"The left-handed pitcher most in demand at the winter meetings is not either of the top free agents, C.J. Wilson or Mark Buehrle.

No, the lefty generating the most attention is the Athletics' Gio Gonzalez, who is attracting trade interest from nearly a dozen teams, major league sources say.

The Tigers, Diamondbacks, Marlins, Reds and Phillies are the known suitors for Gonzalez, according to sources.

Other clubs including the Blue Jays, Nationals, Red Sox, Rangers and Rockies also are known to be pursuing starting pitching and likely have some interest in Gonzalez. The Yankees have had only minimal conversations with the A's about Gonzalez and are not a factor in the discussions, a source said."
