First off, Leathersich now plays for the Pirates and Rosscup was traded to the Rockies for Carasiti. Carasiti and Maples are going to be competing for a slot in the pen to start the year. Butler and Zastryzny are AAA starters/MLB spot starters/emergency BP usage. I'm holding out hope that Mills can still turn into something, but it's not likely. Markey, Berg, Swarmer and Thorpe all still need innings at AAA before they can be rightly judged, as do the AA and A+ guys. Tseng and Alzolay need to stay as starters. I expect Tseng to compete for the 5th starter spot, with the Cubs going after a veteran/high risk arm for the other spot. Alzolay hopefully starts at AAA and does well. Also, this is a good year to be shopping for BP help. There are a bunch of solid BP arms that could be available: Shaw, Reed, Cishek, Davis, Hunter, Morrow, Nicasio, for example. Plus they could go after a couple former starters to convert, signing them to either minor league deals/ST invites or low cost major league deals, like Ubaldo Jimenez.
