Playing in the Cape Cod doesn't mean that he is coming back, but it would make sense. He could be a early round pick next year.
Whatever the issue was, it caused Rogers and the Cards to lose focus and consequently the game, so the advantage went to CSF. Who knows this could have gone back to the earlier game in the season when Josh lost his first game.
Stealing signs is frowned upon but teams and players still do it. Some guys don't want to know what the upcoming pitch is. If you're caught don't complain if someone on your team gets a fastball in the earhole. Stealing signs is overrated.
