The Tampa Bay Rays left-hander, who was put on the disabled list for the first time in his career May 16, made 35 throws in right field before Monday's game against Miami.
"I felt really good ... it felt normal," Price said. "It was a very positive day. Feeling as good as I did, it's a definitely a relief."
There is no timeline for when Price will return, but the injury is not expected to pose a long-term problem.
"We don't want any setbacks," Price said. "I want to be able to come back and stay back, and that's what we're doing."
Price is 1-4 with a 5.24 ERA after going 20-5 with a 2.56 ERA in 2012. The Rays have lost seven of his nine starts after going 21-10 in his 31 starts last year.
