Baker, 63, was back in Cincinnati late Sunday afternoon, and briefly visited his players in the clubhouse after batting practice.
"He was in good spirits," Reds left fielder Ryan Ludwick said. "He had a big smile on his face, which was a welcomed sight, obviously. He got a bunch of hugs from all of us. He seemed cool, calm and collected. Obviously, we want him here. But he's taking some time to chill out a little bit."
Backer headed home instead of staying at the ballpark for the Reds' 5-3 loss to the Dodgers on Sunday night.
"Hopefully with the day off [Monday] and him getting a good relaxing night tonight at home, he can come back on Tuesday and see how he feels. It's great news," bench coach and acting manager Chris Speier said.
Speier managed his fifth game in a row in Baker's place. The Reds clinched the National League Central title on Saturday without Baker. The club made video greetings during the clubhouse celebration.
"He looked great. I got to see him for a quick second," pitcher Homer Bailey said of Baker.
Baker's son, 13-year-old Darren, was slated to be at Great American Ball Park.
"Darren is going to be here and hang with us. That'll be good to see him," Speier said.
