• An MRI of right-hander Zach Putnam's right elbow confirmed he has a bone spur. Putnam was placed on the disabled list on Wednesday.
• Kyuji Fujikawa, who underwent Tommy John surgery on his right elbow on Tuesday, rejoined the Cubs on Thursday. Dr. James Andrews did the procedure in Pensacola, Fla.
• Reds manager Dusty Baker compiled a 322-326 record in four seasons as the Cubs manager (2003-06), including a trip to the playoffs his first season and a 96-loss season his final year.
"I've been through it," Baker said Thursday. "Any manager that's been around has been through it. Everybody's like, 'Shake up the lineup.' You shake it up, you've still got the same stuff. And I'm cleaning it up, of course.
"It's very frustrating," Baker said. "You're not sleeping much. You're trying to figure out something that you've already figured, and it's hard to accept that maybe you're not good. Sometimes you're not good. You've got some good players, but you might not be good overall."
Baker noticed empty seats at Wrigley.
"I don't think about that," he said. "I'm on the other side now. But it's different. I don't know if it's the weather, or if school's not out, but it's always a little different early, and then the weather gets nicer."
