Severino was done after the 4th inning. Everyone who know the Yankees well could see it. One of Boone’s shortcomings, IMO, is leaving pitchers in the game too long when it is clear that they are done. The real hero last night was Betances who entered the game with 2 base runners, and dominated for 2 innings. Ideally, Severino would be a really good middle reliever, set up guy, or closer. He’s not the guy who’s going to consistently give you 6-7 innings.
