What happened: Didier Fuentes ranks 11th in relief ERA and 17th in strikeout rate. His relief work has generated 1.8 fWAR, the 10th-highest total in MLB.
Why it matters: Fuentes sits among MLB’s top 17 relievers in run prevention, strikeout rate and accumulated value. That three-category profile strengthens the case for a significant October role.
By the numbers: Fuentes' three listed MLB ranks are 11th in ERA, 17th in strikeout rate and 10th in fWAR, an average ranking of 12.7.
What to watch: His late-season workload and performance through September will show whether those relief numbers carry into October.
