I was expecting to see Yo transition into an elite pitcher this year. He has shown flashes, but even earlier in the season when he was pitching better, high pitch counts prevented him from going late into games (which I believe an elite pitcher should do). I do wonder if the pressure of needing to be the "ace" of the staff has gotten to him over the course of the year. He is still a young guy, and having everybody counting on you to go 7-8 strong innings everytime out to save the bullpen could have an effect on a guy. with that said, if he is truly healthy, I see no point in shutting him down this year. Every pitcher/player goes through slumps during the season and needs to learn to work through it.
