Dan Duquette has made a lot of changes to the Orioles in his first offseason as the Executive VP of Baseball Operations. Since signing with the team, he has added 12 players to the 40-man roster, not to mention his minor league signings.
The Orioles will be a very different team because of all of the changes. The starting rotation and bullpen were the worst in the majors in 2011 and will likely see a lot of fresh faces in 2012. The team will rely on a combination of the Orioles' developing pitchers and veterans from other teams and other countries.
Jeremy Guthrie, Luke Scott, Vladimir Guerrero, Cesar Izturis and others are gone and a new group is coming. We'll have to see if these changes result in more wins.
Here are grades for all of the major offseason additions.
