House will start at third base and bat fifth in Sunday's game against the Mets.
The 23-year-old will remain in the lineup for a sixth straight game after going 8-for-20 with a home run, a stolen base, four RBI and four runs over the prior five contests. House has made three starts versus righties and three versus lefties during that span, and the Nationals could continue to deploy him in a near-everyday role between third base and designated hitter while he's wielding a hot bat.
