The Celtics on Wednesday signed PF Esteban Batista to a non-guaranteed contract.
He’ll compete for a roster spot in training camp and chances are he’ll latch on as one of the team’s final 15 players. Batista, a 6-foot-10, 270-pound Uruguay native, played sparingly for Atlanta last season, but averaged a tournament-best 12.4 rebounds and 20.8 points during the recent FIBA Americas Championship in Las Vegas.
