MIAMI — Drew Storen’s rehabilitation from surgery to remove a bone chip from his right elbow will continue at least a few days longer.

Storen allowed three hits and struck out five over two innings Thursday for the Potomac Nationals, the fourth appearance of his minor league rehabilitation assignment.


“His arm strength is not quite where he needs to be,” Nationals manager Davey Johnson said.

So, Storen will make another minor league appearance, this time as early as Sunday for Double-A Harrisburg.

Johnson reported that Storen, who threw 32 pitches Thursday, felt tired in his second inning.

“We just want to make sure he’s ready,” Johnson said. “His arm’s not quite there.”

In four games with Potomac, Storen allowed four hits and struck out six batters.
