TORONTO -- Drew Storen threw off a mound Monday for the second time since undergoing surgery to remove bone chips from his right elbow, and there were no reported setbacks.
Nationals manager Davey Johnson is pleased with the progress his closer is making and seems optimistic -- while not naming a date for his return -- that Storen will be ready to come off the disabled list after the All-Star break.
"He's fine, no problems afterward," Johnson said. "I think he was a little disappointed because he thought he threw a little bit better than he felt. ... But I wouldn't expect anything less. Every time he throws the ball, he wants to throw it through the wall. But he had no problems throwing, so he is right on track."
Storen, who has missed the entire season, had his first mound session on Friday.
The 24-year-old saved 43 games for the Nationals in his second big league season in 2011.
