WASHINGTON -- Nationals closer Drew Storen, who is on the disabled list because of surgery to remove a bone chip in his right elbow, is throwing every day from 120 feet on flat ground. It's not known when he will start having bullpen sessions.

Storen is still hoping to be playing in a Major League game after the All-Star break.

"It comes down to throwing right now. Physically, I'm strong enough. It's just getting my elbow strong enough to throw," Storen said.

In Storen's absence, his best friend, Tyler Clippard, has been closing games for the Nationals. Clippard had saved four games entering Tuesday's action against the Mets. How does Storen feel about his buddy closing games?

"It's awesome. It's a lot of fun to watch. He is doing a great job," Storen said. "The bullpen as a whole is doing a great job. That's going to be a key part at the end of the season. I'm very happy to see it."

DeRosa to rest sore oblique until pain free

WASHINGTON -- The Nationals are currently carrying three catchers, but that is expected to change once Mark DeRosa is activated from the disabled list.

When that will be is still unknown because DeRosa's left oblique is still sore. The doctors want him to rest until the soreness goes away.

DeRosa is currently in New Jersey with his father, Jack, who is battling cancer. According to Johnson, Jack suffered a relapse recently.

"Mark is by his father's side right now. So we text back and forth. I told him [Jack] needs you more than we do. It's a good time to give [that oblique] a rest," Johnson said.
