While using Wright himself as a pinch runner might not have been the best move, using a non- pitching starting pitcher as a pinch runner is something that happens all the time in NL games (or NL Parks for interleague games, like the one Wright was injured in.)
The story goes Wright asked to pinch run and really wanted to, so Farrell let him. But if Farrellwanted to use a SP, Drew Pomeranz was available that day and had been a pinch runner earlier that year with the Padres.
But all of this is irrelevant considering Wright’s issue right now is micro fractures in his knee and not the shoulder he hurt on the bases. But if he’s never the same again because of his knee, his downward spiral will still be attributed to Farrell and the pinch running. Like how Matt Clement’s downfall is always attributed to taking a line drive off the head when the real culprit was a severely damaged rotator cuff that he insisted on pitching through...
