Bringing up prospects is something even teams in the hunt do, especially to deepen their pen.
I'd bring up Dalbec, Chatham, Duran, Ockimey, Centeno and a few pitchers no matter where we are in the standings.
Playing the guys and when (how often) is what is up for debate. I can see holding off totally playing the kids until after these 7 games, but some players may be better choices than what we have, even if winning is the objective.
