Nationals starting pitcher Stephen Strasburg exited his start on Tuesday against the Marlins after three innings, giving up two runs on 64 pitches, with no official reason from the team, reports MLB.com. 

Strasburg appeared to have some sort of issue early on as Nationals manager Matt Williams, pitching coach Steve McCatty and the trainer visited the mound in the second inning for an unknown reason. 

Strasburg remained in the game until his turn at bat in the third inning, as pitcher Doug Fister pinched hit for Strasburg and delivered a single.

The Nationals fell to the Marlins, 2-1, Tuesday and Strasburg suffered the loss to fall to 2-3 on the season.
