CHICAGO (AP) - Adam LaRoche and Wilson Ramos homered, Blake Treinen earned his first major league win and the Washington Nationals beat the Chicago Cubs 7-2 on a rainy Saturday night to sweep a day-night doubleheader.
Gio Gonzalez pitched two-hit ball over seven innings in the opener for a 3-0 Nationals victory.
In the night game, Washington tagged Jeff Samardzija (2-7) for six runs over five innings to salvage a four-game series split.
LaRoche led off the second with a long drive to right for his 11th homer, and Ramos connected to start the fifth, sparking a four-run rally that made it 6-2.
Making his fifth major league start, Treinen (1-3) allowed two runs and four hits in five innings. The right-hander was recalled from Triple-A Syracuse as the 26th man on the roster for the doubleheader.
