CHICAGO -- Reds manager Dusty Baker, hospitalized after being diagnosed with an irregular heartbeat, was underdoing another test Thursday and could return to Cincinnati on Friday.
Acting manager Chris Speier said doctors would look at test results to see if everything was OK, and then perhaps give Baker the go-ahead to fly back to Cincinnati the following day. The Reds, on the verge of wrapping up the NL Central, begin a series Friday against the Dodgers.
Speier, who ran the team for a second straight game as the Reds swept the Chicago Cubs and clinched a playoff spot, said he hadn't talked to Baker on Thursday because he was having the test. He did talk to him Wednesday night and said he sounded good.
"I worry about Dusty and everybody in that clubhouse was really worried last night," Speier said. "You don't just go to the hospital for a cold or anything like that. And I still feel that way. ... My thoughts are more about Dusty than this game."
Baker left Wrigley Field in street clothes more than two hours before Wednesday night's game, and it was initially announced he would have chest X-rays to "rule out pneumonia."
The 63-year-old Baker managed his 3,000th career game Tuesday night against Chicago. He has also managed the Cubs and Giants.
Speier said he saw no warning signs that Baker was not feeling well.
"I think everybody at this time of year, everybody is a little beat up, everybody is a little tired," Speier said. "He's done it for so long. He's a little bit used to it, but I was thinking about it last night: `Wow, he's done this for 3,000 games."
The Reds' magic number is now at two as they seek their second NL Central title in three years.
Cubs first-year manager Dale Sveum said the job is demanding.
"Whatever health issues we all have, you never take your health for granted," Sveum said. "All our wishes and all our prayers and everything go out. Hopefully, everything's good with Dusty because he's a great guy and the rest of this year is going to be very important for him to be around and healthy."
