The two spread apart as far as 60 feet, and Blanton said he felt good after the session.
Beyond that, he does not know when he may toss a bullpen session or when he'll throw next.
"I don't know if that's a day-to-day thing," he said. "I'm sure they have some kind of plan."
Blanton has been on the disabled list since May 23, retroactive to May 16, with inflammation in his right elbow. The malady also forced him to the DL in April.
