Huh? Pretty sure that the experts who count know that Romero was short arming with a sore elbow. Then he had surgery and tried to regain form with proper mechanics, something he never really had, in order to keep his elbow healthy. He found that pitching in pain or pitching unlike himself netted the same results-- no command!
Now he's trying to just pitch the way he used to and it'll probably work until two years from now when his UCL is torn up.
Btw, Yogi was joking.
