That starting rotation is according to the press release and it mentions that Mitch Atkins will get Iowa's opening day start. Also, Triple A and Double A rosters should max out at 24 (according to AZ Phil at least) so there's a good chance two players are headed to the DL right away unless there's been a rule change. Then of course, why wouldn't they just sit back in extended spring training?
Besides re-signing free-agent RHP Chad Fox to a minor league contract, the Cubs have signed three minor league free-agents in recent days, including one player who (as things stand now) actually has a legitimate chance to make the Cubs 2009 Opening Day Roster.
