Nationals reliever Ryan Mattheus will visit a specialist in Baltimore on Tuesday to determine the severity of plantar fasciitis in his left foot. Depending on the diagnosis, Mattheus could either return in time to pitch Tuesday night or he could land on the disabled list and miss two weeks.
Mattheus has been pitching with soreness in his foot for about two weeks, he said, and he aggravated the injury Monday afternoon while jogging in the outfield. Mattheus underwent an X-ray Monday evening, which was negative.
Mattheus allowed two hits and a walk but no runs in one inning yesterday. For the season, Mattheus has a 2.25 ERA and 13 strikeouts with seven walks in 20 innings. With Henry Rodriguez no longer the Nationals’ clear-cut closer, Mattheus could be one of the candidates to get the ball in the ninth inning.
