One-day international cricket matches face the problem of weather inter-
ruption. In such circumstances, a so-called rain rule is used to decide the
outcome. A variety of approaches for constructing such rules has been pro-
posed, with the Duckworth-Lewis method being preferred in the sport. There
are a number of issues to consider in reasoning about the e
↵
ectiveness of a
rain rule, notably accuracy (does the rule make the right decision?) and
fairness (are both teams treated equally?). We develop an approach that is
a hybrid of resource-based and so-called probability-preserving approaches
and provide empirical evidence that this hybrid method is superior in terms
of fairness while competitive in terms of accuracy.
