**The 2026 Peru Liga 1 season features tight defensive competition across the 18-team field, with roughly half the matches completed in the aggregate table and no club establishing clear separation in clean sheets.** Alianza Lima leads the overall standings with the league’s stingiest defense (14 goals conceded in 23 matches, or 0.61 per game) and strong goalkeeper contributions from Alejandro Duarte, yet several sides remain clustered in clean-sheet totals. Sport Boys, Deportivo Garcilaso, and Universitario have posted comparable shutout rates in recent form, while promoted sides like Deportivo Moquegua and others have sustained competitive defensive outputs amid the split Apertura-Clausura format. Market pricing reflects this parity, with implied probabilities bunched between roughly 42.5% and 46% because multiple teams retain realistic paths to the highest total depending on remaining fixture difficulty, home/away splits, and potential roster stability. Recent Clausura results show continued balance—low-scoring draws and narrow wins are common—preventing any single side from pulling away. Weather, travel in the Clausura phase, and possible late-season fatigue or injuries further support the narrow spread, as outcomes remain sensitive to small variances in results over the final months.
