Welsh baseball?

I don't know a thing about the game called "baseball" in Wales. All I know is it's not the same game I refer to by that word. According to one web site I found:

Welsh Baseball is an 11-a-side team game played with a wooden bat and a hard ball, mainly in South Wales and parts of north-west England. It differs in several respects, and notably in the matter of equipment, from the more widely-known form of baseball played in the USA. The clothing worn by the players is much simpler and catching gloves and other protective gear is not used. The bat is made of willow and has a flat striking edge which tapers evenly into the handle.

The governing body appears to be the Welsh Baseball Union, based in Newport. The local Member of Parliament, Paul Flynn, writes of his home region:

Even in sport, Grangetown and other working class parts of Cardiff had its own distinctive personality. Only areas of Newport and Liverpool share our devotion to Welsh Baseball. Crowds of up to ten thousand would flock to important matches in parks in Roath and Grangetown. Not only was it the most popular summer sport in the war, it was the only one. Cricket was in hibernation. Few Cardiffians of my age saw a game of cricket before their tenth birthdays.

SABR UK considers the historical relationship between the two variations of the bat-and-ball game.
