QOD;
Seems every pitcher has their own internal clock for length of time dedicated for warm-ups before a game, and before an inning.
Some just need a few throws, some 20 minutes, some up to 40 with a break thrown in the middle
Same with warm-ups before an inning begins. Some need a good 10 pitches to warm-up again, and others can just go w/ 1 throw as a courtesy for the catcher to throw to 2.
In your opinion, what is a good length of time required for warming up pitchers?
