With the 76ers set to begin training camp today at St. Joseph's University, four free agents were officially added to the team's roster to bring it to 17 players.

That does not mean any of the newcomers will make the team, however. But they were there yesterday when the Sixers held their annual media day at the Wachovia Center.

"We have 13 guaranteed contracts, and we may keep 14 [players on the roster]," said Sixers president and general manager Ed Stefanski. "If someone shows in camp, we may keep 14."

Among the hopefuls are shooting guard Dionte Christmas and point guard Sean Singletary, native Philadelphians who played in college at Temple and Virginia, respectively. The 6-foot-5 Christmas is a rookie while the 6-0 Singletary played for Houston, Phoenix, and Charlotte last season, after being picked by Sacramento with the 42d overall pick in the 2008 NBA draft and traded.

Also on board to try to win a job are 6-9 forward Brandon Bowen and 6-10 forward/center Stromile Swift. Bowen, who attended Georgetown, has played overseas and in the NBA Developmental League since going undrafted in '06. Swift comes to the Sixers as a nine-year pro who has played in 547 career games.

"I feel fortunate to have been around some good guys, and played under some good coaches," said Swift, who has been on five different teams since being selected by Vancouver with the second overall pick in the 2000 NBA draft. "I just want to bring what energy I can bring."

Due to an early-season injury, and the sickness and eventual death of his mother in January, Swift played in just 19 games last season for New Jersey and Phoenix.

A leaper, Swift has career averages of 8.4 points, 4.6 rebounds and 1.25 blocks in an average of 19.8 minutes per game. If Swift can show he can give the Sixers what the departed Theo Ratliff did last season - in limited minutes off the bench - there could be a spot on the roster for him.

"He's an interesting name," Stefanski said. "He's extremely athletic and big, and, in our style, he can run and block shots."

After what he went through last winter, Swift is eager to reestablish himself. "I'm excited," Swift said. "I've been waiting to get back, and I want to show people that I can still play."
