The Diamondbacks bullpen is faring much worse than many predicted. Only one regular, Brad Ziegler, has an ERA under 3.00. Only two check in at under 4.00. Arizona has demoted one of their best relievers from last year, Evan Marshall, and removed a struggling Addison Reed from the closer's role.
As a whole, the bullpen has a 4.50 ERA, ranking 11th out of the 15 teams in the National League.
Meanwhile in Houston, a Diamondbacks castoff is putting together a career year. Right-hander Will Harris has allowed just one run in 19 innings, pitching mostly at the back end of the bullpen.
