Strasburg experienced discomfort in his neck again following Wednesday's bullpen session and will back off his throwing program, Maria Torres of The Athletic reports.
Strasburg suffered a minor setback in mid-July and backed off mound work briefly, though he was still able to play catch and got back on the mound not long later. A second setback in such a short span of time will likely lead the Nationals to be more cautious this time around, though the team is still determining what to do next. It's possible this pause winds up being another brief one, but nothing in Strasburg's extensive injury history suggests that optimism is warranted.
