"It's a decision we had to make early because Melky would have to start rehabbing, and we have decided to develop our roster," Bochy said before Thursday's game against the D-backs. "Our group of players have done a terrific job."
After receiving a 50-game ban for testing positive for testosterone Aug. 15, Cabrera is eligible to return to the Giants if their postseason extends beyond five games, having started to serve the suspension with 45 games remaining in the regular season. In addition, Cabrera would have been allowed to start a rehab assignment 10 games prior to returning.
Bochy said the decision was made by consensus within the organization. Prior to his suspension, Cabrera batted .346 with 11 home runs, 60 RBIs and 84 runs, becoming the fifth Giants player to win the All-Star Game MVP award.
"He understands, especially with the way this club has played down the stretch," Bochy said. "We've moved on, and we're going to move forward."
Bochy declined to comment on hypothetical situations regarding injuries, but did say the Giants have enough depth in the outfield to deal with any potential injuries.
"We have a pretty big roster, and our guys have done a good job of stepping up when we needed them to," Bochy said. "I think it's for the best of this club if you've looked at how they've played and all we've been through. These guys have really done a great job. There's a reason we're in this situation."
Cabrera was acquired in the offseason from the Royals in exchange for pitcher Jonathan Sanchez and Minor Leaguer Ryan Verdugo and will be a free agent at the end of the season.
"While I am disappointed that I won't have the chance to join my team in the playoffs, I wish my teammates the best in the postseason and I'll be rooting hard for them to bring another world championship to San Francisco," Cabrera said in a written statement.
