RELIEVERS: Current and Projected K%-BB% Leaders

This week, we examine two lists. The first list contains relievers with a K%-BB% at or above 30% here in the early going with at least 12 innings pitched. The second list contained relievers projected to have a K%-BB% at or above 25% and at least 40 more innings projected. Applying the filter criteria, here is the first list that pops up--and it is a great list:
