Miller allowed three runs on two hits and a walk while retiring only a single batter in relief during Friday's 7-6 win over the Nationals.
Miller was tasked with the bottom of the ninth inning in a non-save situation with the Cubs up 7-3. However, things quickly went awry for the righty, and Chicago eventually turned to Drew Smyly and then Keegan Thompson to record the last two outs of the frame, with the latter picking up the save. Miller saw his ERA climb from 1.64 to 2.17 in the process. His previous success suggests he'll bounce back quickly from the rough outing, as this was the first time he allowed a run since late July, breaking a streak of 11 straight scoreless appearances.
