WASHINGTON, April 24 (UPI) -- Felipe Lopez hit a grand slam homer in the sixth and tied his career best with six RBI Thursday, carrying the Washington Nationals past the New York Mets 10-5.
Washington downed the Mets for the first time in five tries this year, producing 10 runs in a three-inning span. The Nationals won for only the fourth time in 20 games.
The victory went to Michael O'Connor (1-0), who threw one inning in relief of Shawn Hill.
