Stephen Strasburg insists he won't miss his next start, but the Washington Nationals right-hander is dealing with tightness in his forearm.

He was examined by a doctor after his start against the Atlanta Braves on Monday night.

"I think he's got a little tightness in his forearm," Washington manager Davey Johnson said. "So they're going to put him on some medication."

Johnson said the hard-thrower will have to show he is ready to make his next scheduled start.

Strasburg insisted he won't miss a start.

"I'm not missing my next start," he said. "I'll tell you that right now."

Strasburg had lost a career-worst four straight starts before pitching six innings and getting a no-decision. He is 1-4 with a 3.13 ERA.
