Speed of the infielders - If the infielder in front of the outfielder has great speed, and
can go back extremely well on a fly ball, this will enable the outfielder to position himself a
few steps deeper. Likewise, if the infielder in front of the outfielder has poor speed, and
has proven that he has a difficult time going back on fly balls, the outfielder would have to
position himself a few steps shallower.
Pitcher's ability - If the pitcher on the mound is a power pitcher with an excellent fast
ball, it will usually cause batters to hit the ball late. If he is a breaking ball pitcher with
very little velocity on his fast ball, the tendency would be for most hitters to pull his pitcher.
If a pitcher is wild, it is best to shade all hitters a little deeper, especially if the pitcher is
wild high. If a pitcher is tiring late in a game, it is best that the outfielders shade a little
deeper.
Runners on base - Before each pitch, the outfielders must know how may men are on
base, where they are, how fast they are, and what effect will be on the status of the game if
they score. The batter-runner would also be considered as a baserunner. This information
would better allow the outfielder to make the proper throw, anticipate steals, pick-off plays
and bunts.
