Nationals ace Stephen Strasburg will not make his scheduled start on Tuesday and will return to the IL, Washington manager Dave Martinez announced on Monday, according to Jesse Dougherty of the Washington Post.
Martinez said that Strasburg felt discomfort during a bullpen session on Saturday, but did not specify exactly what was wrong. The 33-year-old starter is set to undergo an MRI on Monday afternoon and the Nationals expect to have more clarity in the evening, according to Dougherty.
After not taking the mound in over a year, Strasburg made his season debut last Thursday in a 7–4 loss to the Marlins.
