...first of, it was also only a "10% tear" and so the decision not to have the surgery was based on the very best Doctors advising the Yanx not to have it done....Tanaka's stuff is the same as before but his command and location are what hurting him..that's not physical. ...The Yanx also took the advice from the Doctors because there's always a chance that the surgery and recovery does not work as intended and the pitcher never returns to form...you just never know. ...Pineda has been just as inconsistent and his problem is not physical either. ...that fact is, none of us knows for sure what the situation is.
