Storen said he was relieved to learn that his injury wasn't much worse. He said his arm felt fine, but he started to feel discomfort after having a simulated game in Florida on Sunday.
Storen knew he had a bone chip in his elbow during Spring Training, but didn't think he needed to do anything until after the season was over.
"I figured I was going to get it done after the year was over, but I really couldn't throw comfortably," said Storen. "I wasn't myself when I was throwing the other day. I could tell. I wanted to make sure when I came back, I'm me, not just trying to throw through it."
Storen hopes to be back before the All-Star break, but Nationals reliever Brad Lidge, who knows what Storen is going through having had bone chips removed from his right elbow in 2000 and '09, preaches caution.
"There is really no two ways about it, it [stinks]. It's a slow process," Lidge said. "You want everything to be a gradual incline to where you get back, but it's not the nature of the beast. I think the main thing I'll remind him is that [if] he has a day where things don't go as planned, it's not the end of the world. Your rehab is set for days here and there. ... Hopefully, it goes as smooth as possible."
