Players speed (SX), is taken from a Bill James concept that measures the various elements that compromise a runners speed skills.

1. Stolen base efficiency

2. Stolen base frequency

3. Triples rating

4. Runs scored as a percentage of times on base.

Each one comes with a math equation formula.

Roughly speaking, the likelihood of a hit depends on

(1) the speed of the ball (so that it can elude the fielders),

(2) the distance of the ball (so that it is a long way from 1st base),

(3) the speed of the batter (so he can out run the throw).

The (3) is established by James formula above in SX.

(1) and (2) are established in PX. This is a weighted ratio of doubles, triples, and hrs per ab.
