Grayson Rodriguez allowed five runs on six hits in four innings in a loss to the Red Sox on Monday.

Rodriguez threw just 61 percent of his pitches for strikes in this one with a 23 percent CSW. His changeup posted just a 50 percent strike rate, and that has been one of his best pitches this season. On a positive note, he did post a 15 percent swinging strike rate on his curveball, and he has struggled for most of the season to get whiffs on his breaking balls. Rodriguez will take a 6.28 ERA into a start against the Nationals on Sunday, and wejust can’t recommended using him in that game.
