What dialectical past tense form of the word “slide” did Dizzy Dean usually use (his contribution to the vocabulary of baseball)?

Pitcher and announcer Dizzy Dean coined many new words and phrases to describe the game of baseball. He said players “slud” into base, and when they went back to their previous base they returned to their “respectable bases.” After being hit in the head with a ball in the 1934 World Series, he said, “the doctors X-rayed my head and found nothing.” According to Paul Dickson’s Baseball Dictionary, during a broadcast of the “Game of the Week” Dean referred to an act of courage as “testicle fortitude.”
