Almirante Brown edged Aldosivi 1-0 at the Estadio Fragata Presidente Sarmiento, a result that the Lemeister model had not anticipated as the most likely outcome, having given a home win only a 35% probability against a 38% likelihood of a draw. The single goal, scored by S. Gauna in the 33rd minute, proved decisive in a contest where the underlying numbers likely pointed to a tight, low-scoring affair, even though the specific statistical breakdown for this fixture is absent from the available data. The clean sheet for the home side suggests a disciplined defensive structure, one that absorbed any pressure Aldosivi were able to mount. The visitors, who entered the contest as the underdog with a 27% pre-match win probability per the Lemeister model, were unable to find a way through.
The match was settled by Gauna's strike midway through the first half. That goal, recorded as a normal effort and without a credited assist, gave the hosts a lead they would not relinquish. The remainder of the opening period saw the game's only disciplinary incidents, with Almirante Brown collecting two yellow cards in quick succession. G. Errecalde was cautioned in the 24th minute, followed a minute later by B. Cenci. These bookings, arriving just before the goal, indicate a brief period of defensive urgency from the home side that did not disrupt their overall structure.
Without the full suite of match statistics such as possession, shots, expected goals, and passing accuracy, the tactical narrative must be inferred from the scoreline and the sparse available data. The single goal margin and the clean sheet for Almirante Brown point to a contest where defensive organisation was paramount. The home side likely ceded territory or possession to Aldosivi while remaining compact, forcing the visitors into low-quality chances that did not test the goalkeeper. The absence of a credited assist for Gauna's goal suggests it may have originated from an individual error or a defensive lapse rather than a sustained attacking move.
The two yellow cards for Almirante Brown, both arriving inside a two-minute spell just before the half-hour mark, indicate a brief period of defensive urgency. Errecalde and Cenci were the players booked, and their fouls may have disrupted any developing rhythm from the away side without leading to a numerical disadvantage. The fact that no further cards were issued in the second half suggests the match settled into a controlled, if perhaps cagey, pattern. Aldosivi, needing a response after falling behind, may have increased their attacking intent but lacked the precision to break through.
Player match ratings were not provided, making it impossible to single out individual performances beyond the goal scorer. Gauna's contribution was the solitary moment of attacking quality that separated the sides. The home team made five substitutions to Aldosivi's four, a detail that offers no clear tactical insight but does confirm that both benches were used to try to influence the outcome, likely as the home side sought to protect their lead and the visitors pushed for an equaliser. The substitutions may have helped Almirante Brown manage the game's tempo in the closing stages.
This victory provides Almirante Brown with a valuable three points in the Primera Nacional's Regular Season, Round 24. For Aldosivi, the away defeat represents a missed opportunity to pick up a positive result against a side the Lemeister model considered slightly more likely to draw than to win. The narrow margin of the result underlines how fine the margins can be in this division, with Gauna's first-half goal proving sufficient to decide the contest. The result also highlights the unpredictable nature of the league, where the pre-match favourite to draw failed to secure even a point.
