RELIEVERS: At or below 0.5 HR/9

This week, the column focuses in on relievers with a HR/9 at or under 0.5. Why? Because the relievers with at least ten innings and a 0.5 or better HR/9 average 1.171 runs better in actual ERA than in xERA so far in 2021. If we filter these "home run stingy" RPs for simple 100 BPV, we now have a nice set of relievers to discuss.

Let's start with the closers and quasi-closers on this list (100 or better BPV and 0.5 or lower HR/9):
