Pirates manager Clint Hurdle said Wednesday that he wants to continue getting Josh Harrison regular playing time when Neil Walker (appendectomy) returns next week. Harrison is batting .280/.353/.452 with 11 home runs and 35 RBI in 62 games this season. "He's added an edge for us at the plate, in the field, on the bases," Hurdle said. "His enthusiasm and energy, I do think, drips onto the other guys as well." But it's hard to figure how he will remain a starter given the setup of the Bucs' depth chart when Walker returns to second base.
