In the midst of a four-game skid, the Chicago White Sox are turning to their pipeline to reinforce their bullpen. The White Sox have called up pitchers Hagen Smith and Tanner McDougal, the team announced on Saturday. On Friday, starter Noah Schultz did not last an inning as the White Sox blundered with two mound visits in the same inning. Even though the White Sox acquired Luis Castillo in a trade, they need some bullpen help. What we don't know:In bringing up Smith and McDougal, the White Sox will have to make a corresponding move and send two players down.
