Stephen Strasburg (oblique) fans 11 in Triple-A but no plans to return to Nats

WASHINGTON -- Washington Nationals pitcher Stephen Strasburg says he's doing well after striking out 11 in his latest minor league rehabilitation assignment, but still isn't sure when he'll return to the majors.

Strasburg was in control Monday night, pitching 5 2/3 innings without a walk for Triple-A Syracuse on Monday. There is no timetable for him to rejoin the Nationals.

Strasburgh, 27, was placed on the disabled list July 5 because of a strained left oblique. He missed four weeks earlier in the season because of tightness in his neck.

"I feel good," he said. "Stuff's there, so it's just trying to keep doing the same things and keep working at all the stuff I've been doing. I'm going in the right direction."

Nationals manager Matt Williams said the team is going to get Strasburg to a bullpen session, possibly Wednesday, and they'll evaluate him then. Williams said Strasburg felt fine physically after Monday's effort.

Strasburg is 5-5 with a 5.16 ERA in 13 starts this season for Washington.
