Did Yogi Berra really say all those things he said?

Berra, who died at 90 late on Tuesday, was one of baseball’s most famous figures, known as much for his memorable quips as for his excellence on the field. But the origin of many of these so-called Yogi-isms is murky — and some he never said at all.

Berra playfully acknowledged the twisted attribution over the decades, characteristically revealing nothing and everything in his responses. (“I might have said ’em, but you never know,” he once said.) In 1998, he published an aptly titled book on the matter, “The Yogi Book: I Really Didn’t Say Everything I Said!”

Here is an effort to untangle the beginnings of his most famous remarks:

“It ain’t over till it’s over.”

By most accounts, Berra said this about the 1973 pennant race. Berra was managing the Mets, who were in fifth place at the end of August but rallied to win the National League East.

Berra did say, “You’re not out until you’re out,” according to Dave Anderson, who quoted Berra in a New York Times column when Berra was managing the Mets in 1974.
