ESPN is reporting a complicated trade that’s resulted in, among other things, the addition of Corey Patterson to the St. Louis Cardinals’ roster:

CHICAGO — The Chicago White Sox traded pitcher Edwin Jackson and utilityman Mark Teahen to the Toronto Blue Jays.

The White Sox will receive reliever Jason Frasor and pitching prospect Zach Stewart.

A short time later Wednesday, the Blue Jays turned around and traded Jackson to the St. Louis Cardinals in an eight player deal that netted Toronto Colby Rasmus, sources told ESPN The Magazine’s Buster Olney.

The Cards sent Rasmus Trever Miller, Brian Tallet and P.J. Walters to the Jays for Jackson, Marc Rzepczynski, Octavio Dotel and Corey Patterson.

The clear winner in this trade is, of course, Colby Rasmus, who finally gets to escape from under the malevolent thumb of Tony LaRussa.
