Most teams that only score 1 run in-game 7s lose. Even if you know the signs you still have to hit the ball. You still have to execute all the other aspects of the game. Pitching, defense, base running, etc. When Koufax and Gibson were pitching in the 60s they often told batters what they were going to throw and dared the opposing batters to hit them. In Koufax’s game 7 win over the twins his curveball was not working and he had to rely on his fastball most of the game. 9 innings On one pitch. The Twins knew it was coming.
