Baseball has more potential as the next big global sport after soccer because it can be played just about anywhere with just a bat and a ball. Kids in the Dominican will make gloves out of milk cartons to play it. Plenty of cricket-playing countries already have athletes with some of the basic skills to succeed in baseball. I don't see any reason why baseball can't spread outside its current reach. But it isn't likely to happen if MLB jealously guards its talent so that the US has the monopoly on games played by the sport's best players. Part of what spread the popularity of professional baseball across this nation was the barnstorming of teams and players when the sport was still young.
