I think there is much more interest in MLB World Wide after this event. People in other countries will watch MLB for their players from the Classic. Great for marketing MLB globally. Plus many players from other countries getting exposure to MLB scouts etc. from this.
I think its very good for the game, I wish the format would have been different ( would last longer ) but it's hard with so much at stake with injuries and regular season so close to have players playing a long tourney.
