Re: [問題]如果球探簽到假貨...
※ 引述《w1379 (鄉民嘴砲比幹砲厲害)》之銘言：
: 小球員有什麼不良影響？打木棒就不能正確的揮棒？打木棒就人人鳥碰？但很抱歉，
: 要論鳥碰安打的機率彈性好的鋁棒反而機率高，有時後隨便破壞球只要打到球心一樣
: 飛的老遠，長打成績上當然好。台灣目前的貧打現況到底是那群打鋁棒的球員造成的，
: 還是這群打木棒年輕球員造成的，相信各位都有答案。

... I believe, and I have nothing but intuition to back this up, that
people who throw sliders lose their velocity more quickly than people
who don't. As they get older, and their fastball slows down, they tend
to rely more on the slider. The slider takes away from their velocity.
And before too long, their velocity--and the sharp slider along with
it--is gone. Instead of following the natural way to put force on the
ball, they try to create additional rotation by using their wrist. I've
seen this happen many times.

Foreword: The Vanishing Fastball (by Eugene Coleman)
Why, when pitching is so important, is there a shortage of power pitchers?
Velocity has decreased in baseball, to some extent, because young pitchers
don't throw enough fastballs, pitches per workout, or pitches per week. Some
professional scouts believe the problem begins in Little League. Young
players realize that it's easier to trick hitters than to throw a fastball
by them. The end result is a growing number of youngsters with good breaking
balls and below-average velocity.
The trend for high school and college pitchers is similar: College
pithcers today often throw 50 percent off-speed pitches, and the percentage
is even higher in high school. I've charted several successful high school
teams whose pitchers threw 60-65 percent off-speed pitchers.
Many people in professional baseball point to aluminum bats as the source
for changes in basic pitching patterns. The inside fastball, which almost
always jams hitters using wooden bats, loses its effectiveness against an
aluminum bat. Instead of throwing inside, then, pitchers spot their fastball
and use their breaking ball as their out pitch. These young pitchers
basically discard the fastball and do little to develop the strength and
durability of their arms. ...
