He'd heard about Major League pitching, not Major League partying.
"I didn't expect it," he said. "We just put some new lights in here, and a new disco ball. I guess it's against tradition. Usually when you win, you just expect it. Here we're celebrating every win. There's nothing wrong with it.
"Guys here want to have fun, I want to have fun," he said. "It's much more fun when you win."
General manager Jed Hoyer gave manager Joe Maddon and the players his blessing.
"It is hard to win games, there's no doubt," Hoyer said. "I like the fact that they have a lot of fun. We have a young team, so it adds some new life to it. Joe and [bench coach] Davey [Martinez] really encourage it. [Anthony Rizzo] may be the ringleader. It's a lot of fun, and hopefully they'll have a lot of chances to continue it. If it starts to break the budget, I guess it's a good thing."
Maddon feels it's important to celebrate.
"I think the more you celebrate, obviously, there's that camaraderie component that goes with it, and then furthermore, you're looking forward to celebrating again tomorrow night," Maddon said. "It's a lot of fun. So I don't know why other teams don't do it. They think it's nonprofessional; I think it's very pro, actually."
The loud celebration does let players "cherish the moment," Maddon said, "because it's not easy to win a Major League baseball game, and to win them 90-plus times is very difficult in the same season."
Bryant compared it to Little League games, after which players are rewarded with snacks.
"If we go out there and pretend to be in Little League, we'll win a lot of ballgames," Bryant said.
• Seeing the White Sox and Orioles play without any fans in the stands made Maddon stop to say thanks to the fans outside Wrigley Field on Wednesday.
"When I walked in today, I made sure to stop and sign every autograph on my way in," Maddon said. "That game [in Baltimore] really emphasizes and reveals the role of the fans in our game. And sometimes it could be taken for granted.
"To play a baseball game with nobody in the stands would be very not fun. I wouldn't want to do it. What would be the appeal? ... I think that game, more than anything, today illustrated the importance that fans play in our game. That was my takeaway from watching that ... and I'd like to hope or believe that the players stop and reflect on that a little bit, because I think sometimes we do get a little bit negative in that regard."
Maddon has spent plenty of time in the Minor Leagues, playing in front of small crowds.
"I think I have a great appreciation of the fans, but I hope now I have a greater appreciation for our fans and all baseball fans based on that event today."
