The following is a passage from Bill Pennington's book, “Billy Martin: Baseball's Flawed Genius,” which I'm thoroughly enjoying. It's indicative of just how much we don't see during a baseball game; and how much some people do see:

The Dodgers manager was Billy's mentor from the 1949 Oakland Oaks, Charlie Dressen, who had taught Billy many of his sign-stealing secrets. In the top of the fifth inning [of Game 4 of the 1952 World Series], with the Yankees ahead 1–0, the Dodgers had runners at second and third with one out and pitcher Joe Black at the plate.

Dressen, as he had been in Oakland, was also the Dodgers' third-base coach. From his position at second base, Billy watched closely as Dressen flashed a flurry of signals at Black. Dressen's tempo and movements in the coach's box quickened, which Dressen—watching opposing managers—had always said was a tip-off that some kind of play was on. Sizing up the situation, Billy suspected a suicide squeeze and got Yogi Berra's attention behind the plate. He made a fist, turned his hand upside down, and waved it slightly—the sign for a pitchout. Berra crouched and made the same signal to Yankees pitcher Allie Reynolds.

The pitch was appropriately wide of the plate, and Black could not reach it with his bat as he attempted to bunt. Berra then easily tagged out the Dodgers' Andy Pafko, who had dashed toward home plate on the pitch. The suicide squeeze had failed. The Dodgers never scored in the game, losing 2–0.

“Tell me another player who would have seen that?” Stengel asked reporters afterward. “That's why he's my winner.”

Stengel and his winner, with a couple of schmoes in the background.
