The visiting clubhouse at U.S. Cellular Field didn't open until about 4 p.m. CT, approximately 20 minutes late.
Yost said he wouldn't disclose what was said in the meeting.
"It's a meeting between us," Yost said. "Like I always tell you: If I wanted you guys to be part of it, I'd have invited you."
On Sunday, when the team designated infielder Yuniesky Betancourt for assignment in part because he was upset about his lack of playing time, Yost spoke to reporters about the team's mission of changing the franchise's mindset.
"We have been living in a losing culture here for many years. We cannot get over the hump. And in order for us to get over the hump, we have to have 25 guys who are solely invested in one goal, and that's turning this organization around to become a champion. That's it," Yost said Sunday.
"It's not about, 'How much do I play?' It's not about, 'Do I have a job?' This is about 25 guys with one goal: That we're going out to try to win this baseball game tonight, and you have that goal night in, night out. And if you've got anybody else that is not on page with that, we will never change our culture. It's about 25 guys who respect each other, 25 guys that have the same common goal. That's how we're going to turn this losing culture into a winning culture."
