Targeting low xERAs

As always, we focus on skills. This column focuses on just the xERA leaders among relievers to-date (provided sufficient innings) and checks out the rest of the skill set, the roles, and the projections for the balance of the season. There are four groupings that give us nearly 30 relievers to examine, and then a fifth grouping with xERAs to-date over 3.00 but projected xERAs under 3.00 to give us a few more names.

We start at the top with seven relievers who own a xERA under 2.50 to-date. These relievers are the ones with WHIP at or under 1.00, K% over 30%, K%-BB% over 25%, HR/9 under 1.0. In the 30 or so innings so far, they have been the cream of the crop:
