In his first season with the Arizona Diamondbacks, in 2016, Zack Greinke wasn't especially good. Last season, he was quite good.
This spring, Greinke is lurching back toward "not good," and that's decidedly bad news for the Snakes.
It might even be a disaster.
Through 1.2 exhibition innings, Greinke sports a 5.40 ERA and a .375 opponents' batting average. More troublingly, his fastball has been sitting in the mid-80s and topping out at 87 mph, per Nick Piecoro of AZcentral.
In his most recent outing on Wednesday, he exited after an inning with groin tightness, per ESPN.
