Hey, encountered this tonight and found it odd. Unless I'm mistaken, once a pitcher is brought into a game, he must face one batter, regardless of what the situation of his appearance is. In this case, Eckersley got hurt. A reliever was summoned, and a pinch hitter appropriate to the pitcher brought in, when another pitcher was summoned.

Grant should have faced Concepcion. I'm not worried about this as a "I got cheated" thing, but I don't think Grant gets a pass just because Eck was hurt; he still has to face a batter. So what happened? Why was he allowed to be pulled? Generally this doesn't happen.
