Nationals starter Stephen Strasburg threw a bullpen session on Tuesday night and is scheduled to throw a simulated game on Thursday.

Strasburg has been on the 15-day disabled list since last Thursday with stiffness in his right shoulder.

"If all those things fall into place, he'll be on schedule to pitch on Tuesday," Washington manager Jim Riggleman said.
