Bochy said he didn't have any details about the family problem Cueto is facing.
"That's something Johnny can talk to you about," Bochy said.
Bochy added that he was not concerned about Cueto falling behind the other starting pitchers in camp, but it did put into question his ability to pitch for the Dominicans in the upcoming World Baseball Classic.
The defending champion Dominicans open Pool C in Miami on March 9 against Canada. Team USA and Colombia are the other teams in the bracket at Marlins Park. Cueto is listed on the regular roster. Cueto last played for the Dominicans in the 2009 WBC.
Cueto has been throwing at the Giants' academy in the Dominican, and Bochy has seen video of some of the sessions. He also said that he planned to call Cueto after he was finished with the media to at least get tentative answers to some questions.
"I mean, we're fine. I've said this the last couple of days," Bochy said. "We started early, and he'll have plenty of time to get ready. Now the question is, will he be ready for the [Classic]? That's the question we're going to have to answer now. That's why we're going to try to call him, get a hold of him and see exactly where we're at. He'll be honest with us."
Cueto was a reliable pitcher for the Giants last season, his first in San Francisco after signing a six-year, $130 million guaranteed contract as a free agent. He was 18-5 with a 2.79 ERA and 1.093 WHIP in 32 starts.
The Giants open the Cactus League season at home Friday against the Reds, Cueto's former team.
