The Florida Marlins are considering trading righthander A.J. Burnett in a blockbuster move that would alter the pennant races in both leagues, Sporting News has learned. The Marlins are engaged in preliminary discussions about Burnett with the Orioles and a second, unidentified American League club. Their goal in trading Burnett, who will be a free agent at the end of the season, would be to obtain three major league parts -- a young starting pitcher, a quality reliever and a lefthanded hitting outfielder. Few teams would be willing to pay such a steep price. The Red Sox, awaiting the return of righthander Curt Schilling, are not currently pursuing a trade for a starting pitcher, be it Burnett or Giants righthander Jason Schmidt. The Yankees could get involved for Burnett if they were willing to trade setup man Tom Gordon and righthander Chien-Ming Wang, but that move could do more harm than good. The Tigers have had past interest in Burnett. The Angels, White Sox and Twins are not believed to be currently interested.
