Ryan Dempster and team president Theo Epstein met Wednesday to discuss potential trades for the Chicago Cubs pitcher, according to a source with knowledge of the situation. Dempster is in the final season of a four-year, $44 million deal that pays him $14 million in 2012. As many as 10 teams have interest in Dempster, who has 10 and 5 rights that allow him to veto a trade.
