PHILADELPHIA — The X-rays taken on Ryan Mattheus left foot Monday afternoon in Philadelphia came back negative. The Washington Nationals’ right-hander will go to Baltimore on Tuesday to be examined by a foot specialist to figure out the best course of action for the pain he felt Monday while doing some running at Citizens Bank Park.

Mattheus has been dealing with plantar fasciitis for a few weeks, he said, but the doctors have assured him that even if his plantar fascia tore, it would be a worst-case scenario of being out for two weeks.


“We’ll know a lot more tomorrow after I see the specialist in Baltimore,” Mattheus said. “If it’s something that I’m not injuring further, I’ll come right back here and try to get in there tomorrow.”

Mattheus received significant treatment on the foot on Sunday and was unsure if that helped cause what he was feeling Monday but admitted it was the worst it’s felt since it began bothering him a few weeks ago. The soreness occurs, he said, when he plants on his left foot and the arch stretches. 

If Mattheus requires a disabled list stint, the Nationals are expected to have Chien-Ming Wang in Philadelphia on Tuesday anyway to throw a bullpen. The right-hander could be activated to take Mattheus’ spot on the roster.
