6:36pm: MLB.com's Mark Bowman responds to Rosenthal's report, writing that even though they view the Brewers as a potential trade partner, the Braves aren't interested in Hart. If Atlanta were to work out a deal with the Brewers or Angels, Bowman thinks they might be more likely to trade for prospects than a major-league outfielder.
5:58pm: The Atlanta Braves are shopping Derek Lowe, but not having much success so far, according to Ken Rosenthal of FOX Sports.
Rosenthal suggests that Lowe's contract situation (he'll make $15MM in each of the next three years) and his 2009 struggles (4.67 ERA in 34 starts) are discouraging teams' interest in the right-hander. The Braves, however, are still optimistic, believing that John Lackey is the only free agent starter on this year's market more appealing than the 36-year-old Lowe.
Rosenthal names the Angels and White Sox as potential trade partners. According to his sources though, the most serious discussions the Braves have had about Lowe were with the Milwaukee Brewers, involving Corey Hart. It doesn't sound like those talks are necessarily dead, but the Brewers would expect Atlanta to take on a large chunk of Lowe's salary, and even then aren't entirely sure they'd want him.
