CHICAGO -- In the immediate wake of his no-hitter against the Brewers on Sunday, Cubs pitcher Alec Mills said he needed to go back and watch video of the final out. At the time, he was too overwhelmed to even know how he reacted in the moment.

After shortstop Javier Báez fired the ball to first baseman Anthony Rizzo for the 27th, history-making out, Mills stuck his tongue out before breaking into a smile. Prior to Tuesday's game against Cleveland, Mills laughed when asked what he thought of what he saw on the replay.

"Yeah, I have no idea where that came from," Mills said. "I don't think I've ever stuck my tongue out in my life. I don't know what that was. I don't remember much about it, so it's just what happened, I guess, in pure joy. Obviously, it was a lot of fun.

"I think the big thing for me was seeing how much fun everybody else had celebrating. That meant a lot to me."

Mills said he had more than 320 text messages in the aftermath of the 16th no-hitter in Cubs history. He heard from Cubs chairman Tom Ricketts and president of baseball operations Theo Epstein, among others. Texts and calls flooded in from family and friends.

On the off-day on Monday, Mills tried to return as many messages as he could while his son took a nap.

"I sat down on the couch and was just like, 'What did I just do?'" Mills said. "I think it was starting to set in a little bit. ... It's just overwhelming with how many people reached out. I'm obviously super thankful and very blessed to have that many people."

When Mills stepped off the team bus following the trip back from Milwaukee, he was welcomed by his wife and son. And then, the Mills family had a low-key celebration after a hectic, historic day. The pitcher's wife ordered a pizza from Pequod's, and Mills gave a rave review.

"I hadn't tried it yet. It was really good," Mills said. "I think it might be my favorite pizza I've tried in the city so far. So that was a cool little Chicago-style way to celebrate. So that was fun."

Chatwood has setback in comeback
Cubs manager David Ross noted Tuesday that right-hander Tyler Chatwood (10-day injured list, right forearm) has not responded well to his recent throwing program, removing the pitcher from the equation for at least the regular season.

"Chatty is going to be a little bit," Ross said. "I don't want to make a statement that his season's over, but I would say that there's definitely a lot of caution in, one, the health of the player, and his future.

"He's going to continue to try to push himself. And then, I'm not saying there's not a scenario where we're in the World Series and he's in the bullpen. Things can change from now until then. But right now, he's on the shelf for a little bit."

Worth noting
• Lefty José Quintana (10-day IL, left lat) threw a bullpen session on Monday and will have a light mound workout again on Wednesday, per Ross. A simulated game could follow for Quintana, who still has a chance to rejoin the bullpen before the end of the season.

"We'll have to see how things continue to progress," Ross said. "We'll probably be bringing him in out of the bullpen like we tried last time. That worked pretty well, and try to build him back up a little bit."

• For Tuesday's game, Ross moved Báez to the sixth slot of the starting lineup and opted to keep Willson Contreras in the cleanup spot. Over the final two weeks, the manager said he might try a few other batting order tweaks to try to find more offensive "continuity."

"I definitely went with the trust factor early on -- most of the season," Ross said. "And letting these guys feed off each other's at-bats and how the lineup works. But now we're starting to get a clear picture of who's having the good at-bats, who's having a good season, who's coming along."

• Lefty Andrew Chafin (10-day IL, sprained finger on left hand) is scheduled to throw a simulated game on Wednesday, per Ross.

Quotable
"Let's just put it this way: No one's ever recognized me in the streets so far in Chicago. I don't know if the chances of that may be a little higher now." -- Mills, on the attention that comes with throwing a no-hitter
