Primera Nacional Matchday 4 Review 2026/27 Season
The fourth round of the Primera Nacional delivered 34 goals across 19 encounters, with attacking football stealing the headlines alongside some resolute defensive performances. Six teams found the net at least twice, with Colegiales leading the charge as the highest scorers of the matchday after their commanding 3-1 victory over Quilmes at home. The round showcased the competitive depth of Argentina's second tier, where clubs continue to balance promotion ambitions with the demands of a gruelling season schedule.
Home advantage proved decisive in several contests, with Almagro, San Telmo, and San Martin S.J. all recording comfortable 2-0 wins on their own turf. However, the away teams were not without their moments, as San Miguel, Chaco For Ever, and All Boys returned from their travels with maximum points. Defensive discipline dominated five other fixtures, where neither side could break the deadlock, resulting in goalless stalemates involving Chacarita Juniors, Deportivo Maipu, and Nueva Chicago among others.
The matchday statistics paint a picture of a league where goals remain within reach but nothing is guaranteed. With 19 teams in each division and the season still in its infancy, positions in the table remain fluid. Clubs will look to build momentum as the fixture list continues to unfold, with both the Prim and Segunda Divisions offering plenty of talking points after this latest round of action.
Matchday 4 Prediction Performance: A Tough Day at the Office
The fourth round of the Primera Nacional delivered a stark lesson in the unforgiving nature of Argentine football's second tier, as our prediction model recorded a modest 33% success rate on 1X2 selections, converting just 6 correct calls from 18 matches. While this headline figure appears disappointing at first glance, the picture becomes more nuanced when examining the broader accuracy metrics, which reveal pockets of genuine competence alongside clear areas for improvement.
The six successful predictions this round came from matches where the home side justified their favourite status with relative comfort. Colegiales dismantled Quilmes 3-1, San Martin San Juan defeated Agropecuario 2-0, Deportivo Madryn overcame Los Andes 2-1, Almirante Brown swept aside Atletico Mitre 3-1, Ferro Carril Oeste edged past Deportivo Moron 1-0, and Club Atletico Guemes fell 1-3 to Gimnasia Jujuy. Each of these outcomes reflected a home win where our model correctly identified the stronger side, suggesting that when the favourite performed as expected, the analysis held firm.
The remaining twelve mismatches painted a more troubling picture. Five predictions pointed toward home wins that never materialised: Temperley and Patronato each settled for draws when home victories were expected, while Acassuso, Defensores de Belgrano, and Nueva Chicago all failed to win despite our forecast. The model also failed to anticipate several away successes, missing San Miguel's 2-0 victory at Acassuso, Colon Santa Fe's narrow loss to Chaco For Ever, All Boys winning at Defensores de Belgrano, and CA Estudiantes prevailing at Ciudad de Bolivar. Central Norte's unexpected 1-0 home victory over Godoy Cruz and San Telmo's 2-0 defeat of Racing Cordoba rounded out the catalogue of surprises, the latter representing a particularly costly error given Racing Cordoba's historical pedigree in the division.
Despite the 1X2 struggles, the supplementary markets offered considerably more satisfaction. The 72% accuracy on Over/Under selections indicates solid reading of goal-scoring patterns across the fixture list, with many matches falling into expected parameters. The 61% success rate on Both Teams To Score further demonstrates that while predicting outright winners proved elusive, forecasting the general flow and attacking intent of these encounters remained within reach. The data suggests the model may benefit from a recalibrated approach to home advantage weighting in the Primera Nacional, where atmospheric factors and passionate home support frequently overturn the calculations that work elsewhere.
Notable Results from a High-Scoring Fourth Round
The fourth matchday of the Primera Nacional delivered a remarkable success rate for prediction models, with all four featured fixtures resulting in outcomes that aligned with pre-match forecasts. The round was characterized by emphatic victories, including two commanding 3-1 scorelines that showcased attacking intent from the victorious sides.
The standout result of the weekend came at Club Atlético Güemes, where Gimnasia Jujuy secured a convincing 3-1 away victory. Despite the prediction model favouring the away win with only 39% confidence—reflecting the inherent difficulty of forecasting results in a competitive second tier—the visitors justified the selection with a clinical display. Gimnasia Jujuy's triumph by a two-goal margin proved to be the most decisive result of the round and the sole fixture to exceed a one-goal margin.
Almirante Brown and Colegiales both recorded identical 3-1 home victories against Atletico Mitre and Quilmes respectively. Both home wins carried similar probability assessments at 50% and 41%, yet the manner of execution suggested dominant performances from both sides. The convergence of two identical scorelines within the same round highlights a pattern of home-side supremacy during this matchday.
Deportivo Madryn's 2-1 victory over Los Andes completed the round's results, with the home side prevailing in a closer contest. The predicted home win materialised despite Los Andes' competitive showing, resulting in a single-goal difference that keeps the result within expected parameters. Across all four matches, the prediction accuracy demonstrates reliable model calibration for this stage of the season.
Round 4 Reshapes Primera Nacional Landscape
The fourth round of the Primera Nacional 2026/27 campaign delivered a significant shake-up across both zones, with the updated standings revealing a tightly packed upper third of the table. Gimnasia Jujuy surged to the summit of the promotion places with 36 points accumulated through 11 victories, three draws, and four defeats. Their position at the top reflects consistent point-gathering throughout the opening month, though the margin separating them from the chasing pack remains wafer-thin.
Deportivo Moron and Ferro Carril Oeste now sit level on 34 points, meaning just two points separate the top three teams competing for automatic promotion. Atlanta's 33-point haul keeps them firmly in contention, while the gap to Los Andes and Tristan Suarez in third place indicates the promotion race extends beyond the leading quartet. With matches still to be rescheduled due to earlier postponements, the fixture schedule remains compressed, creating additional pressure on teams competing across multiple fronts.
