Stephen Strasburg won't start Friday for the Washington Nationals.
Strasburg, who is 8-6 with a 4.35 earned-run average, was limited to four innings in his last outing because of upper-back tightness.
The right-hander is scheduled to throw an extended bullpen session Thursday and Manager Matt Williams said Strasburg would
need at least two days after that before pitching.
