Strasburg, who had bone chips removed from his surgically repaired right elbow in October, is set to throw two innings against the Atlanta Braves in Lake Buena Vista, Fla.
"We're not going to push him to three at this point regardless of his pitch count," manager Matt Williams said.
"Right now it's just a matter of arm strength and getting everybody going. Once we get to four or five innings and arms start to get tired, then we'll get a better evaluation," Williams added, according to MLB.com.
Strasburg said last week that he had no health issues.
"I feel good," he said. "Ready to rock."
The 25-year-old is 29-19 over four seasons, including 8-9 last season with a 3.00 ERA in 30 starts.
Nationals outfielder Bryce Harper, sent home Sunday with flulike symptoms, is expected to play Tuesday against Atlanta.
Right fielder Jayson Werth, who strained his right biceps while working out Saturday, will be evaluated Tuesday.
