Wang, who is on the 15-day disabled list with a right hip strain, will head home to Taiwan during the break. Manager Davey Johnson said Wang has been throwing to "keep his arm going," though the 32-year-old right-hander is mostly relaxing and getting treatment.
"In fact, I've copied some of the exercises," Johnson said. "There's some pretty good ones, I've never heard of them before, where you can stretch your hips and loosen them up. It's better than having somebody stretch or massage you."
Wang was placed on the DL on July 4 (retroactive to July 1) after struggling to return from a strained left hamstring that caused him to begin the season on the disabled list. Initially slated to be a long reliever after being activated on May 22, Wang briefly replaced Ross Detwiler as the Nats' No. 5 starter.
But in four starts, Wang posted a 1-3 record with a 6.62 ERA. After allowing six earned runs over two relief appearances last week, Wang was deactivated once Henry Rodriguez was healthy enough to rejoin the bullpen.
