“Yesterday's home runs don't win today's games”
The earliest quotes similar to this are presented as unattributed folk wisdom, such as this example from 1959:
As Brother Allen of Newsweek indicated, it has been fun, but don't try to rest on your laurels. Always remember, “YESTERDAY’S HOME-RUN DOESN’T COUNT IN TODAY’S GAME,” and today’s game is well under way.
The quote does not begin to be attributed to Babe Ruth until the 1980s, nearly 30 years after its first appearance.

“1. You can't win. 2. You can't break even. 3. You can't even get out of the game.”
Several publications attribute the quote to Ginsberg, probably the first one is The Coevolution Quarterly in 1975 [Google books https://books.google.it/books?id=MylJAQAAIAAJ&q=%22ginsberg%27s+theorem%22&dq=%22ginsberg%27s+theorem%22&hl=en&sa=X&redir_esc=y], but there's is no evidence whatsoever that he ever pronounced it.
