Well that's a big sticky question. There are a lot of aspects to this but I think the biggest sticking point still is that when Castro rose to power there were American businesses and citizens in Cuba. Their property was seized and never given back. In total this was a massive amount of money stolen from the U.S. Another way of looking at it is that it has become a 50-year pissing contest between Castro and the U.S. This probably won't change until Castro dies.
Whether or not you agree with it, the U.S. has stood firm in not allowing Cuba to benefit from the U.S. economy. The MLB wants to make it out like this is just about baseball but just like everything else it's really about the money.
Maine has a good swing for a pitcher but on anything that moves, he has no chance. And if it's a fastball, it has to be up in the zone. Basically, the pitcher has to hit his bat. - Mike Pelfrey
