The Brewers asked the Giants for Jonathan Sanchez or Madison Bumgarner in exchange for Corey Hart, according to Henry Schulman of the San Francisco Chronicle (Twitter link). Giants GM Brian Sabean is understandably hesitant to deal either pitcher.
The Brewers appear willing to deal Hart, though the right fielder has been red-hot since the middle of May. The Giants, Rays, Padres and Braves are among the teams interested in the 28-year-old. Hart has a .288/.349/.569 line with 21 homers this season after a disappointing 2009 campaign. He earns $4.8MM this year and doesn't become a free agent until after 2011.
Sanchez has a 3.47 ERA with 9.0 K/9 and 4.6 BB/9 this season. The Giants control the 27-year-old's rights through 2012. Baseball America ranked Bumgarner second among Giants prospects before the season (after Buster Posey). So far in 2010, the 20-year-old left-hander has started four games and posted a 2.57 ERA.
