Since defeating Clayton Kershaw and Madison Bumgarner (both reigning MVP's in their own right), Archie Bradley's season has taken some unfortunate turns. He was hit in the face by a line drive off the bat of Carlos Gonzalez, but was able to return fairly quickly after what looked like a devastating injury. Bradley suffered a sinus fracture and missed three starts, and has been awful since coming back.
His ERA was fantastic before the injury, but his BABIP, FIP, and SIERA suggested that there were worse times ahead; and they were right. His strikeout rate and walk rates are trending in the wrong direction, while all of his other statistics skyrocketed. The results have not been good, and now he appears to be dealing with a shoulder injury.
He'll spend the next two weeks resting his shoulder, and will likely have to make at least one rehab start before coming back to the rotation. Taking his spot will be Robbie Ray, who was acquired by the Diamondbacks in the three team deal with the Tigers and Yankees.
In 41.2 innings this season at AAA with the Reno Aces, Ray posted an ERA of 3.67, and an FIP of 3.10; both of which are fantastic considering he's been pitching in the PCL. He managed a HR/9 of just 0.22, and struck batters out at a rate of 12.31 per nine innings. Ray has earned this spot in the rotation, and will hold on to it until Bradley comes back, or proves he's not ready for full-time starting duty.
