What does this mean?.. "The Florida Marlins has the best farm club in MLB" Details...?

Actually, it is a fact that each major league club has a farm that the players take care of. Florida has an unfair advantage, having the best growing conditions, but they do grow the best tomatoes, among many other things. The farm is always underneath the grandstand in center field. As you could guess, the Minnesota Twins and the Toronto Blues have the worst farm clubs.
