Santiago will pitch out of the bullpen in long relief after manager Rick Renteria announced Carson Fulmer will be the fifth starter, Daryl Van Schouwen of the Chicago Sun-Times reports.
Santiago thrust himself into the competition, allowing just one earned run over 12 spring innings, but in the end, Renteria chose the young prospect instead of the 30-year-old veteran. Despite Fulmer's ugly spring (11.81 ERA, seven HR, 10.2 IP), it's a defensible move. The White Sox are in rebuild mode and can afford to put up with growing pains if it helps Fulmer become a better pitcher in the long run.
