The Boston Celtics continue to fill the spots around their new trio of superstars Kevin Garnett, Paul Pierce and Ray Allen. On Thursday, they added Esteban Batista and Dahntay Jones to their training camp roster that will be touring Italy this month. Both signed non-guaranteed contracts.

Esteban Batista had a fantastic performance in the recent FIBA Americas tournament, averaging 20.8 points and 12.4 rebounds a game, and was garnering interest from several teams including the Charlotte Bobcats, Indiana Pacers, and Phoenix Suns.

The 6-10, 270lb Batista has spent the last two seasons on the Atlanta Hawks bench and was hoping to catch on with an NBA team this season. Though Batista turned the Celtics down earlier last week, the Celtics were the most excited to have Batista on their roster.

“Doc (Rivers) and Danny (Ainge) really pursued him and made him feel wanted,” said Batista’s agent, Mark Cornstein. “I think he’s a great fit for that organization. What he wants and needs is an opportunity, and I think they can provide him with that.”

The Celtics hope that Batista’s summer performance will bleed into this upcoming tournament in Europe. If the Uruguayan star can continue to grab offensive rebounds (he led the FIBA Americas tournament in both offensive rebounding) to give Pierce, Ray Allen and Garnett extra shots, and show the scoring touch he displayed this summer, Batista may prove invaluable and force Boston into a guaranteed contract for the 2007-08 NBA season.
