Ennder, You obviously haven't been paying attention to what's been happening late last season and in spring training. Peralta hasn't had control problems lately. In 15.2 IP this spring he has only given up 4 BB. Even in the Majors in his starts last season he showed good control and ability to limit the damage by pitching 6-8IP in 3 of his 5 starts, and really only having 1 bad start out of 5. Fiers has given up 8 BB and 29 Hits in 19IP and has obviously been off, and RR has stated publicly that Fiers isn't hitting his spots and locating, which Fiers HAS to do to be effective, because he can't hit 98 MPH like Peralta can to get out of trouble. By the way, Fiers has had the worst spring when you compare him to Peralta. His last 2 starts have been terrible. If Fiers has another bad start I believe it's pretty obvious that he will be sent to AAA Nashville to work on things. That's just how much he is off his game right now.
