WASHINGTON -- A day after having minor elbow surgery to remove a bone chip from his right elbow, closer Drew Storen attended the Nationals' home opener against the Reds wearing a sling.

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."

Nats prospect Rendon placed on disabled list

WASHINGTON -- Class A Potomac third baseman Anthony Rendon suffered a partial fracture in his left ankle while running the bases in a 7-2 loss to Lynchburg this past Saturday, and he has been placed on the 7-day disabled list.

Rendon hurt the ankle in the fourth inning after a hitting a double and later trying to score on a bloop single to center by Justin Bloxom. The Nationals' No. 2 prospect went down with the ankle injury after rounding third base.

"He is in a boot. He is immobilized. He is going to see a foot and ankle specialist on Friday," Nationals general manager Mike Rizzo said about Rendon. "[The doctors] tell me that his season in not in jeopardy. The slight fracture probably heals quicker and cleaner than a bad sprain."

As for Class A Hagerstown outfielder Brian Goodwin, he suffered a hamstring injury in an 8-7 victory over Lexington on Monday. He, too, has been placed on the 7-day disabled list.

Goodwin was 6-for-16 (.375) with two home runs and eight RBIs this season.

"He should be fine in the next couple of weeks," Rizzo said.
