Independiente Petrolero edged Gualtberto Villarroel 1-0 in the Apertura's fifteenth round on Sunday night. The hosts claimed all three points at home, extending a run that had seen them win two of their last five while the visitors lost their last outing to Always Ready. R. Zamora's twenty-ninth-minute strike proved the difference.
The goal came from a well-worked move that cut through the visitors' defence before Zamora finished from close range. By then the match was already tilting toward tension. The visitors had created more but could not convert, and then came the moment that changed everything. A. Mercado received a second yellow card in the fifty-eighth minute, sending him off and leaving his side to play with ten men for thirty-two minutes.
The statistics tell a story of frustration for the visitors. They held 53 per cent possession and created four big chances compared to Petrolero's one, but their shots on target numbered just two from eleven attempts. Petrolero were sharper, landing four shots on target from eleven attempts. The hosts also completed more passes in their own half and made fewer errors, but what mattered was how they handled the pressure after the red card.
Petrolero now sit fifth with twenty-five points from seventeen matches, two ahead of the teams below them. Villarroel remain sixteenth with fourteen points, and the gap to safety has not narrowed. The visitors had drawn three of their last five before this defeat, but they paid for a sloppy opening and then could not recover once down to ten men.
