Schmidt (elbow) is scheduled to throw live batting practice Tuesday, Bryan Hoch of MLB.com reports.
Schmidt has been on the injured list all season while rehabbing from the internal brace procedure he underwent last July. The 30-year-old hurler is nearing the finish line in his recovery and could begin a minor-league rehab assignment by next weekend if his live BP session Tuesday goes well. Schmidt could then return to the big-league club at some point in September, though the expectation is that he will work out of the bullpen.
