Bryce Harper homered, Ian Desmond had three extra-base hits, Danny Espinosa provided his first two RBIs of the season, and the Washington Nationals beat the Chicago White Sox 5-2 Wednesday night to stay unbeaten at home.
In a game that began 16 minutes late because, the Nationals explained, the umpires got stuck in traffic, Washington starter Jordan Zimmermann (2-0) limited Chicago to two runs and seven hits in seven innings. Both runs scored on groundouts.
Drew Storen pitched the eighth, and closer Rafael Soriano worked around a hit in the ninth for his fourth save in five chances.
Harper hit his fourth homer into the second deck leading off the fourth against Gavin Floyd (0-2), who allowed five runs and nine hits in 5 1-3 innings.
Desmond tripled, doubled twice and scored twice as reigning NL East Washington improved to 5-0 at Nationals Park.
Every Nationals starting position player reached base at least once; the only one without a hit, Kurt Suzuki, walked three times.
