The San Francisco Giants have narrowed their search for a new manager to three finalists, a person with direct knowledge of the process said. Former Phillies manager Gape Kapler, Astros bench coach Joe Espada and Rays bench coach Matt Quatraro are the final three vying to replace Bruce Bochy, the person said Wednesday, speaking on condition of anonymity because the candidates' names haven't been made public. Giants President of Baseball Operations Farhan Zaidi is taking his time making the hire.
