Though it's not the ideal situation to ease phenom Mark Prior (above) into their rotation, the reeling Cubs, who were 14-27 through Sunday, had no choice but to call him up. Chicago fans have been eagerly awaiting the arrival of the 21-year-old righthander (5-2, 2.29 ERA in the minors), who was scheduled to make his big league debut on Wednesday. "The one thing I've been trying to avoid is making this kid the savior," said Cubs G.M. Andy MacPhail. "If he's got to be the white knight who rides in, we're really asking a lot."
