This short article introduces and studies a modified offensive earned-run average (MOERA) index which is based on a stationary Markov chain and evaluates the contribution of a player in baseball. An original offensive earned-run average (OERA) index does not consider the effect of stealing. The MOERA index proposed here includes the effect. Some examples are presented for Japanese professional baseball players.
