Last Thursday vs. the Rockies, Winker was injured in an outfield collision with Jake Cave trying to catch a fly ball. He was given a few days off.
Winker, 23, was relieved the injury wasn't serious.
"Absolutely, especially when you're a hitter and you go to turn and hit a ball," Winker said. "It felt good today and I was very pleased with that. I feel like I'm progressing the way they want me to and the way I want to, too."
Winker, who is ranked as the organization's No. 1 prospect by MLBPipeline.com, also has done some straight-line running without issue. His return to the lineup isn't imminent but he hoped to resume competing for a big league roster spot.
"It'll still probably be a few days before we consider him ready to play," Reds manager Bryan Price said.
More notes from Wednesday:
• The Reds have a "B" game scheduled vs. the White Sox in Goodyear at 12:30 p.m. ET on Thursday. Rotation candidate Cody Reed is the scheduled starting pitcher.
• Right-handed reliever Carlos Contreras, who was optioned to Triple-A Louisville on Monday, cleared waivers and was released on Wednesday. His departure leaves the Reds' 40-man roster at 38 players
