The Diamondbacks opened a short, two-game series against the Royals in Kansas City by sending the team’s ace, Robbie Ray up against their former farmhand, Brad Keller. Keller started out looking strong. He struck out the first batter of the game, Brandon Marsh, on his way to a perfect first inning. He allowed two seeing-eye singles in the second. Then, in the third inning, he pitched another perfect frame, including two more strikeouts (one of them being Marsh - again). But then, the cracks started to show in the fourth inning. David Peralta led the frame off with a double.
