Reporting from the Winter GM Meetings, Ken Rosenthal says:
By signing Roberts or free-agent center fielder Juan Pierre, the Brewers further would increase their outfield depth, raising the possibility that Geoff Jenkins and/or Kevin Mench could be traded. Roberts, however, is in heavy demand; the Mets, Braves, Dodgers and White Sox are among the other teams interested.
Please no. Let one of those teams with money to burn, burn their money on Roberts. Roberts on the Brewers is a bad idea.
