Price threw 60 pitches in five innings, allowing no runs on four hits and no walks while striking out six.
"I felt good," Price said. "I was able to throw strikes, get a lot of ground balls. So that was good. It's all about getting up and down right now and we were able to do that five times with no issues.
"My legs feel good, my back, my arm, all feel real good right now. That's the main key and that's what we were able to accomplish today."
The scene on the back field at the Charlotte Sports Park looked almost surreal with Price pitching against kids, some of whom didn't look as if they even shaved yet.
"I feel like they did a really good job," Price said. "They didn't expand the zone too much. It's fun playing with the guys you're going to see in the big leagues in a couple of years and having those battles right now. It's all a process for them and that's part of it."
Price did allow that pitching on the back field did bring some challenges.
"It's definitely a little bit tougher," Price said. "There's no national anthem, there's no walkup song. There's no people in the stands. There's not a whole lot. You have to get self-motivated. It was tough. Whenever I first got here I was the only person in the clubhouse and it was pitch black. So, it was good."
Price reiterated that he still managed to get what he needed to out of the day.
"[I was] throwing everything, trying to throw strikes," Price said. "And I felt like my changeup was pretty good today. But whenever I get back out there on the main field we'll see how that goes."
Price will make three more spring appearances before starting in the Rays' season opener against the Orioles on April 2 at Tropicana Field in a 3:10 ET afternoon affair.
