CHICAGO -- The Cubs continued to shuffle their roster in preparation for 2008, dealing outfielder Craig Monroe to the Minnesota Twins on Tuesday for a player to be named.

The Cubs acquired Monroe on Aug. 23 from Detroit for reliever Clay Rapada to add another right-handed bat, and he hit .204 with a home run and four RBIs in 23 games in Chicago. Between the Tigers and Cubs, Monroe batted .219 with 12 homers and 59 RBIs in 122 games in 2007.

The Cubs had planned to non-tender Monroe next month, and allow him to become a free agent. By dealing him to the Twins, the team will receive a low-level prospect in return.

The Cubs also announced they have activated right-handed pitchers Angel Guzman and Mark Prior from the 60-day disabled list. Guzman underwent Tommy John surgery on his right elbow Sept. 6, and will spend most of the winter rehabbing at the team facility in Mesa, Ariz. He could return in June or July.

Prior underwent arthroscopic surgery on his right shoulder in late April. The 27-year-old pitcher could be back on the mound late in 2008.

The Cubs began the offseason makeover on Monday when they dealt outfielder Jacque Jones to Detroit for infielder Omar Infante. The Major League roster now stands at 38 players.
