Ruth, Babe; Considine, Bob (1948). The Babe Ruth Story. E.P. Dutton & Company: New York. p. 130. Retrieved 2018-07-06. "Lou stayed with us only a few weeks in 1923. I watched him at batting practice, and after seeing him clout a couple into the bleachers, I said to someone standing near, 'That kid sure can bust em.'
