On Wednesday night in Atlanta, Kyle Nelson and Kevin Ginkel entered a cauldron in the eighth and ninth innings, two unheralded relievers combining to silence a potent Atlanta Braves offense. Less than 24 hours later, Miguel Castro — a trusted high-leverage arm all year — blew up in a similar spot, costing the Arizona Diamondbacks a sweep when he served up a three-run home run to Austin Riley.
This, right now, is the state of the Diamondbacks bullpen. As a whole, it is no longer an abjectly bad unit, like it was last year.
