As you all probably know baseball is not an Olympic sport. It was removed for several reasons:
1. The best players were not involved as they were in professional leagues.
2. Baseball prowess is basically limited to the Northwestern Quadrisphere (is that a word?) and the Pacific Rim.
Baseball though is no different than other sports in the Winter Games. Hockey is ruled by only a few countries. Same is true about curling, biathlon, and even figure skating to a degree. Baseball is just as diverse country-wise as these other games . . . so I think Baseball should be welcomed as a Winter Olympic sport for these reasons:
1. No competition from the Major professional leagues, so the best players will be available.
2. Most winter destinations have domed stadiums available for use or modification that could house a baseball facility. For instance, Vancouver has the BC Place Stadium which was designed as a multi-use stadium to attract a MLB club.
3. It will help diversify the Winter Olympics and bring more countries to the plate, which is good for the sports and good for the IOC making money.
