"A manager uses a relief pitcher like a six shooter, he fires until it's empty then takes the gun and throws it at the villain"

In this quote, Dan Quisenberry compares a supervisor's use of a relief pitcher to that of a six shooter. Just like a six shooter, a manager will continuously use their relief pitcher up until they are no longer efficient, similar to shooting bullets up until the gun is empty. Nevertheless, once the relief pitcher is no longer beneficial, the manager will discard them and proceed to the next option, just like tossing the weapon at the bad guy. This contrast highlights the tactical and in some cases callous nature of handling a baseball team, where the ultimate objective is to win at all expenses.
