Given Wang’s command issues, the lack of walks is a good sign. The hip issues, the Nationals believe, compromised Wang’s delivery and caused him to lose the heavy sink on his fastball.

“He threw the ball pretty good,” Johnson said. “He didn’t have a very good defense behind him. They missed a few balls. But other than that, we were encouraged.”

In other rehab news, Xavier Nady went 2 for 4 with a double last night at Class A Potomac. Nady has played six games for Potomac, going 3 for 18 with two walks and five strikeouts total.
