Nationals rout reeling Mets

Brady House hit his first career grand slam as the Washington Nationals routed the New York Mets 14-2 on a rainy night at Citi Field.

The blowout featured a seven-run fourth inning that put the game out of reach early.

Mets starter David Peterson had a disastrous outing in his return to the rotation, contributing to the team's ongoing struggles.

The Nationals' dominant performance underscored the widening gap between the division rivals this season.
