**Sport Boys leads the Liga 1 clean-sheet race with 12 through 28 matches, narrowly ahead of Alianza Lima and Deportivo Garcilaso on 11 apiece, while Atlético Grau sits on 10 and several others trail at 8 or fewer.** This tight bunching stems from comparable defensive organization across contenders, with Sport Boys posting the highest clean-sheet rate (around 43%) driven by strong home results and goalkeeper Diego Melián’s consistency. Alianza Lima’s league-best goals-against tally (19) and Garcilaso’s balanced splits keep them in range, while varying home/away form, remaining Clausura fixtures, and potential late-season momentum shifts sustain the even trader consensus reflected in the bunched probabilities.
