Chapman threw 25 pitches and reported no issues.
"It went real well," Chapman said via interpreter. "I was throwing normal as a bullpen. When you throw a bullpen, you don't throw 100 percent, you never do that."
Chapman was supervised by pitching coach Bryan Price, assistant pitching coach Mack Jenkins and two trainers. Price was pleased with what he saw.
"He threw the ball well -- no inhibitions, no shoulder fatigue," Price said. "It was crisp. Repetition certainly helps. It's hard to go a week without throwing off of the mound and feel completely acute. But the arm really worked well. The velocity and rotation was good."
Chapman, 24, struggled in his last two appearances for the Reds and hasn't pitched since walking three batters in two-thirds of an inning on Sept. 10 vs. the Pirates. But the shoulder issues seem to be behind him.
"It feels good," Chapman said. "I feel like I need to throw 2-3 more times to work on my command. I don't feel like I have the command the way it is."
Chapman is scheduled to play catch on Thursday. It's possible he could return to closing games sometime this weekend, when the Reds host the Dodgers.
"Once we get home, we'll take a look at it," Price said.
