"Vinny enjoyed his time here," Bochy said. "Vinny could see something [was] happening through the media, the talk about trying to get more production out of third base. He's been through it before at Tampa [in 2001]. He came out of that and put together a few good years."
Bochy broke the news to Castilla after Tuesday night's game. Castilla is expected to clear waivers on Friday, at which time he becomes a complete free agent.
"It doesn't get more difficult than that [breaking the news], the respect you have for Vinny, who he has, the career he's had," Bochy said. "It's been a pleasure and an honor to manage him."
