Keith Couch is one of the more intriguing Red Sox pitching prospects right now, and is currently pitching for the high A Salem Red Sox. Last year he went 7-5 with a 3.54 ERA, a 1.19 WHIP, and 123 strikeouts in 137.1 IP for the Greenville Drive.
This year, he’s 4-3 with a 3.52 ERA, a 1.52 WHIP, and 43 strikeouts in 46 inning for the Salem Red Sox. His FIP is 3.11, which is very impressive and suggests that he’s been better than his ERA suggests.
He throws a 90-93 MPH sinker, a 77 MPH curveball, and a low 80s changeup that still need work. He’s most likely suited for the bullpen, but it’s too early to say for sure. He’s one of the more underrated Red Sox prospects right now, and hopefully he gets talked about more going forward.
