Kinzer, who is attending this week's general managers meetings, said he will meet with other clubs this week about Ramirez's future, but that he does not plan to speak to the Cubs.
"That ship has sailed," Kinzer said. "We have a lot of interest in Aramis from different teams. But the Cubs will not be one of them."
Kinzer, who also represents free-agent shortstop Rafael Furcal, said he is seeking a three- or four-year contract for Ramirez, a 33-year-old Dominican native. Ramirez hit .305 with 26 home runs and a team-high 93 RBIs for the Cubs in 2011.
According to a major league source, Kinzer had a meeting with Milwaukee Brewers general manager Doug Melvin on Monday afternoon. If Brewers first baseman Prince Fielder leaves as expected through the free-agent process, the club will be looking to replace his production. Fielder hit .299 and slugged 38 homers and 120 RBIs for the Brewers in 2011.
Fielder's agent Scott Boras, who is also in Milwaukee, said Monday that he will schedule meetings with Cubs president of baseball operations Theo Epstein and general manager Jed Hoyer to get a feel for where the Cubs stand under their new management.
"Prince has hit well at Wrigley Field and he's done well in that division," said Boras, who also represents Cubs free agent Carlos Pena. "(The Cubs and I) haven't talked yet, but we will."
Pena hit .225 with 28 homers and 80 RBIs for the Cubs last season.
On Monday, Kinzer reiterated his annoyance with comments Cubs broadcaster Bob Brenly made on "The Waddle and Silvy Show" on ESPN 1000 in early October, including that Ramirez was not a clutch hitter.
"They don't give out Silver Slugger awards to Punch-and-Judy hitters," Kinzer said about Ramirez, who won the NL award in 2011. "Everybody with the Cubs has always been tremendous for the whole time that Aramis was there. It was a great relationship. You can ask his managers why they don't feel that way (that Brenly felt). You can ask (former Cubs GM) Jim Hendry why he doesn't feel that way. Why he had a personal attack on Aramis, I don't understand that. For a broadcaster to come out and say that, I thought it was very low-class."
