Washington Nationals pitcher Stephen Strasburg left Friday night's start after just 16 pitches with tightness in his neck, the Associated Press reported.
Strasburg is scheduled to be reevaluated Saturday morning, although neither he nor Nationals' manager Matt Williams mentioned specific tests, The Washington Post reported.
Strasburg was attended to by the team trainer at the mound in the second inning of the Nationals game against the Cincinnati Reds before he exited the game.
According to the Elias Sports Bureau, Strasburg is the first pitcher this season who has recorded fewer than 17 outs in each of six consecutive starts.
The 26-year-old has not pitched more than five innings in a start in May and has only reached the fourth inning in one of his last four starts.
Cincinnati defeated Washington Friday 5–2.
