5:52pm: There's some tension between the Braves and Brewers, since Atlanta initially heard that Cain was available and are now hearing he isn't a trade chip, according to Jerry Crasnick of ESPN.com (Twitter links). Brewers GM Doug Melvin told Crasnick he has to be open to deals for any player, though.
2:27pm: The Brewers don't want to and aren't looking to move Cain but will listen, tweets Tom Haudricourt of the Milwaukee Journal-Sentinel.
12:06pm: Our hunch was correct; MLB.com's Mark Bowman reports that the Braves are among the teams showing interest in Cain.
Cain, 25 in April, is expected to compete for the Brewers' starting center field job next year with Carlos Gomez and Chris Dickerson. He did a nice job in 158 big league plate appearances this year and had a .402 OBP in 380 minor league PAs. Pure speculation, but maybe the Braves could match up if they're not keen on trying Nate McLouth or Jordan Schafer in center next year.
