Bruntlett is the most recognizable name on the list and Walker is perhaps the most surprising.
Bruntlett came over to the Phillies in the deal that brought Brad Lidge to the Phillies prior to the 2008 season. He's perhaps best known for scoring the winning run in games three and five of the 2008 World Series, or perhaps for the unassisted triple-play that he pulled off during the 2009 season.
In his time with Philadelphia, Bruntlett hit just .202, including a disastrous .171 with the Phillies in 2009. Bruntlett has hit .231 in seven major league seasons and was a .250 hitter prior to coming to the Phillies.
Walker started the season at Triple-A Lehigh Valley, but joined the Phillies in June and went 2-1, 3.06 in 32 games with the big league club. The 33 year old right-hander has pitched in 262 major league games and has pitched for the Mets, Giants and Rays in addition to the Phillies. He holds a career 4.32 ERA in the majors.
Ennis, Hoover and Tracy were September additions to the roster. Ennis, was immediately placed on the 60 day DL when he was added to the roster, which was basically a procedural move to give the Phillies flexibility to use another roster spot for the post-season if they needed one. Hoover and Tracy spent the season at Lehigh Valley and were important players for the IronPigs squad.
Tracy, who has been with Lehigh Valley since the franchise started play in 2008, hit .417 in 12 at-bats with the Phillies in September and hit .254 with 96 RBI and a franchise record 26 home runs for Lehigh Valley. Tracy, who turns 36 in December, is a left-handed hitting first baseman and has played in the majors for Montreal and Colorado prior to his time with the Phillies.
Hoover, 33, has played in the majors with both Tampa Bay and Florida and went 3-for-4 in his time with the Phillies this season. Overall, he is a career .256 hitter in 31 major league games. As a catcher, Hoover took over most of the catching duties for Lehigh Valley when Lou Marson was dealt to Cleveland in the Cliff Lee trade last July.
The Phillies have contacted the agents for Ennis, Hoover and Tracy to express an interest in bringing them back on minor league deals. Bruntlett and Walker won't be returning to the Phillies organization.
