Deivi Cruz is a very similar player to Pat Meares. According to baseball-reference.com, when compared to Cruz, Meares' similarity score is 918.
Meares also has a similarity score that's very close to another National: Cristian Guzman. This is interesting, because in 1999 the Pirates signed a contract with Meares that was just as outrageous as the contract the Nationals signed with Guzman, and the Meares contract was one of the reasons the Pirates fired GM Cam Bonifay. In other words, Jim Bowden didn't learn anything from the Pirates' blunder. Given the similarity of the three players, can a ludicrous long-term contract with Cruz be far away?
