Back in 1929, a ballclub made up of Army soldiers, representing the Fort Sam Houston army base in San Antonio, TX was playing an exhibition game against the MLB team Chicago Red Sox.
On the mound was a 19-year-old Army soldier named Jay Dean. He was apparently pitching quite well and frustrating the professional ballplayers as he kept getting them out.
Finally, in exasperation, one of the White Sox managers shouted from the dugout for his players to "knock that dizzy kid out of the box" and proceeded to call him that "dizzy kid" for the remainder of the game.
Somehow the impromptu moniker stuck and that kid became known as Dizzy Dean for the rest of his life.
I was hoping for a better story, but there you go.
Didn’t he say, it ain’t braggin if you can do it.
There’s a story, perhaps apocryphal, about Dean announcing a ball game. The camera focused on a couple in the stands kissing. Dean supposedly said, “He’s kissing her on the strikes and she’s kissing him on the balls!”
One of my great baseball memories was watching Dizzy Dean pitch an inning in an old timers game in the summer of 1966 in the Astrodome. Other pitchers in the game lobbed easy pitches to the elder hitters but Ol’ Diz’ in his yellowed Cardinals uniform threw good stuff and got all three hitters that faced him out.
I recall that there were other great names in that game but the only two I am sure about were Dizzy and Mickey Mantle, who jacked one over the left field fence.
