I don't think Soriano's willingness to change positions is pushing anyone out of the starting lineup. As it stands, Soriano is the CF (Pie is a substitute at this point), Murton is the RF, and there is a rotation in LF. The example you gave is a little different because Aramis is the established third baseman. Besides, let's keep in mind that Soriano was merely answering the question about, possibly, moving from CF if Pie stays with the ML team. I think his answer was more about doing whatever is best for the team/what Lou suggests. That is exactly what his answer was, I don't know how anyone could infer something else.
