All Boys secured a 2-1 victory over Deportivo Maipu in the Primera Nacional Regular Season round 26, a result that the Lemeister model had considered less probable. The model gave the home side a 40 per cent win probability and projected a 1-0 home victory, while the visitors entered with only a 25 per cent chance according to its pre-match read. The outcome was defined by All Boys' superior efficiency in the decisive moments, particularly their ability to regain the lead just two minutes after conceding an equaliser.
The opening goal arrived in the 18th minute through F. Toloza, who put All Boys ahead with a normal goal. Deportivo Maipu's S. Moyano was cautioned a minute later, a yellow card that reflected the home side's immediate response to falling behind. The match remained 1-0 until the 70th minute, when F. Rasic equalised for Deportivo Maipu with a normal goal. The home side's joy was short-lived, as All Boys restored their lead just two minutes later through A. Gallo in the 72nd minute. That quick double – conceding and then regaining the advantage – proved the decisive sequence, as Deportivo Maipu were unable to consolidate parity even briefly.
All Boys' discipline was tested in the first half, with A. Tabares booked in the 40th minute, but they held firm. Deportivo Maipu pushed for a second equaliser in the closing stages, but their efforts were frustrated. M. Sosa received a yellow card in the 92nd minute, a late caution that summed up the home side's desperation. Each side made five substitutions, but the changes did not alter the pattern of the contest. Without detailed possession, shot or expected goals data to draw upon, the match narrative is defined by its timing and the efficiency of the three named goalscorers.
The card count was even in terms of numbers – two for the home side, one for the visitors – but the timing of Deportivo Maipu's first booking, so soon after falling behind, suggested a side that was struggling to impose itself. The late yellow for M. Sosa was a symptom of frustration rather than a tactical necessity. All Boys, for their part, demonstrated composure in response to conceding, immediately regaining the lead and then managing the remainder of the match without further incident after Tabares' early booking. The absence of red cards allowed both sides to maintain their full complement, but All Boys used their numerical advantage more effectively in the key attacking phases.
The result is significant in the Primera Nacional context. For Deportivo Maipu, it is a missed opportunity to build momentum at home, particularly after they had fought back to level. The Lemeister model had favoured them as the home side with 40 per cent win probability, and the projected 1-0 scoreline seemed achievable when Rasic struck in the 70th minute. However, their inability to hold the draw for even two minutes exposed a defensive fragility that all three of the home side's bookings hinted at. For All Boys, it is a valuable away victory that strengthens their position in the league table, especially given that the Lemeister model had them as the clear outsider with only a quarter of the pre-match probability. The ability to score twice, including the quick response to Deportivo Maipu's goal, was the difference between the sides on a day when the statistics, limited though they are, show a contest decided by fine margins and the timing of key contributions from Toloza, Rasic and Gallo. All Boys will take confidence from their resilience on the road, while Deportivo Maipu must address their vulnerability after conceding the lead, a pattern that has cost them points in a tight competition.
