This is news to me – new, old news to be precise.
One of the craziest rumors at the winter meetings in December centered on the Cubs — after completing a Jake Peavy trade — sending Zambrano to the Sox.
Sources from both sides of town shot down the rumor, and Peavy never was dealt to Chicago. Still, it was thought-provoking. Certainly, Zambrano and Guillen have toyed with the idea of ”Big Z” on the South Side. CHICAGO SUN-TIMES.
Mind you, this was written in the context of a Zambrano-loves-the-Sox article, so it’s possible that “rumor” is being very liberally applied. But still, I never heard about this rumor.
