he center fielder can scoop up a
ball hit deep into center field
and throw it more than 200 feet to get a
runner out at second base.
Throwing that far is no accident —
it's math and physics!
The force of the throw gives a ball
forward motion. But as the ball
travels, gravity pulls it downward.
(Gravity is such a downer!)
So, the ball must be thrown
upwards and outwards at an
angle so that it can travel the
farthest before gravity pulls
it to the ground.
This number
gives you an idea
of how well a
batter hits. To
figure out a per-
son's batting
average, divide
the number of
hits by the
number of
"at bats."
This math
formula is used
to find out how
many runs a
pitcher allows in
nine innings of
pitching. Pitchers
want to keep
this number as
low as possible.
Josh hits the ball half of the time he is at bat,
so he has a .500 batting average.
That fraction can be reduced to
Josh hit the ball 3 times in 6 at bats. Sean allowed 7 runs in 34 innings pitched.
You can write it as a fraction:

Sean has an ERA of 1.85, which means he
allows under 2 runs every 9 innings.
Divide that number by the number
of innings pitched:
To calculate his ERA, multiply the
number of earned runs X 9
