Yeah, it stinks that Cesar has to try to get by on only $6.25 million.
That seems to be what the market - a relatively free market (as compared to the structural constraints that impact the majority of MLB salaries) - thinks he's worth.
Yeah, Cesar may be about a 2-WAR player. But he's a mediocre second baseman, who can't effectively play on the left side of the diamond, or in the outfield. What is a 2-WAR player who is limited to 2B really worth? It may be that $6 million is about a market-clearing price for such a player.
