios beat Boston River 4-2 in Montevideo on a night that turned sharply after a difficult spell at the Centenario. Rodrigo Contreras scored twice, Leonardo Castro converted from the penalty spot and Beckham Castro added the last goal in stoppage time to seal a comeback that left the Colombian side with seven points.
For long stretches, Millonarios looked as if they might leave the match with more frustration than reward. Boston River pushed them through several uncomfortable moments, but the second half brought a stronger attacking reaction from Millonarios and changed the shape of the game. The penalty that brought the visitors level came before the final surge, and Beckham Castro's added-time finish closed out a result that had seemed far less certain earlier in the night.
The win matters because it tightened the group. Millonarios finished on seven points, the same total held by O'Higgins while Sao Paulo was drawing, leaving little room between the teams near the top of the table. In a match framed as a comeback in Montevideo, Millonarios did what they needed most: they absorbed pressure, found their response and left with control of their fate sharpened rather than blurred.
