RELIEVERS: Best skill sets in April 2023

This column examines the relievers who had April's best skill sets and only looks at April's stats. The filter criteria is that the reliever first must have at least one save or one hold, at least seven innings pitched, and at least 20% K%-BB%. Let's start with the cream of the crop: K%-BB% of at least 30% across the month--and--a projected K%-BB% of at least 20%, which means the elite skills are expected to remain sustainable to some degree. This elite list has eight names:

30%+ K%-BB%/proj 20%+   Sv  IP  xERA WHIP  K% K%-BB% HR/9 pSv pxERA pWHIP pK% pK%-BB% p$
