"We don't have to any issues with the arm trying to overcompensate," Williams said.
This is the second time this spring Strasburg, who appeared to be OK while walking around the clubhouse Saturday morning, has been scratched from a start, although neither issue has been serious. He missed a start earlier in the spring because of an ingrown toenail, but he still made his pitches that day at the team's Minor League facility.
"It is what it is," Williams said. "Sometimes those things happen, but I don't anticipate anything serious."
Right-hander A.J. Cole, who was optioned to Triple-A Syracuse on Wednesday, will start for Washington in Strasburg's place.
