The Cardinals have reportedly made an offer to free-agent reliever Arthur Rhodes in an effort to bolster their bullpen. Rhodes' agent confirmed Monday that St. Louis was one of nine teams that have expressed interest. "Arthur has always been one to get in place as quickly as possible," said his agent, Dan Horwits. "In this case, we want to listen to everything. ... We have offers from teams and we have others who plan to make offers fairly quickly. From that perspective, it will take time to go through them."
