From Ken Rosenthal of FoxSports.com . . . One GM with interest in free-agent outfielder Dave Roberts anticipates that the Brewers will make a strong push to sign Roberts to bat leadoff and play center field. 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. Bill Hall, who impressed GM Doug Melvin with his outfield play during the major-league All-Star tour of Japan, is perhaps the Brewers' leading candidate to play left.
