to go straight and fast and not sink. But in Coors Field, this resistance is
weakened. The fastball sinks more than usual while it also resists the
sinking because the speed is faster.^18
These two contradictory effects make problems on the pitcher's
mechanism. Pitchers throwing fastballs with high rotation speed might
not pass the strike zone and break, and pitchers throwing fastballs with
ordinary rotation speed might become faster and throw higher than
usual. To say, fastballs of a pitcher differ massively based on the balance
between the ball speed and rotation speed. Plus, the fastball is the main
and primary ball for almost all of the pitchers. Pitchers throw fastball
with a risk of getting hit, because it is relatively easiest to control, being
the key ball to lead the ball count to work out the game. In Coors Field, a
ball will be thrown in unintended places when a pitcher throws a ball as
usual, therefore disturbing the balance and control of a pitcher as a
whole.^18
