Relief pitching has reached a tipping point.
For half a century, ever since the mound was lowered in 1969, relief pitchers posted a lower ERA than starting pitchers. That no longer is true.
As managers go to bullpens earlier and earlier, and as the use of openers grows, workload is catching up to bullpens.
Relievers have a higher ERA (4.50) than starters (4.44) for the first time since 1969. Only three years ago, relievers’ ERA was almost half a run better than that of starters (3.93 to 4.34).
Bullpen ERA this year is the second worst in the past 69 years (only 2000 was worse) and the eighth worst of all time.
