I think I'd prefer them to give the ball to a pitcher, the old-fashioned way, and ask him to give them as many innings as possible. (Hopefully at least five or six.) Reid-Foley. Gsellman. Yamamoto. Szapucki. Even Lucchesi. Whoever. This "opener" thing they've been doing pretty much means you're likely to use five pitchers, and the way things currently are, they can't keep doing that day after day.
