Soriano will begin pitching at Double-A Tennessee in the near future, Gordon Wittenmyer of the Chicago Sun-Times reports. Soriano, who signed with the Cubs nearly a month ago, has been working out at the team's facility in Arizona, and he'll now report to Tennessee to begin pitching in minor league games. The hope is that he'll throw well enough to potentially work his way up to the big leagues after the All-Star break.
