Nationals' Strasburg won't throw until left trapezius strain is healed

After undergoing further evaluation, the Nationals' original diagnosis of a left trapezius strain for starting pitcher Stephen Strasburg has been confirmed, manager Matt Williams told reporters Tuesday.

Williams said Strasburg won't throw until the injury is healed, but he might only be down for a matter of days, per CSNwashington.com.

“We have to make sure we determine what it is and fix it,” Williams said. “Whatever’s causing that in his back, we have to see if we can fix it, then get him back out there and allow him to be free and easy and pitch and do what he does best.”

Strasburg went on the 15-day disabed list Saturday after pitching just one inning Friday at Cincinnati. The right-hander is having a tough start to the season, as he is 3-5 with a 6.55 ERA in 10 starts. He has been plagued by poor fastball command through the first two months.

“We’ve looked at it extensively,” Williams said. “[Pitching coach Steve McCatty] has looked at it, all the video. There’s minor adjustments that guys make during the course of a season, but nothing that glares at us that he’s changed or that’s drastically different, no.”
