**Multiple Peruvian Liga 1 sides maintain closely matched clean-sheet totals through the ongoing 2026 aggregate campaign, leaving the market for the team with the most shutouts unusually wide open.** Alianza Lima leads the table with the stingiest defense overall (20 goals conceded in 29 matches), supported by goalkeeper Alejandro Duarte’s strong run, while Sport Boys, Deportivo Garcilaso, and Atlético Grau feature keepers (Diego Melián, Patrick Zubczuk, Patricio Álvarez) posting double-digit clean sheets in recent tallies. Teams such as Universitario, FBC Melgar, Sporting Cristal, and others sit within a narrow band of results, aided by comparable defensive organization, home/away splits, and fixture congestion in the Clausura phase. With roughly one-third of the schedule remaining plus playoff implications, small shifts in form, injuries, or results can reorder the leaderboard, which explains why traders assign nearly identical implied probabilities across the field rather than consolidating behind any single favorite.
