An observation with high leverage will have a large residual (usually an outlier).

Question

Quizplus · Accepted Answer

High leverage points are observations with extreme predictor (X) values, and they have the potential to exert a disproportionate influence on the model's fit. However, having high leverage does not necessarily mean that the observation will have a large residual or be an outlier in the response (Y) variable. Large residuals are indicative of outliers in the response variable, which are not always associated with high leverage points.
