This is nonsensical. What information are you basing this on? The guy actually pitched well too.
Joe settled down after giving up four runs. At that point the game was effectively over. It's not as difficult once the pressure is off.
He was an emergency pitcher who could also pinch run. He wasn't called on to pinch run because the situation never arose. The situation arose to actually pitch.
Joe vs. good left-handed batters is a mismatch.
Does he still have options? If so, he starts the season in the minors.
