With the Marlins in "sell" mode, about 25 scouts sat behind home plate Tuesday night at Marlins Park. If they were studying Marlins starter Mark Buehrle as a possible trade chip, chances are they won't be recommending any deal based on the left-hander's performance in Miami's 4-3 loss to the Atlanta Braves. Buehrle is among the best pitchers in baseball when it comes to avoiding walks. He came into the game having issued 19 in 125 2/3 innings, the third-lowest total among pitchers in both leagues.
