John Miller, a pitcher for the Orioles in the mid-1960s, passed away on June 5, 2020 at age 79.
Miller pitched for the Birds from mid-1965 through the end of the 1966 season, although he didn't play in the '66 World Series. (With 3 complete game shutouts in their 4-game sweep, the O's only needed 4 pitchers.)
He was the Orioles' 5th starter in 1966, but when the first four are named McNally, Palmer, Bunker, and Barber, there's not much for you to do.
He also played a few games in the '62, '63, and '67 seasons. Miller retired after playing the 1968 season in single-A ball.
