CHICAGO — The Chicago Cubs acquired right-handed reliever Kevin Gregg from the Florida Marlins today for minor league pitcher Jose Ceda.

Gregg was 7-8 with 29 saves and a 3.41 ERA in 72 relief appearances for the Marlins last season, holding batters to a .203 average.

What Gregg's role will be with the Cubs is unclear. Closer Kerry Wood is a free agent, and Chicago already has a top setup reliever in Carlos Marmol.

Greg joined the Marlins before the 2007 season in a trade from the Angels and had 32 saves in 74 relief appearances that year. He has an 18-21 major league record with 62 saves with a 4.00 ERA in 271 big league games — all but eight relief.

The right-handed Ceda, who is only 21, was 4-3 with nine saves and a 3.83 ERA last season in minor league stints at Class A Daytona and Double-A Tennessee.
