LAWRENCEVILLE — Atlanta Braves third baseman Chipper Jones reported no problems with his surgically repaired left knee after taking batting practice on Tuesday. Jones, who is on the 15-day disabled list following arthroscopic surgery to repair a torn meniscus, estimated he took "50 to 60" swings before the Braves played their minor league All-Stars in an exhibition at Triple-A Gwinnett. "I couldn't be happier," he said.
