Last season, the Braves led the NL with a 3.74 team ERA. The Cards were at 3.75, the Cubs at 3.81, and everyone else over four. The league ERA was 4.30.
We’re just what, a seventh of the way into this season, so it’s early yet, but seven NL teams have ERAs below four. The Braves are at 2.97, which would be the best in the majors since… Gosh, I don’t know how long. A long time. (UPDATE: The last sub-three ERA was the Dodgers in 1989; there have only been ten since the introduction of the DH in the AL, which was a pitcher’s league in the early seventies.) But that’s nothing compared to the Marlins’ 2.54 team ERA. That would have been the second-best individual ERA in the league last year.
Interestingly, the league ERA hasn’t fallen too much, because the bad pitching staffs are even worse than usual. The Rockies have a 6.37 ERA, which would be the worst in their storied history; even the Rockies have only once topped a 6.00 ERA, a 6.02 in 1999.
It’ll probably all even out in the end (for one thing, the Marlins have to make up games in Colorado and the Braves haven’t played there yet) but I thought it was interesting.
