Both Grienke and Matt Moore were strong through the first three innings. They both only gave up a hit each over those three frames, and only one walk given up, by Grienke. The strikeouts weren't therpiling up for either pitcher, with Grienke only having two, but they were both getting the job done well.
In the bottom of the fourth, that changed for Moore and the Diamondbacks offense. Paul Goldschmidt continued his resurgance and hit a one out double. He was then sent to third thanks to a single from Beef.
Then things got interesting. Brandon Drury swung at a pitch.
