Nationals placed RHP Ryan Mattheus on the 15-day disabled list, retroactive to May 21, with plantar fasciitis in his left foot.
Mattheus has felt something in the foot for a couple of weeks now and required an X-ray on Monday. While it’s not believed to be serious, we should know more about his status after he visits a specialist in Baltimore on Tuesday. The 28-year-old right-hander has a 2.25 ERA and 13/7 K/BB ratio in 20 innings of work this season. Chien-Ming Wang has been activated from the disabled list to replace him on the active roster.
