On October 8, 1967 — Boston’s Ken Brett becomes the youngest player ever to pitch in the World Series when he appears in relief against the Cardinals in Game 4 of the Fall Classic. The 19 year-old Red Sox rookie southpaw, the older brother of future Hall of Fame third baseman George Brett, tosses a scoreless eighth inning, yielding a walk in the team’s 6-0 loss at Busch Stadium.
