The San Francisco Giants hope to begin interviewing internal managerial candidates this week as they seek to replace Gabe Kapler, who was fired last Friday with three games left in a second straight losing season. President of Baseball Operations Farhan Zaidi said discussions are underway about who the club would like to speak with from inside the organization initially, probably a couple of people — and Zaidi is relying on input from retired catcher Buster Posey, who's now part of the ownership group. Zaidi also noted he hopes to begin reaching out to other franchises early next week to receive permission to interview people on those staffs.
