All,
The purpose of the question originally posed was not because I didn’t understand spin rate, as implied above, but was a question as to whether it is the “metric du jour “...and whether it as important a metric as is being made today. I think Fenway’s explanation above is really in line with what I was kind of thinking, and he explained it well. But, and this is a big but, I also think those guys who are locating these pitches would be successful regardless of spin rate, however the spin rate does add an additional benefit. My question, which maybe I didn’t state clearly, was motivated in part by the emphasis on spin rate at the younger ages (high school) where control in general isn’t refined yet for most arms.
This will be my last post for a while...hope you all have a pleasant holiday season, even the dynamic duo of BOF and TPM...
