I hope to live to see the day a Cuban team is admitted into the MLB.
I was on a mission trip in Havana back in November. We were able to go to a couple of Industrailes (the Yankees of the Cuban league) games.
It was like high A ball. I never saw a pitch over 90 mph and 6 runs was the most scored in either game against suspect pitching. However, the defense was quite good.
I noticed that just like MLB the ball was tossed out of play when the pitch was in the dirt. A couple of pitches later they ran the same balls back to the umpire.
