Nationals right fielder Jayson Werth missed today's spring training workout because back spasms, Manager Davey Johnson said. Johnson expects Werth will be fine.

Johnson had planned to leave Werth in Viera when the Nationals travel to Kissimmee for their spring training game Saturday. Johnson does not expect Werth to miss a significant number of spring games, "but it's not something I'm taking any chances with," Johnson said. "I know he worked out and hit a lot in D.C. So I'm not worried about him."
