Best-skilled relievers in August 2025

Here are the best relievers in August by K%-BB%. Remember that we are talking about maybe 9-12 innings, tops, so you will want to check their overall skill sets to see if they are someone who can carry you to the finish line. Here, we include season-long xERA (xERA') as a checkpoint.

This first grouping has the tremendous K%-BB% of at least 35%, which means these relievers had a high strikeout rate, likely a low WHIP and a low xERA. In August, there were only five:

K-BB% 35%+	SV	HD	IP	xERA	WHIP	K%	K-BB%	HR/9	xERA'
Fairbanks, Pete TAM	4	0	10.0	2.40	0.80	43%	43%	3.6	3.74
Chapman, Aroldis BOS LHP	8	0	10.1	1.76	0.10	40%	37%	0.0	2.60
Speier, Gabe SEA LHP	0	5	10.2	2.11	0.38	36%	36%	0.0	2.82
Diaz, Edwin NYM	1	0	8.0	2.04	0.88	38%	35%	2.2	2.28
Leasure, Jordan CHW	2	1	9.2	2.91	0.83	42%	35%	2.0	4.19
