Braves place Jones on DL with strained oblique
The moves cleared roster spots for newly acquired infielder Willy Aybar and reliever Danys Baez. Sosa will become a free agent after 10 days if he is not traded by Atlanta or claimed on waivers by another team.
Sosa couldn't hold jobs as a starter, closer or setup man this season. He blew three of six save opportunities in his brief stint as a closer.
Sosa was 3-10 with a 5.46 ERA overall, a dramatic decline from his surprising success in 2005, when he was 13-3 with a 2.55 ERA.
"He obviously hasn't done for us what he did last year," Braves general manager John Schuerholz said. "He did a great job for us last year and it hasn't worked as well this year."
The Braves also transferred outfielder Brian Jordan from the 15-day disabled list to the 60-day DL Sunday.
Jones said he didn't try to talk the team out of placing him on the DL with the oblique injury.
"I didn't have any grounds to fight it," Jones said. "I took four days off and it did feel better but it just wasn't ready. I'm going to need probably the better part of the DL stint to get it completely healed."
Jones also was on the disabled list from April 10 to April 25 with a sprained right ankle and knee, and he also has had to play through problems with his feet for the second straight year.
Jones' latest injury comes as the Braves are completing a disappointing six-game homestand, losing series against Florida and the New York Mets.
"It seems like this year, if I'm not in there, we just can't get anything rolling," Jones said. "That's what stings. The offense was rolling pretty good, everybody was in there firing on all cylinders and I was helping lead the way."
Sosa, 28, received a salary increase from $650,000 in 2005 to $2.2 million this season.
When asked his plans and his reaction to being designated for assignment, Sosa said "I don't know. ... I don't want to talk about that right now."
