Johan Cruyff, yeah I've heard of him. Before my time (soccer wise, anyway), but I know he was one of the greats. Hadn't realized he was once a catcher too - before he played soccer.
Baseball in Holland goes back to WWII, when Dutch kids took it up in defiance of the Nazi occupiers. There are a couple of major leaguers from Holland and a few others from the Dutch Antilles, where baseball is very popular. Curaçao has become one of the powerhouses of Little League baseball.
