"It felt good," said Price, noting that he had to fight through some trepidation.
"Coming off something that never really happened before, you don't know what to really expect," the 27-year-old said. "That's the way I was going out there. I felt really good playing catch, and I felt really good when I got out there on the mound. The only thing I felt was a little bit weak in my legs, and that's because I haven't been using them much."
Maddon said he will wait to see how Price feels on Wednesday before naming him as Friday's starter. But Price does not anticipate any problems.
"As good as I felt today, I don't think I can feel too bad tomorrow, so I think we're ready to go Friday," Price said. "We're going to be checking it the next three days here. I'm supposed to be going on Friday, and that's the way I feel right now."
Price would not deny that he has been worried about his shoulder.
"Yeah, it's been on my mind quite a bit the last week and a half," the southpaw said. "It's something I've never been through. It's something I hope I really never have to go through again. It's something I didn't know how it was going to respond. I didn't know how it was going to feel throwing a bullpen. I didn't know if I was going to bounce back.
"I've never been through this process before, so it was something I was definitely a little bit scared about. ... But I felt good today. I felt very good, so it was a good step forward, so we should be good to go."
Price still doesn't know how he irritated his shoulder.
"I guess this was one of those things," he said. "I don't really know what it was. I don't think it was fatigue. I didn't feel fatigued in Texas. I didn't feel fatigued in Toronto, either. I don't know what it was. It was one of those things, and I feel like it's gone now."
