Part of the Yankees’ recent focus on using tech resources to get their pitchers to improve — the “Gas Station” in the Tampa complex, for example — is centered around taking advantage on concepts that have been around for quite some time, but have gradually become more important with each passing year. Two of those concepts are spin efficiency and spin axis.
Sometimes, fans pay too much attention to raw spin rate, as if it was the only thing behind the “rescue” or “revival” of a pitcher. But truth be told, that’s not necessarily the case because the efficiency of that spin rate is much more important.
