Stripling (back) is scheduled to throw a bullpen session Wednesday and another several days after, MLB.com reports.
The veteran right-hander has been on the injured list since last Tuesday with a lower-back strain, and Wednesday will mark the first time he'll attempt to do any throwing since that point. If all goes well with the session, Stripling is slated to repeat the process at some point after the Athletics begin a homestand Friday against the Yankees. Despite the recent developments, a return for Stripling before the end of the regular season isn't a certainty in the view of manager Mark Kotsay, per the Associated Press.
