Pierre had been signed to a minor league contract in January and was competing with Scott Podsednik, another veteran on a minor league contract, for an outfielder spot. The team said Podsednik remains with the organization and still has a chance to make the roster.
Podsedenik wasn't so sure about that possibility.
"It's not looking too good," said Podsednik, who met with team officials late Thursday afternoon.
Pierre's contract mandated that he made the 40-man roster by this Friday, or be released. Pierre, who is hitting .313 in Spring Training, was not made available for comment.
Last season, Pierre hit .279 for the White Sox and had 178 hits (26 more than any of the Phillies' players). Phillies manager Charlie Manuel said about Pierre
"When I do lineups, there are some positions I like Pierre in," manager Charlie Manuel said. "He's done a lot of things in his career. He'll stay ready and he works his butt off. He wants to play. However I want to use him, I feel he's a fit."
