The move, which is not expected to be announced until next week, would save the Cubs between $5 million-$6 million — money they could devote to the pursuit of a left-handed hitting outfielder such as their primary target, free agent Milton Bradley, a switch-hitter.

The cash going from the Cubs to the Rockies would be less than $1 million, sources say. The Rockies would take on Marquis' $9.875 million salary for next season while the Cubs would assume Vizcaino's $3.5 million obligation.

Vizcaino's contract also includes a $4 million option or $500,000 buyout for 2010. The option will become guaranteed if Vizcaino appears in 68 games next season.

While several sources indicated that the deal is all but completed, another source with direct knowledge of the talks said the teams have merely engaged in conversation.

The Rockies have a surplus of right-handed relievers and they long have had interest in Marquis, a sinker-baller who is 3-0 with a 2.51 career ERA at Coors Field. The team also had pursued free-agent right-hander Tim Redding, who is looking for a two-year contract.
