Nunez was primarily a defensive specialist this past season and started games at third base when groundball pitcher Jamie Moyer started. He hit .234 in 136 games for the Phillies in 2007 and hit .221 in two seasons with the Phillies.
Barajas started the season splitting time behind the plate with Carlos Ruiz, but was supplanted by Ruiz after Barajas landed on the DL. He hit .230 with 4 home runs and 10 RBI in 48 games in his only season with the Phillies.
Nunez and Barajas will both enter the free agent market this off-season.
The Phillies also designated right-hander Kane Davis for assignment. The 32 year old signed with the Phillies as a minor league free agent last October and pitched well at Triple-A Ottawa this season, but stumbled in his opportunity with the big league club late in the season when he went 0-1 with a 5.56 ERA in 11 games.
The Phillies have also reached contract deals with all of their coaches except bench coach Jimy Williams, who has been mentioned for other opportunities around baseball, including a couple of managerial openings. If none of those openings pan out for Williams, it is likely that he will return as Charlie Manuel's bench coach in 2008.
