SAN FRANCISCO -- One day after Derek Holland publicly aired his frustration with the decision-making of the Giants’ front office, president of baseball operations Farhan Zaidi and manager Bruce Bochy responded to the veteran left-hander’s comments and expressed disappointment that he opted not to communicate his concerns internally.

“When a guy isn’t quite performing like he normally does, maybe there is something going on,” Bochy said. “We had to do what’s best for him, what’s best for the club. Sometimes you have to take it out of their hands because they want to play through it. I think it was frustration.”

Holland’s critique came after he was informed that he would be moving to the bullpen after posting a 6.75 ERA over seven starts this season. Bochy said he spoke with Holland on Sunday morning and reiterated his preference that the club keep its grievances behind closed doors. Zaidi also texted Holland and planned to meet with him later in the day.

“I have an open-door policy,” Bochy said. “If there’s frustration, I want them to come to my office. I’ve always said my preference is we air things out internally. That’s what’s important to me, to the team, to the organization. That’s my biggest disappointment.”

Added Zaidi: “I think you’d like to create an environment where guys feel comfortable talking about their concerns in-house. To the extent that guys don’t feel comfortable, that’s on me.”

Still, Zaidi acknowledged that there’d likely be less discontent if the Giants didn’t enter Sunday sitting at the bottom of the National League West with a 16-23 record.

“I just think it’s all based on results,” Zaidi said. “If we’re 23-16, I don’t think we’d be sitting in this room right now. I understand it. I’m as frustrated as anybody. But again, I want to establish a culture of accountability where people are kind of looking in the mirror and asking what they can do better. That’s the attitude we adopted in the front office, understanding that the results we’ve had so far are unacceptable.”
