Relievers above the 20+% K-BB% threshold
Aug 9 2026
A week into August we are distilling down to the 20 relievers who have 1) at least a 20% K%-BB% to-date, 2) no more than a 1.1 HR/9 to-date, and 3) a projected 20% K%-BB% or more for the balance of the season. There are only 20 and not surprisingly, 13 of them are closers. Six of the seven remaining relievers in set-up are left-handed. These are your elite skills arms to bet on for ERA/WHIP in the stretch run. Anything can happen in just 15 or so innings, but these are the best bets and most of them will get you saves.
Let's start with the very top of the chart--the five best relievers in baseball:
| 27+% K%-BB% | SV | SV' | IP | ERA | xERA | WHIP | K% | K-BB% | HR/9 |
|---|---|---|---|---|---|---|---|---|---|
| Miller, Mason SD | 28 | 10 | 47.1 | 0.76 | 1.79 | 0.80 | 49% | 40% | 0.0 |
| Duran, Jhoan PHI | 25 | 11 | 38.1 | 1.88 | 1.85 | 0.99 | 37% | 33% | 0.2 |
| Munoz,... |
