As a teenager, a pitcher should not be allowed to throw two-hundred-inning
seasons or have a BFS (batters faced per start) over 28.5 in any significant
span (150-plus innings). This does not include instructional league or
winter-ball innings if there is a reasonable amount of time off between the
leagues. (MY NOTE: 28.5 BFS is a 100 pitch limit, note that this is the
average and not an absolute limit.)

A teenage pitcher should not start on three days’ rest, which generally
means no four-man rotations in A-ball.

For ages twenty to twenty-two, they should average no more than 105 pitches
per start for the season (105 pitches is roughly equivalent to 30.0 BFS). A
single-game ceiling should be set at 130 pitches.

For age twenty-three to twenty-four, the restraints can be eased up, but
their season average should stay under 110 pitches in most cases. The
single-game ceiling can be jumped up to 140 as long as the pitcher is still
strong.


大致上是說 在25歲以前的投手 不應該超過110球(當然每個年紀有每個的限制)

還有文中也提到了 當你在某天投的特別多後 接下來的一個月內

你的成績會掉落   140~149球會掉落 6%   130~139 2%

然後之後的先發局數會下降  140~149 下降2% 130~139下降1%


等我暑假來把這篇好好翻翻

: :  我覺得大家都在討論投球數的問題~~為啥以100球為限??
: :  這當然就是要保護投手~~剛剛討論到蔡小英已經投了100多球了
: 100球為分界是因為
: 根據統計
: 一
: 先發投超過100球後 生涯會受傷的機率會大增
: 二
: 100球後 大部分的投手球威跟球速都會下降
: 除了避免受傷的原因
