It's not like it really matters, but this doesn't make much sense. Covey faced 10 batters, 1 of whom he intentionally walked and another who reached on error. Of the other 8, he got 4 out. What about that run changes your mind about having him in the pen vs Jose Ruiz, who hasn't pitched since the end of ST?
Again, this really isn't important, but I'm very confused about what kind of decisionmaking process leads to this move.
