Dominance is what we seek from our pitchers and it's best identified not by radar guns or movement charts but by the hitters when they swing and miss.
We've done this before more roughly. But thanks to Fangraphs and our friends at Baseball Info Solutions we have more complete data now that addresses some problems when we last addressed swinging strikes, most chiefly, sample size.
So now we're limiting our search to 150 swings and misses. And then we look at fastballs only and see which pitchers deal the most effective heat when measured by the air conditioning that results from empty opponent's swings. Following each chart are some recommendations to attempt to bring fantasy relevance into sharper relief. However, the relevance of players that demonstrate such clear dominance should be clear to us all.
Here's the list shorted by the percentage of at least 150 swings that were swinging strikes (stats through Thursday):
