Washington Nationals reliever Will Harris has a blood clot in his right arm and the team doesn’t expect him to be in the bullpen on opening day. Manager Dave Martinez says Harris is leaving spring training camp to be examined by a specialist. The Nationals open on April 1 at home against the New York Mets. Harris last pitched in an exhibition game on March 9, throwing one scoreless inning against the Houston Astros. The right-hander appeared in a “B game” on Saturday.
