According to major-league sources, the St. Louis Cardinals have emerged as serious players for A.J. Burnett. The Cardinals had interest in Burnett the last time he was a free agent, in 2005.

After acquiring shortstop Khalil Greene from the Padres, Cardinals' general manager John Mozeliak told the St. Louis Post-Dispatch, "We're going to focus on pitching."
