"Feels like nothing ever happened," Reed said. "If anything, my arm feels stronger because of all the work I've been doing in the training room."
Now it's just a matter of working his way back up to throwing bullpens before he can get into games.
"I'd say by the 20th [of March] I'm for sure off the mound," he said.
If that's the case, Reed said he would have no problem being ready for the April 6 opener, but manager Chip Hale said the club would err on the side of caution.
"We want him ready and the worst thing we can do is say, 'Hey you're going to throw two or three times and now we're going to open the season,'" Hale said. "If that's the case, he may have to start on the DL, but we're a long way away from that."
