The Cubs finished off a four-game sweep of the punchless Nats Sunday thanks to some power from a Chicago slugger.
Soriano's 16th home run, his second in two games after a drought of 120 at-bats, began the biggest inning of the season for the Cubs. Starting pitcher Kevin Hart also contributed by faking a bunt and punching an RBI single.
The only bright spot for Washington was Adam Dunn. The slugger hit his 24th homer – record for a Washington left-handed hitter.
Despite Dunn’s bomb, Washington dropped to 0-4 under new manager Jim Riggleman, who took over when Manny Acta was fired at the All-Star break.
The Cubs had 16 hits, equaling their season high while the Nats countered with only seven base knocks.
Hart (1-1), who spent the All-Star break pitching at Class-A Peoria, was recalled to make the start. He pitched five innings, allowing two runs and five hits while walking five and striking out one. The hit and RBI were the first of Hart's career.
Chicago's seven-run fourth also included two Nationals errors and RBI singles by Kosuke Fukudome, Derrek Lee and Jake Fox and a sacrifice fly by Ryan Theriot.
Garrett Mock (0-3), who was summoned from Triple-A Syracuse after winning five straight there, allowed seven runs -- four earned -- in 3 1-3 innings for Washington.
The Nationals scored in the second and third on sacrifice flies by Alberto Gonzalez and Ryan Zimmerman. Dunn connected in the seventh.
Next up for the Nats -- a three-game series against the disappointing New York Mets.
