Two points I'd like to make.
#1
If you feel these games are meaningless and that the players involved would be better suited in their respective ST camps, then you aren't a fan of baseball, you are just a fan of your team. Which is fine, but it is a shame because as a baseball fan I can tell you are missing out on some fantastic baseball. Nothing about the atmosphere of the games, both on the field and in the stands, suggests this is meaningless. This is the first time all the best professional players from each country have played together when they were at the peak of their game. It's ground breaking, and it is as exciting as hell.

If a player who you usually root against just so happens to be playing for your country, and he does something big to win the game, what is served taking shots at him afterwards? Seems very sophomoric to me.
