WASHINGTON -- Scott Schebler returned to the Reds from his rehab assignment on Friday, but interim manager Jim Riggleman said Schebler may not be activated off the disabled list until September because of throwing issues.
Schebler, who landed on the disabled list July 18 with a sprained AC joint in his right shoulder, is back from Triple-A Louisville because his 20-day rehab limit ended. After Schebler rests his arm for about a week, Riggleman expects that the 27-year-old will go on another rehab stint before returning to the Reds.
Schebler served as the designated hitter in six of his seven rehab games with Louisville. He started in left field in one game, but he felt discomfort throwing to the infield.
Riggleman said Schebler's swing isn't affected by his injury, as he hit 6-for-23 with one homer, five walks and three strikeouts during his rehab assignment.

"There's obviously something in there that's not allowing him to feel like he can play defense and throw," Riggleman said.
Before his setback, Schebler hit .278 with 12 home runs in 76 games with Cincinnati. Jesse Winker, another left-handed hitter who was hitting .299, was ruled out for the rest of the season with a right shoulder subluxation on July 26.
Mason Williams, Preston Tucker and Brandon Dixon have received more playing time in Schebler's absence. Riggleman said his left-handed hitters, like Williams and Tucker, need to produce to complement Joey Votto and Scooter Gennett in the middle of the lineup.
"Most teams, to be productive, you need your left-handed hitters doing something," Riggleman said.
Schebler also missed 10 games in April due to an ulnar nerve contusion in his right elbow.
