The San Francisco Giants have received permission from the Padres to interview San Diego manager Bob Melvin for their open managerial job, a person with direct knowledge of the decision said Sunday. When the Giants inquired about Melvin, the manager expressed interest in going through the process, the person said, speaking on condition of anonymity because the Giants' managerial candidates aren't being made public. The Athletic first reported Melvin was in the mix with San Francisco.
