EDGE Analysis

It's been a disappointing season for the 24-year-old, whose ERA sits at 4.67 through 24 starts after he received a fair bit of buzz as a potential breakout candidate prior to the start of the season. He'll lose his place after failing to throw more than four innings in three of his last five starts, posting a 1.88 WHIP over that stretch.
