Start the MLB belt with Atlanta Braves’ win on April 7, 1969 and it takes a different path for 40 reigns: on April 7, 1971 the new line and the original line land in the same hands, and from that day on they never differ again. Every reign since is the same reign on both belts, so this page is the era's record book rather than a second history.
