Why so many LH soft-tossers

By Tangotiger, 12:15 PM

Ben gives us the data:

........ Righty Lefty
Starter  91.2 89.4
Reliever  92.1 89.8

Good stuff Ben.

Can you give us the following breakdown:
- Start with a count of the number of RH starting pitchers (say that’s 100).
- Take the fastest 10 LH starting pitchers (or one-tenth the RH count)

What is the fastball speed of these two groups? Will it be similar?

Basically, we want to keep the proportion of pitchers equivalent to the proportion in the real-world. The extra LH pitchers are all those who are the softer tossers and are bringing down the overall average.

***

Not exactly all this as fastball speed is not the sole determinant. In any case, if you show a breakdown like this, you might get something that is more illustrative.
