Primero Mayo edged past Real Potosí 2-1 in the Nacional B semi-final, a result that aligned closely with the Lemeister model's pre-match assessment, which gave the home side a 38 percent win probability against 30 percent for the visitors. The final margin of a single goal reflected a contest decided by efficiency in both penalty areas, though the absence of detailed shot and expected goals data in the match report limits the depth of analysis available to explain precisely how that efficiency was achieved.
The opening goal of the match was scored by Primero Mayo, giving them an early advantage they would not relinquish, though no assister or build-up details are recorded. Real Potosí responded to level the score, demonstrating their ability to trouble the home defence and create a clear scoring opportunity. However, Primero Mayo reclaimed the lead before half-time, restoring their advantage and taking a 2-1 scoreline into the interval. The second half produced no further goals, with the home side managing the game effectively to secure their place in the final.
Without possession statistics, shot counts, expected goals figures or passing data in the structured information, it is impossible to determine which team controlled the territorial or creative aspects of the contest. The final score suggests a tight, competitive affair where both sides had moments of promise, but only Primero Mayo converted their opportunities with sufficient regularity. The absence of any cards implies a disciplined contest with few disruptive incidents, allowing the flow of the game to be shaped by technical and tactical superiority rather than set-piece or disciplinary interruptions.
No substitutions were recorded for either side, indicating both managers kept faith with their starting line-ups throughout the 90 minutes. This suggests a high level of trust in the players selected from the outset, and that neither coach felt compelled to change the structure of their team during the match. Player match ratings are also absent from the provided information, making it impossible to single out individual performers by number or to identify which players had the greatest influence on the outcome.
For Real Potosí, the defeat ends their semi-final campaign after a season that saw them reach this stage of the Nacional B competition. The single goal they scored indicates they created enough to trouble the home defence and to force the match into a period of uncertainty. However, the final 2-1 margin reflects a failure to convert further opportunities when they arrived, leaving them to reflect on what might have been with only a single strike to show for their efforts.
The result sends Primero Mayo into the final of the Nacional B, a significant achievement for the club. Their path was projected as the narrowest of favourites by the Lemeister model, with a 38 percent win probability compared to 32 percent for a draw and 30 percent for a Real Potosí victory. The actual outcome aligns closely with that pre-match read, reinforcing the model's assessment that this was a finely balanced semi-final. Primero Mayo will now await their final opponents, knowing their semi-final performance, built on two well-taken goals and a disciplined defensive display, gives them a platform to compete for the title. For Real Potosí, the post-mortem will focus on the moments at either end of the pitch where the game was won and lost, and on their inability to find a second equaliser when the match remained in the balance.
